How to make a moped out of a bicycle at home. How to make a homemade moped from a bicycle? DIY motorbike from a chainsaw

In conditions modern life everyone can provide themselves with personal motorized transport if they know how to make a moped from a bicycle.

Before considering ways to transform a pedal horse into a moped, you need to clarify what this moped is. This is a vehicle whose engine capacity does not exceed 50 cubic centimeters. In theory, this vehicle develops a speed of no more than 50 km/h. Well, the most important difference from a motorcycle is that in the classic version the moped has a bicycle drive with a chain drive rear wheel. The movement begins like a bicycle, and then the engine starts. In general terms, this is a moped. Now about how to build it.

First of all, you will need a motor. Nowadays it is very easy to get it. The market is full of gasoline engines for brush cutters, chainsaws and even motor cultivators. The most compact and lightest are, of course, engines from scythes and saws. However, not all of them have sufficient power. If you want to ride without pedaling and with the breeze, then you need an engine with a power of two or more Horse power. If the engine still has less power, then you can use it. One of the advantages of compact motors for scythes and saws is that the gas tank is mounted directly on them, which in turn will save space and eliminate the need for additional hoses.

In the very simple version The engine is mounted above the rear wheel using clamps. To do this, you need to make a base for the engine. It is made of steel (thickness no less than 3-4mm) by welding. The design depends on the design of the bike. After securing the motor, it needs to be connected to the wheel.

Rotation from the engine to the wheel can be transmitted either through drive belt, or through a chain. In the first case, you will have to mount a pulley on the wheel - install the rim bicycle wheel smaller diameter. In the second case, you will need to install a gear.

Now all that’s left to do is move the gas to the bicycle handlebars. It's quite simple. The only thing you need is a cable of sufficient length and a handle (can be the same as that of a manual bicycle brake). All this can be easily purchased at any auto store, bicycle supply store, or found at a scrap metal collection point.

Of course, depending on the design features of the bicycle, some additional nuances may arise. You'll have to put your hands and head to work. But when everything is ready you will need the article ““. Shurikens may come in handy to fend off friends who are chasing you, shouting “let’s go for a ride.”

And in this video you can see a finished version of such a hand-made moped in action:

Today, almost anyone can make a moped from a bicycle for personal use. This technique can be found especially often in rural areas. Basically, such a moped is assembled on the basis of an old bicycle, to which a small-volume gasoline engine is adapted.

Before you start upgrading, you need to find out what a moped is. It is a vehicle with an engine capacity of no more than 50 cm3. Maximum speed The speed that a moped can reach is 50 km/h. Its main difference from a motorcycle is the chain drive from a bicycle. In this case, to start moving, you need to pedal until the engine starts.

Selection of parts and materials

In most cases it is used, since this is the most suitable option for a bicycle. In addition, it can be easily purchased at a low price. Can buy modern bicycle and a better engine, but from a financial point of view this is not entirely profitable. For this amount you can easily buy a good Japanese moped with mileage, which will eliminate the need to make it yourself.

Also, recently, some motorcycle manufacturers have begun to produce special kits for creating homemade mopeds from bicycles. To install such a motor, you must follow the instructions that came with the motor. If all points are followed, installation will not cause any problems. But many still choose to create a moped with a chainsaw engine, since it turns out to be a little cheaper.

The first step is to determine the power of the motor. Engines with one horsepower are not capable of propelling a bicycle on their own; to do this, you will have to accelerate it by pushing off the ground with your feet. A two-horsepower engine copes with this task better. Such an engine is capable of accelerating on its own and climbing uphill without the help of pedals.

In addition to the engine, you need to get a pulley, which can serve as a rim from children's bike, a belt that will transmit torque to the wheel. In addition, you will need tools and materials to construct the motor mount. The easiest way to mount the engine is above the rear wheel. To do this, you need to take care of strengthening the trunk, as it will not support the weight of the motor.

For the manufacture of engine mounts, it is best to use steel parts with a thickness of 4 mm. But it is worth remembering that creating a powerful frame increases the weight of the moped and the load on the wheel, which will lead to a decrease in motor performance. It is necessary to develop a structure that is strong and at the same time not too heavy. It can be connected to each other using a welding machine or bolts.

Assembling the structure using the second method is much easier, but of lower quality, since the bolts can unscrew when driving, which in turn can lead to sudden destruction of the entire structure. The engine can also be attached to the bicycle frame with ordinary steel clamps. This is a simple and reliable connection.

After this, it is necessary to mount the pulley on the drive wheel. As already specified, the role of a pulley can be played by a wheel from small bike. The main thing is that its diameter is half the size of a moped wheel. You can also use an additional sprocket instead of a pulley, but for this you will need to change the belt and the chain. Both the first and second solutions have the right to life, it all depends on the available spare parts and materials.

After installing the engine and belt drive, it is worth proceeding with the equipment of the bicycle handlebar, on which the accelerator handle should be attached. To do this, you can use a metal cable. You can buy it at a construction or hardware store. It must be pulled along the frame, in the same way as the brake drive. The accelerator handle can be made from the brake handle. This method is the simplest engine control, that is, the increase in speed will depend on the force of pressing the handle.
This type of moped has become a favorite vehicle for many.

Since they consume very little fuel, do not require expensive repairs and maintenance, and you do not need a license to drive them. In addition, the cost of these homemade mechanisms is quite low. In some cases, it is used because it is a little cheaper, but safer. All mechanisms are mounted in a certain place on the frame, for which special fastenings are provided.

Making a moped from an old bicycle is not such a difficult task that anyone can do. After assembly, it is necessary to run it in near the assembly site so that unexpected problems do not arise during a long trip.

The versatility of gasoline chainsaws is proven not only by their multitasking and functionality, but also by the abundance of useful homemade products that craftsmen have learned to make with their own hands. They save money on the purchase of expensive factory devices, for which most people simply do not have the money. But, as they say, the need for invention is acute. Therefore, when talking about chainsaws, many people imagine not only logging or pruning an orchard, but also winches, ice drills, boat motors, grinders, sawmills, which technically competent craftsmen have learned to adapt from everyone’s favorite gasoline-powered tool.

Moving equipment deserves no less attention - bicycles, mopeds, go-karts, ATVs and much more that can be assembled using a chain saw with gasoline engine. We will talk about how and from what to recreate them and surprise others with an incredible motorized design in this article.

DIY motorbike from a chainsaw

Not every happy owner of a bicycle is delighted with the need to pedal and waste his energy. A motorized bicycle is more convenient and less expensive in terms of power.

Making a bicycle with a chainsaw motor with your own hands is not as difficult as it seems at first glance. For this you will need:

bike;
a saw with a gas engine power of at least 2000 W - this indicator will determine whether it can start moving. As practice shows, the engine power is 2 hp. It is enough for a motorbike to reach a speed of up to 40 km/h;
reservoir for the future fuel tank;
cable from an old bicycle;
a handle to allow you to adjust the throttle;
bolt ties, nuts and other small consumables for creating fasteners;
connecting elements for creating a connection between the wheels and the engine.

The process of installing a chainsaw engine on a bicycle is as follows:

we assemble the drive shaft - remove the rear wheel tire and install a tire with a diameter of up to 2.5 cm. This equipment will help to adjust the engine speed and, like a gearbox, reduce the number of revolutions;
We use electric welding to weld a stand from the corners - it will help install the engine from the chainsaw;
alteration of the clutch - you can use a centrifugal one from a factory saw, connecting it to the wheel;
we adapt the gas tank - it can be located next to the engine, or on the frame;
we attach the wire from the engine ignition system to one of the bicycle handles;
attach a cable from the carburetor to the gas handle so that throttle control is simple and quick;
We equip the motorbike with protective equipment: mirrors, a flashlight, and proceed to testing homemade bicycle from a chainsaw.

As you can see, installing a chainsaw motor on a bicycle is not so difficult.

How to make a moped from a chainsaw?

The youth dream of most of our fellow citizens was and remains a moped. It develops a higher speed and has a structure that is more advanced than the motorbike described above. Buying a ready-made moped is not a cheap pleasure. We will tell you how to make it from scrap materials.

For this you will need:

a motor from a working, powerful saw (in our version, this is the “Friendship” model);
2 wheels from an old bicycle;
pipe with a diameter of 2 cm (metal);
cable;
bicycle sprockets; as well as forks;
old spare parts from a motorcycle - a ready-made fuel tank, a headlight, and, if desired, a seat, although this can also be made with your own hands;
steering part;
gas lever.

The process of creating a moped looks like this:

we cook the frame to which we connect the wheels from the bicycle, forks, as well as a gas tank and a lantern;
we adapt the motor - the composition of the installation will depend on the configuration of the frame;

screw on the gas tank and battery;
we check that the newly installed elements do not dangle;
We make a chain drive - it will allow the wheels to receive the torque of the motor and move. You can use a belt instead of a chain pulley. But we must not forget that its wear will be noticeably higher;
we set up the ignition system - we connect the battery and brake lever to it;
adjust the exhaust pipe.

The assembly process is complete: you can start testing the moped.

Do-it-yourself chainsaw go-kart: step-by-step assembly

Karting is a modern vehicle that can cover a significant distance in a short period of time. An exclusive kart is the dream of every car enthusiast. You don’t have to race with it: you can easily drive it on rough terrain, on rural roads, and in general anywhere where a larger car cannot pass.

Among possible options equipment, homemade go-karts made from chainsaws have gained enormous popularity - no less powerful and productive than their serial counterparts. Let's look at it step by step.

Preparatory stage

It begins with detailed drawings and design. We suggest that you familiarize yourself with the finished drawing, which will save time on design;

The proposed overall dimensions are suitable for a person of average height. For teenagers and tall people the design must be adjusted to their individual parameters. For teenagers, you can use a different scheme presented below.

Collecting the design base

This is a chassis, the manufacture of which will require:

square pipes (up to 10 m);
steel pipes;
thick steel plate;
equipment for blocking the bottom;
armchairs.

The process looks like this:

The pipes are cut according to the proposed scheme and welded using electric welding.

This is what should happen after welding;

the front axle is equipped with plugs;
the rear axle is aggregated - it is welded to the frame itself in such a way that its rotation is ensured;
the bottom is cut out of metal or durable wood according to the drawing and fitted to the frame;
seat - in this case, you don’t have to mess around and take a ready-made one from an old kart or car.

Karting equipment with motor

remove the motor from the chainsaw;

We make a base for the motor - from a steel plate and a corner. Its pulley must coincide with the last frame structure;
screw the pulley;
we take 2 metal rods, which we bend at a right angle - this will be the kart steering wheel drive;

adjusting the brakes - it is desirable that the braking applies to all 4 wheels. Don’t forget about the brake pedal: pressing the brake with your hands will be very inconvenient;

we equip the go-kart with wheels – small-diameter wheels from an old racing car will do;
we set up the ignition - connect it to the throttle valve and the gas handle;
reliability control, assembly and testing of the finished unit.

Go-karting is a luxury for the average person, but with the help of available tools you can create a budget version of it - a go-kart with a chainsaw engine.

An equally famous homemade product that the domestic “Kulibins” learned to make. To recreate it we will need:

a scooter designed to support the weight of the person who will operate it. It is desirable that it initially have a manual braking system. The pneumatic wheelbase of the scooter must be durable;
a chainsaw from which the engine is removed - medium and high-power models are suitable.

The process of assembling a scooter looks simplified compared to previous homemade products:

First, remove the motor base and secure it to the back of the scooter frame. Make sure that the motor and wheel sprockets match;
we attach a manual accelerator with ignition of the chain saw - this way the operator can control the moving process;
If necessary, the scooter is equipped with a brake pedal, but in most cases, the lever for manual control of the scooter is enough for its full operation.
testing a scooter made from a chainsaw - if it is working properly, the new motorized device is ready and can be used.

Homemade children's ATV from a chainsaw

The last homemade product that we will look at will be dedicated to ATVs. In fact, to assemble an ATV you need similar materials as for a go-kart or tricycle:

engine from an old powerful and working chainsaw;
gearbox – increases engine thrust and takes over its operating speed;
ATV frame – it should be stronger and more stable;
the driver's seat is good if you have an old moped seat: a teenager will be more comfortable in it than in a bulky car seat;
wheels with rough tread, diameter of at least 34-35 cm each. This will improve the cross-country ability of the ATV and make it similar to an SUV.

If desired, the prefabricated structure of the ATV can be improved to perfection with shock absorbers: the maneuverability of the ATV will increase, and the operating stroke will become smoother.

Homemade vehicles are cheap, but not always reliable. They can only be used in strict compliance with all safety regulations.

Naturally, over time, any cyclist wants to give their leg muscles a rest, and they think about equipping their favorite vehicle with a motor. Simply pedaling is a thing of the past. If a cyclist is already old, going long distances without a motor is already inconvenient and uncomfortable.

When you ask the craftsmen why they need such a vehicle, since you can just buy a scooter or moped, they answer that you can understand and feel all the joy of a homemade design only in the process.

In addition, a moped or scooter would be inconvenient, for example, for a woman. And here everything is simple. A woman can easily saddle such a horse and go about her business.

Bicycle and chainsaw - where is the connection?

As mentioned above, the motor from a regular chainsaw is ideal for equipping a bicycle with it. How to assemble and install this unit on a bicycle whose manufacturer did not think about it in advance? Let's try to dot all the i's.

Optimal motor power

The chainsaw engine has a power of 1.5 horsepower. And it’s not surprising that some cyclists think that such a weak motor won’t even be able to move a larger bike. For example, there are bicycles that weigh, together with a middle-aged man riding on them, almost 100 kg. It turns out there's no need to worry. And the motor from a chainsaw can handle such a load. The bike will accelerate easily and quietly pick up a speed of 30-40 km/h, which is quite normal for a bike.

Overclocking

True, acceleration cannot be called fast. Everything will happen quite slowly, but this will not interfere with a comfortable ride. In addition, the cyclist and his loved ones will not feel the nauseating smell of gasoline, and such a bicycle, as usual, can be safely stored in his apartment.

Noise

Some cyclists do not want to listen to the loud noise that a chainsaw motor makes, but there is nothing they can do about it. You will have to put up with the characteristic cracking noise that a chainsaw makes and the noise while moving.

Motor mount

It will no longer be a bicycle with a chainsaw engine, but a real moped. The power unit will be mounted directly above the frame and mounted under the saddle. It will be possible to fix it well and firmly if you make a homemade clamp from any metal plate.

There is another option - buy them ready-made. Such clamps are equipped with perforations that regulate the height of the motor, but this is no longer so important.

Sleeve

Special washers and screws will be responsible for securing the bushing. The bushing itself is designed to tension the belt from the engine. There are different types of bushings, or rather they have different diameters. It all depends on the size of your bike's wheels. If the wheels are huge, then purchase a hub for 28-inch ones. Interestingly, the inside of these bushings has a rubberized surface. How do you like this moped?

We must remember that the drive belt is selected depending on the diameter of the bushing. In addition, it is important to know that the bushing is always attached smoothly and without distortion. Otherwise, there is no need to think about any normal operation of a bicycle with a chainsaw motor.

Gas lever

The accelerator pedal is a lever in this case, as a moped of this type should be. The lever is controlled by a cable that regulates the damper angle. The lever is completely reminiscent of a bicycle brake component. This has the advantage that you can gas without turning the handle, as required by a moped, but simply by pressing it, as required by chainsaws.

It is recommended to route the lever cable to the bicycle brake control handle. You will have to get rid of the brakes themselves. In this case, they will be completely inappropriate, because given the low weight of such a vehicle, when you press the brakes at speed, the cyclist will definitely do a forward somersault and could damage himself.

On the other hand, sellers of bicycle motors offer a special lever mounted on the handlebar, but here everyone decides depending on individual preferences.

As a result, by installing a chainsaw motor on a bicycle, we will get an excellent moped without spending a lot of money. Such transport will bring a lot of joy and pleasure, will give you the opportunity to maneuver well and pass the most difficult roads easily and simply.

In modern life, everyone can provide themselves with personal motorized transport if they know how to make a moped from a bicycle.

Well, the most important difference from a motorcycle is that in the classic version the moped has a bicycle drive with a chain drive to the rear wheel. The movement begins like a bicycle, and then the engine starts. In general terms, this is a moped. Now about how to build it.

First of all, you will need a motor.
Nowadays it is very easy to get it. The market is full of gasoline engines for brush cutters, chainsaws and even motor cultivators. The most compact and lightest are, of course, engines from scythes and saws. However, not all of them have sufficient power. If you want to ride without pedaling and with the breeze, then you need an engine with a power of at least two horsepower. If the engine still has less power, then you can use it.

Of course, depending on the design features of the bicycle, some additional nuances may arise. You'll have to put your hands and head to work. But when everything is ready, you will need the article “How to make shuriken from paper.” Shurikens may come in handy to fend off friends who are chasing you, shouting “let’s go for a ride.”

And in this video you can see a finished version of such a hand-made moped in action:

vopros-kote.com

You should start by finding a suitable motor. The heart of a chainsaw is suitable for this role. Use Friendship. Remember power. A homemade moped will not be able to move if the engine power is less than 2 liters. With.
To create a bicycle with a chainsaw motor with your own hands, you will need other components:

battery;
pulleys, gears;
transmission belt or chain;
drive cable;
clamps for fastening;
tools: screwdriver, pliers, etc.

The main place where the elements of the future unit will be placed is the bicycle frame. Here, the battery is mounted using fastening clamps on the top pipe, the engine is mounted at the junction of the pipe passing under the saddle and the front bottom pipe, and the gas tank is nearby.

The next step in assembling a bicycle with a chainsaw engine is the manufacture of transmission wheels and pulleys. With the help of these elements, the force created by the motor is transferred to the rear wheel.

Use wheels with an external stop the size of a music disc to create pulleys.

Do not forget about the strength and reliability of fastening parts.

Assembly of the moped continues, we mount the assembled parts:

We connect the front transmission unit to the engine shaft.
We attach the second pulley to the rear wheel hub.
We put a belt on the transmission units. If using a chain, use gears instead of pulleys.

Having installed the chainsaw motor on the bicycle, we proceed to the connection. We connect the working compartment of the engine to the battery and install the ignition mechanism. An integral step in assembling a moped is connecting the handle for the brake and the motor. Adjust the tension of the connecting cable so that the handle starts the engine easily.

Chainsaw ignition for a motorcycle

Chainsaw spare parts are also used to modernize outdated or in need of repair vehicles, such as a motorcycle. To improve this vehicle, a saw ignition system is often used.

You will need:

flywheel;
flywheel spacer with key;
fan;
coil with high voltage wire;
aluminum plate for attaching the coil;
bolts, nuts.

Chainsaw ignition is suitable for Ant and IZH Planet motorcycles. Unlike a magneto, this ignition is reliable and durable, and is not afraid of shaking and water.

For correct assembly moped with your own hands, reliable service, for remodeling and designing other equipment, listen to the advice:

Before assembling the motorbike, make sure that the main part - the bicycle - is in optimal technical condition. Modernization will increase the load on all its parts.
Check the condition of the gasoline tank carefully. Fuel should not spill out, as this may cause a fire.
In addition to engine power, don't forget about volume and weight. The volume should not exceed 50 cm³, weight - no more than 6 kg.
When installing the belt, make sure that the part is held firmly on the wheels, otherwise the accuracy of the impulse transmission from the motor to the wheel will decrease.
Using a chainsaw motor, you can independently design other equipment: a go-kart or a tricycle. You will have to make an effort: weld a strong metal frame, prepare a working gearbox.
With a strong frame, gearbox, driver's seat, wheels with a diameter of at least 35 cm and a saw engine, try to construct an ATV.

Don't throw away spare parts from old equipment. You can breathe a second life into them and create a convenient means of transportation.

Option 1: how to quickly assemble a moped with a gasoline engine

Before you start creating a new moped from a bicycle, you need:

bike;
gasoline engine and gas tank;
battery;
pulleys or gears;
transmission belt or chain;
drive cable;
fastening clamps.

Recommended power – 2 l. s., and the engine volume should not exceed 50 cubic meters. see. A weaker engine will not allow you to move the bike; you will have to pedal for a while. An engine of sufficient power can be taken from an old moped. Other options are with a chainsaw or lawn mower.

The working unit of the engine, gas tank and battery are securely fastened to the frame using fastening clamps. Convenient location:

on the top pipe there is a battery;
the junction of the lower front and seat tubes is the engine;
Next to the engine is a gasoline tank.

At the next stage, you need to make pulleys - special transmission units through which the engine force will be transmitted to the rear wheel. The source material for the pulleys can be small wheels with external barriers, the size of a CD. Mandatory conditions are the strength of the material and reliable fastening.

Do-it-yourself installation of pulleys on a bicycle:

The front gear wheel is attached to the motor shaft.
A second pulley is attached to the hub of the rear wheel of the bicycle.
A belt is placed on the pulleys. The tension force is approximately the same as that of a chain. The belt must hold firmly to the wheels; this determines how accurately the engine will transmit force to the wheel.

If a chain drive is used instead of a belt drive, then gears are installed on the motor and wheel instead of pulleys.

So, the transmission is ready, now let's move on to connecting the engine:

The working motor housing is connected to the battery.
Assemble the “ignition” mechanism: a regular brake lever is attached to the steering wheel, then it is connected to the engine body through a cable.
Set the tension so that the engine starts freely through the handle.

Option 2: assembling a moped with a gas engine

This is an advanced method, and the result is more reminiscent of a real moped. To make it, we need:

gasoline engine;
moped parts: wheels, shock absorbers, exhaust pipe, brakes;
proven bike frame;
tools.

Since here we are going to get a real moped, the frame must have increased strength and weight. Also, mopeds have a slightly different frame design, which may require some modifications.

Wheels from a moped are put on the frame. It will be necessary to change the fork design, since the width of the wheels will be wider than the distance between the dropouts. If possible, install shock absorbers on the fork.

Carefully overhaul the moped power unit and replace all faulty parts. The propulsion system will require separate place, a welded metal platform at the bottom of the frame would be a good option for this. The engine and fuel tank are secured to the site using metal fasteners. It is better to place the battery closer to the steering wheel. An exhaust pipe is connected to the bottom of the engine. The pipe must be firmly secured to the frame so that it does not dangle while driving.

Remove the pedals and chainring from bicycle frame.
Install sprockets on the rear wheel of the moped and the engine shaft. A star on a wheel with a larger diameter.
Place the rear wheel on the frame.
Connect the stars using a chain.

Motor connection. The clutch and throttle valve are connected to the ignition lever via drive cables. The tension is selected so that the engine can immediately start and start spinning the wheel.

Brakes. If only one brake (for example, the front brake) may be sufficient for a bicycle, then it is better to play it safe and install them on both wheels. The rear one can be used as the main one, and the front one as an auxiliary one, to adjust the speed.

In general, a homemade moped based on a bicycle will look like this:

Since a vehicle equipped with an engine moves faster than a regular bicycle (this is why the modification is intended), for safety reasons it is necessary to install lighting devices on it. Personal protective equipment – helmet, knee pads and special shoes.

How to make an electric bike

If you don’t want to bother with a gasoline engine, there is another option - install an electric motor. It can be purchased or installed from another device. The first option for creating electric mopeds is preferable, since the engines already provide the necessary power.

Options for installing an electric drive on a bicycle are a wheel motor and a separate engine on a chain or belt drive.

The wheel motor differs from the usual one by the presence of a drive mechanism in the central part. It is connected to the control unit using wires. A significant advantage is the ability to make the bike front-wheel drive without making changes to the classic transmission. And if you wish, you can even install two motor wheels. Installation is quite simple, provided that the bike itself allows it. However, it’s a stretch to classify a bike with such wheels as a moped.

An electric moped, that is, an analogue of the one discussed above, is a completely different matter. Of course, an exhaust pipe will not be needed here - this is a plus both in terms of reliability and overall weight.

Assembling an engine from scratch at home will be problematic, so let’s look at how to install a ready-made shaft motor.

Progress:

Install a new sprocket and belt pulley onto the carriage axle.
A shaft with a drive pulley is attached to the seat tube.
The pulleys are connected by a belt.
The shaft is connected to a power source through wires.
Route the wires from the battery to the switch on the steering wheel.

The location of the battery is on the lower front tube of the frame or trunk. Electric motor operation diagram:

When the electric motor is turned on, the rotating roller engages the rear tire tire, pushing it.
The pulleys and front sprocket transmit torque to the transmission.
Changing gear causes a change in torque output. At the same time, the rotation speed of the roller remains constant.

DIY electric bicycle:

Additionally, you can connect a second shaft to the front wheel by connecting it to the driven pulley of the main drive.

The engine allows you to reach the optimal speed faster and maintain it longer. A moped on a bicycle base is a budget option become the owner of a faster and more powerful vehicle. Transforming a bicycle into a moped in most cases does not make irreversible changes to the design, so it is possible to return everything to its place.

As a child, every boy dreamed of installing an engine on his bicycle; today it has become much easier to do this. At the moment, there are already ready-made solutions for such modifications; for example, you can buy a ready-made kit and all you have to do is install it on your bike. That’s it, after this the “great” will turn into a small moped, capable of driving up to 50 km/h, or even more.

Such transport is beneficial for those who often go to the country, to fishing, to the village, to the garage, if it is far away. On such a bicycle moped, fuel consumption will be minimal; there is probably no other vehicle that would consume even less fuel. In addition, even if you run out of gas, you can get to your destination in the classic way, using pedals.

Another advantage of this type of equipment is that it does not require a driver’s license, because in fact it is still a bicycle, since you can only turn on the engine outside the city.

Specifically, this article will discuss how you can install a chainsaw engine on a bicycle. Many people have unwanted chainsaw motors or even old chainsaws lying around in their garage. A motor from a lawn mower is also perfect for this purpose.

Materials and tools for homemade work:

1. First of all, you will need an engine. The more powerful it is, the faster the bike will go. On average, today there are chainsaws with a power of 1.5-2 horsepower, this power is quite enough to ride a bicycle moped at a speed of about 30-40 km/h.
2. Capacity for creating a gas tank. It is best, of course, that it be made of metal, it will be safer. But you can also use plastic containers.
4. Bicycle cable and throttle handle to control the throttle.
5. Wires and switch for connecting the engine ignition.
6. Bolts, nuts, elements to create a bracket with which the engine will be attached to the frame.
7. Pulleys, belts, chains and other elements thanks to which the bicycle wheel will be connected to the engine.

The process of equipping a bicycle with a gasoline engine:

Step one. Deciding on the type of motion transmission
Perhaps the most difficult thing in this homemade product is transmitting the movement from the motor to the wheel. Here it is important to correctly calculate the gear ratio. If the gear ratio is small, the motor simply may not be able to handle such a load and the bike will not move. If the gear ratio is too large, the bike will ride very slowly, and the engine, operating at high speeds, will overheat.

You can calculate the gear ratio using the example of one of the authors who managed to assemble a similar technique. With an engine power of 1.78 horsepower and a speed of 12,500 rpm, it used a gear ratio of 1:26. The chainsaw used was a Homelite CSP3314 model.

The easiest way to transfer movement from the pulley to the wheel is directly from the motor, that is, according to the same principle as a dynamo works. If you approach the process more professionally, then the rear wheel is equipped with an additional sprocket or pulley, and then connected to the engine using a belt or chain. Of course, it is best to use a belt drive, since the chain can fly off with such homemade products, and in general it is unsafe.

Step two. Clutch
The clutch is also very important element in this type of transport. There are two options here on how to do it. The chainsaw already has a centrifugal clutch, that is, it is a clutch that automatically engages at certain speeds. So the wheel can simply be connected to this clutch, this is the simplest option.

Some other DIYers do not use the saw clutch, but connect it to a bicycle ratchet. This system works very simply: after accelerating and releasing the gas, the bike rolls by inertia, while the ratchet is not interconnected with the wheel. That is, having “turned the lawn” once, you can then roll in a straight line at idle for a very long time.

Step three. Installing a gas tank and connecting the control system
The gas tank can be installed directly next to the engine, but for safety it is best to place it on the frame. But in this case, you will need a hose that needs to be pulled along the frame to the engine.

As for the ignition, everything is simple here, you need to stretch the ignition wire from the engine, and make a switch on the handle so that the engine can be turned off if necessary.

Also, to control the engine, you need to make a throttle handle, it can be borrowed from mountain bikes(buy ready-made). You need to remove the lock from the handle so that it moves smoothly, and then connect the cable to the carburetor throttle valve.

That's all, after assembling the homemade product, you can start experimenting. Of course, it is important to check the brakes and install an additional front brake if you do not have one. The engine starts classically, with a kickstarter, just like a chainsaw.

The only drawback of this technique is the sound of a chainsaw, which will scare passersby. But if you try, this problem can also be solved by equipping the engine with a small muffler.

It would seem that absolutely incompatible things will not allow one to obtain a truly original invention, but in practice this assumption has been refuted more than once. In particular, for those who do not know how to make a moped with only a bicycle and a chainsaw, this article will be very informative.

Moped with gasoline engine

If you don’t want to refuel your car every day, and riding a bike is too tiring, then a homemade gasoline moped will be the ideal solution to your problem.

What do we need

Nowadays, there are many ready-made kits that include an engine of the required power and other parts necessary to remake a bicycle. Purchasing such a kit is an excellent option for those who want to become the owner of a bicycle with a motor, but do not have the opportunity to make fasteners with their own hands or select a suitable engine.

However, there are situations when, despite possible difficulties, you want to do all the work yourself. In this case, you should start by choosing a suitable power unit, the role of which may be one of the parts of old and unnecessary household utensils. A lawn mower or chainsaw are the most suitable donors for a heart transplant, but do not forget about the power of each such unit. So, a homemade moped from a bicycle should be equipped with a 2 hp engine. and a volume not exceeding 50 cm3. A weaker motor will not be able to move the bike, and you will have to pedal for a while.

In addition to the powertrain, you will also need other parts: battery, pulleys and gears, transmission belt (this can be replaced with a chain), drive cable and mounting clamps. Useful tools include screwdrivers, pliers, wire cutters and other components of an auto mechanic's kit.

We equip the frame

The bicycle frame becomes the main location for all the parts and elements of the future moped. In particular, the engine, gas tank and battery are attached to it using mounting clamps. Most good option their locations are as follows:the battery is on the top tube, the engine is at the junction of the lower front and seat tube, and the gasoline tank is directly next to the engine.

We make pulleys and install them

The next step on the path to creating a moped with your own hands is the manufacture of pulleys - special transmission units through which the motor force will be transmitted to the rear wheel. As necessary materials You can use small wheels (about the size of a CD) complemented by an external barrier. Required condition when creating pulleys, this is the strength of the parts used and the reliability of their fastening.

Installation of the specified parts on the bicycle is carried out in the following sequence:

1. The front transmission wheel is connected to the engine shaft.

2. The second pulley is attached to the hub of the rear wheel of the bicycle.

3. Then a belt is put on the pulleys, setting the tension force like a chain.

Motor connection

After the transmission is installed on the bicycle, you can proceed to connecting the power unit. To do this, its working body is connected to the battery and the “ignition” mechanism is assembled. The motor installed on the bicycle is connected to the brake handle, which is also an integral part of assembling a moped with your own hands. The tension of the connecting cable must be set so that the engine can be started freely through the handle.

Assembling a moped with a gas engine

Compared to the previous option, this method will allow you to get a more “advanced” vehicle that almost completely corresponds to a real moped.

What do we need

To accomplish this task, you will need the gasoline engine itself, spare parts from a real moped (wheels, shock absorbers, brakes and exhaust pipe), a strong, welded bicycle frame and working tools (including a welding machine). Considering that in this version you are going to turn the bicycle into a real motorcycle, its frame must have the appropriate weight and strength. You can try to find a part from a small moped, but if that doesn’t work, then a “skeleton” from a bicycle in the “Stork” or “Yew” style will do.

Preparing the frame

Suppose you were unable to find a ready-made moped frame, which means you will have to strengthen the bicycle one. To do this, you will need a welding machine and an additional pipe, which is welded onto the existing structure, thereby connecting the seat and steering part. However, it must be said that this is not the only possible way to increase strength, and instead of a pipe, iron strips can be used.

By the way, the power plant requires a separate place, and the best option there will be a welded metal pad located at the bottom of the bicycle frame. The engine and gas tank are attached to it using metal fasteners. It is better to place the battery closer to the steering wheel, and connect the exhaust pipe to the bottom of the engine.

Create torque

The next step on the path to creating an electric bike with your own hands is organizing the torque transmission system of the power unit. First you need to remove the pedals and the front sprocket from the bicycle frame. Then sprockets are installed on the rear wheel of the moped and the motor shaft (the star is located on a wheel with a large diameter). After this, the rear wheel is put on the frame and the sprockets are connected using a chain.

Connecting the engine

Having completed all the steps described above, all that remains is to connect the motor correctly. To do this, the clutch and throttle valve must be connected to the ignition lever via drive cables. The tension force is selected so that the motor can immediately start and begin to spin the wheel. As soon as you connect the power unit, consider that you have already succeeded in making a bicycle with a motor.

It is no secret that a vehicle equipped with an engine will move faster than a regular bicycle, so for safety reasons it is also worth installing lighting devices, and the driver himself must use a helmet, knee pads and special shoes. That's all. Another answer to the question “How to make a motorbike with your own hands?” I'm ready now.

Creating an electric bicycle

If you don't like the idea of using a gasoline engine on a bicycle, then you can consider an alternative option for upgrading this vehicle using electric equipment.

Advantages of Electrical Equipment

The emergence of modern electric vehicles has allowed humanity to appreciate all the advantages of this type of transport. An environmentally friendly and economical car almost immediately gained worldwide popularity, easily “telling” car enthusiasts about all the privileges of using electric engines. Therefore, it is not surprising that many people are interested in the question “how can you turn a bicycle into an electric bicycle?” The electric engine is quieter, does not emit harmful exhaust gases into the atmosphere, and does not heat up as much as its gasoline counterpart.

In the case of a homemade electric bicycle, the role of the engine can be played by a car starter, a screwdriver, or any other power units available on the farm. Along with the electric motor, an important component of the already converted vehicle is the controller (or regulator), the task of which is to accelerate the moped bicycle under optimal operating conditions of the power plant. To start moving, a very small current is supplied from the controller to the motor, due to which the motor begins to rotate smoothly. In a braking situation, the regulator recovers the energy of movement into an electric current that powers the battery. The battery is practically the same as a fuel tank, but much more environmentally friendly. It often consists of a matrix and batteries connected to a specific circuit.

The simplest homemade electric bicycle includes only a motor and a battery. After installing the motor, voltage can be supplied to it using a conventional switch. However, you should also be aware of the impracticality of such an approach, because, having a powerful power plant, it is somewhat more difficult to take off in such a vehicle, and this can lead to an accident. It is better to use a low-power unit that can provide a slow start to movement, even if it does not accelerate to serious speeds.

DIY motorbike from a chainsaw

Not every happy owner of a bicycle is delighted with the need to pedal and waste his energy. A motorized bicycle is more convenient and less expensive in terms of power.

Making a bicycle with a chainsaw motor with your own hands is not as difficult as it seems at first glance. For this you will need:

bike;
a saw with a gas engine power of at least 2000 W - this indicator will determine whether it can start moving. As practice shows, the engine power is 2 hp. It is enough for a motorbike to reach a speed of up to 40 km/h;
reservoir for the future fuel tank;
cable from an old bicycle;
a handle to allow you to adjust the throttle;
bolt ties, nuts and other small consumables for creating fasteners;
connecting elements for creating a connection between the wheels and the engine.

The process of installing a chainsaw engine on a bicycle is as follows:

we assemble the drive shaft - remove the rear wheel tire and install a tire with a diameter of up to 2.5 cm. This equipment will help to adjust the engine speed and, like a gearbox, reduce the number of revolutions;
We use electric welding to weld a stand from the corners - it will help install the engine from the chainsaw;
alteration of the clutch - you can use a centrifugal one from a factory saw, connecting it to the wheel;
we adapt the gas tank - it can be located next to the engine, or on the frame;
we attach the wire from the engine ignition system to one of the bicycle handles;
attach a cable from the carburetor to the gas handle so that throttle control is simple and quick;
We equip the motorbike with protective equipment: mirrors, a flashlight, and proceed to testing a homemade bicycle from a chainsaw.

As you can see, installing a chainsaw motor on a bicycle is not so difficult.

How to make a moped from a chainsaw?

For this you will need:

a motor from a working, powerful saw (in our version, this is the “Friendship” model);
2 wheels from an old bicycle;
pipe with a diameter of 2 cm (metal);
cable;
bicycle sprockets; as well as forks;
old spare parts from a motorcycle - a ready-made fuel tank, a headlight, and, if desired, a seat, although this can also be made with your own hands;
steering part;
gas lever.

The process of creating a moped looks like this:

we cook the frame to which we connect the wheels from the bicycle, forks, as well as a gas tank and a lantern;
we adapt the motor - the composition of the installation will depend on the configuration of the frame;

screw on the gas tank and battery;
we check that the newly installed elements do not dangle;
We make a chain drive - it will allow the wheels to receive the torque of the motor and move. You can use a belt instead of a chain pulley. But we must not forget that its wear will be noticeably higher;
we set up the ignition system - we connect the battery and brake lever to it;
adjust the exhaust pipe.

The assembly process is complete: you can start testing the moped.

Do-it-yourself chainsaw go-kart: step-by-step assembly

Among the possible equipment options, homemade go-karts made from chainsaws have gained enormous popularity - no less powerful and productive than their serial counterparts. Let's look at it step by step.

Preparatory stage

It begins with detailed drawings and design. We suggest that you familiarize yourself with the finished drawing, which will save time on design;

The proposed overall dimensions are suitable for a person of average height. For teenagers and tall people, the design should be adjusted to their individual parameters. For teenagers, you can use a different scheme presented below.

Collecting the design base

This is a chassis, the manufacture of which will require:

square pipes (up to 10 m);
steel pipes;
thick steel plate;
equipment for blocking the bottom;
armchairs.

The process looks like this:

The pipes are cut according to the proposed scheme and welded using electric welding.

This is what should happen after welding;

the front axle is equipped with plugs;
the rear axle is aggregated - it is welded to the frame itself in such a way that its rotation is ensured;
the bottom is cut out of metal or durable wood according to the drawing and fitted to the frame;
seat - in this case, you don’t have to mess around and take a ready-made one from an old kart or car.

Karting equipment with motor

remove the motor from the chainsaw;

We make a base for the motor - from a steel plate and a corner. Its pulley must coincide with the last frame structure;
screw the pulley;
we take 2 metal rods, which we bend at a right angle - this will be the kart steering wheel drive;

adjusting the brakes - it is desirable that the braking applies to all 4 wheels. Don’t forget about the brake pedal: pressing the brake with your hands will be very inconvenient;

we equip the go-kart with wheels – small-diameter wheels from an old racing car will do;
we set up the ignition - connect it to the throttle valve and the gas handle;
reliability control, assembly and testing of the finished unit.

Go-karting is a luxury for the average person, but with the help of available tools you can create a budget version of it - a go-kart with a chainsaw engine.

An equally famous homemade product that the domestic “Kulibins” learned to make. To recreate it we will need:

a scooter designed to support the weight of the person who will operate it. It is desirable that it initially have a manual braking system. The pneumatic wheelbase of the scooter must be durable;
a chainsaw from which the engine is removed - medium and high-power models are suitable.

The process of assembling a scooter looks simplified compared to previous homemade products:

First, remove the motor base and secure it to the back of the scooter frame. Make sure that the motor and wheel sprockets match;
we attach a manual accelerator with ignition of the chain saw - this way the operator can control the moving process;
If necessary, the scooter is equipped with a brake pedal, but in most cases, the lever for manual control of the scooter is enough for its full operation.
testing a scooter made from a chainsaw - if it is working properly, the new motorized device is ready and can be used.

Homemade children's ATV from a chainsaw

The last homemade product that we will look at will be dedicated to ATVs. In fact, to assemble an ATV you need similar materials as for a go-kart or tricycle:

engine from an old powerful and working chainsaw;
gearbox – increases engine thrust and takes over its operating speed;
ATV frame – it should be stronger and more stable;
the driver's seat is good if you have an old moped seat: a teenager will be more comfortable in it than in a bulky car seat;
wheels with rough tread, diameter of at least 34-35 cm each. This will improve the cross-country ability of the ATV and make it similar to an SUV.

If desired, the prefabricated structure of the ATV can be improved to perfection with shock absorbers: the maneuverability of the ATV will increase, and the operating stroke will become smoother.

Homemade vehicles are cheap, but not always reliable. They can only be used in strict compliance with all safety regulations.

Survival ideas: what you can do with your own hands from an ordinary chainsaw

This tool is convenient because it does not depend on the current source. You can work with it away from home. If you suddenly need a pump, a generator, a snow clearing device or an ice ax - a chainsaw will become the heart of any homemade machine. This way you will not only save money, but also get truly powerful and reliable equipment. Based on a 4-8 liter gasoline engine. With. you can build a home sawmill, a snowmobile sled, a generator for lighting, and even a cultivator. Let's look at the most popular homemade chainsaws and their manufacturing technologies.

Powerful chainsaw snow blower

Owners of suburban areas rarely enjoy heavy snowfall. At such a time, they have one main concern - to clear the driveways and passage to the house, clear the snow from the parking lot for the car and make their way to the exit to the highway. Not everyone has the strength and time to work with a shovel. That's why snow removal machines are very popular during the season.

But such a tool costs at least 30,000-35,000 rubles, and not everyone can afford it. What's in technical specifications is this a device? Still the same gasoline engine with a capacity of 5-8 liters. With. And if this is so, it means that the power of the chainsaw is theoretically enough for a homemade snow blower. The design of the snow blower is simple, pay attention to the diagram:

And now a small master class on making the device:

Image	Description of work
	The main shaft on which the shovel will be mounted will require metal stands. In this case, racks from a VAZ 2110 were used. They need to be welded into one piece using a metal coupling.
	For the drive you will need a sprocket from a motorcycle. It is welded into the shaft.
	The screw will require two sheets of metal rectangular shape and spiral sections. All this is cut out of durable metal with a thickness of at least 2 mm.
	The blades and spirals are welded in mirror image to the shaft.
	The shovel body is made of metal with a thickness of at least 1 mm. The shaft is mounted inside on automotive bearings.
	In the upper part of the body you need to make a hole for the snow discharge pipe.
	A movable cover should be installed on the snow discharge pipe so that the flow direction can be adjusted.
	The saw sprocket needs to be replaced with a motorcycle front sprocket. To do this you will have to bore.
	The engine itself must be mounted on a frame with rubber pads for shock absorption.
	To fix the steering wheel, you should make a strong stand from a steel pipe.
	The ignition and speed control system can be taken from a moped or motorcycle.

After assembling the main part, all that remains is to install the skis and fuel tank on the structure. The entire structure as a whole will weigh no more than 35 kg, so even a fragile woman can operate it.

How the entire device will ultimately look like this:

DIY universal snowmobile made from a chainsaw

Winter fishing or hunting is a favorite pastime for many. You won’t get to the treasured lake without a snowmobile, and running through the forest after game in waist-deep snow is no fun. Such a “toy” costs a lot - from 80,000 rubles. And again the chainsaw will help you out. What you need to prepare: a suitable sled with skis or tracks. The sled itself can be welded from a steel, or better yet, an aluminum corner. The lighter the design, the faster it will run. As a basis, you can take the device of a children's snow scooter on three skis according to this scheme:

The impulse for movement of a self-propelled self-propelled chainsaw is transmitted by tracks with hooks that push the sled forward. You can replace the tracks with a spatula with 7-8 blades; it is installed under the seat. The principle of installing the engine is the same as on a snowmobile - with a drive and gears from a motorcycle or moped.

You can use “Friendship” or more as an engine for a chainsaw snowmobile modern models, for example, "Calm". The steering wheel will come from an old bicycle, the motor control is output to it, or, if possible, immediately adapt the design from a moped - all the controls are ready there.

Brakes on snowmobiles were invented by cowards. But in fact, with a chainsaw engine, it will not develop dangerous speed, so you just need to let off the gas. Don’t get your hopes up, such a product will not be registered by any traffic inspectorate. So you can’t drive it on roads. But you won’t have to pay tax or undergo a technical inspection. For driving in the dark, do not forget to place a flashlight on the structure.

Homemade sawmill from a household chainsaw

In private households, construction never stops. I rebuilt the house - I planned a gazebo, finished the gazebo - I needed a garage, a fence, a shed, a doghouse. And so on ad infinitum. If you don’t have extra money, the cheapest option is to buy round timber and cut it into boards yourself the right size. A home sawmill can be built from the same chainsaw.

Image	Description of work
	We replace the standard nuts with special fasteners, they are bored out of a hexagon.
	On the sawing table, on a metal pipe, we install a movable coupling with a platform for attaching the saw.
	The thickness of the board is adjustable using movable racks. The higher you raise the racks, the thicker the board will be.
	All that remains is to secure the saw to the movable coupling using hexagons and work.

A primitive sawing device can also be made right at the site of tree felling. To work, you do not need to change the design of the unit; you just need to make a small device for the chainsaw that guides the movement of the tire. See how to do it:

Do-it-yourself ice drill from a chainsaw: diagram and practice

They say that you can’t pull a fish out of a pond without effort, but in winter I would like to limit this effort to twitching the jig. An avid fisherman is never limited to one hole.

But if the ice is 0.5 m thick, you will spend most of your time drilling, losing strength and mood. An ice drill will help you cope with this task quickly and effortlessly. Let’s see how much such a gadget costs: from 8,000 rubles. Why buy it if you have a chainsaw at hand? To make an ice drill, you will need an old electric drill - we will use it to make a drive. How to make an ice screw from a chainsaw with your own hands:

Image	Description of work
	An electric drill will require a working gearbox.
	You need to make such a tool from a part of an armature from a drill, a bushing and a 27 head. It will directly transmit rotation to the drill.
	One more element needs to be made with your own hands from a piece of metal and a pipe. This is a gearbox mount.
	The mounting structure is fixed to the saw using two bolts.
	This is what a gearbox with a bushing mounted on a saw looks like.
	A drill is inserted into the sleeve. In the future, a drill tube is placed on it and secured with a bolt.

Important tip! The key to successful operation and safety of the tool is the presence of a guide for the movement of the drill. Many people neglect this part of the design, and as a result, the drill breaks within the first minutes of use.

How the homemade design will work is shown in the video:

Do-it-yourself motor drill from a chainsaw

A motor drill is designed on the same principle as an ice drill. The only difference can be in the nozzle. In excavation work, the speed of rotation of the spiral should not be too high, so in a homemade design it is necessary to provide for speed control and simple shutdown.

DIY boat motor from a chainsaw

If you compare the cost inflatable boat and motor, it turns out that the boat is at least twice as cheap. The simplest gasoline outboard motor with 4 horsepower will cost 40,000 rubles. Expensive, to be sure. But the PATRIOT PT 6220 chainsaw with a power of 4.35 hp. With. – only 8,900 rubles. The power is the same, but the cost of the motor is five times cheaper! And what, tell me, is the point in purchasing an expensive boat engine?

Manufacturers of chainsaws have long clarified all these points and quite officially produce all sorts of attachments for them - from a drill to a drive with a propeller. The price of a boat attachment is 5,000−6,000 rubles. At the same time, there is no need to make significant changes to the design of the saw, which means that after fishing you can easily change the attachment and cut wood for the fire. Now about how a homemade boat drive works:

Image	Description of work
	Remove the bar and tension device from the saw.
	The lower part of the stand with the screw is made of a gearbox from a drill, a cone from a lawn mower, an oil seal and the screw itself.
	The pipe with the stiffener is made of aluminum.
	To secure the motor to the transom of the boat, we use a clamp. A platform for fixing the engine is welded to it.
	To connect the propeller to the motor, the author of the project uses a coupling made of polyethylene resin.
	The platform with the motor is movable, its movement is controlled by a handle. The power control is also located on it.
	The saw is installed in such a way that the sprocket fits into the coupling, and standard bolts fix the motor on the platform.
	For fastening you will have to prepare suitable nuts; standard ones will not work.

And now material about how this device works in practice:

How to make a moped from a bicycle and a chainsaw

This homemade chainsaw “Friendship” is the most popular of the options that you can make with your own hands. The one on a moped is always the first guy in the village, so many craftsmen start with just such a device.

Important! The design of a bicycle with a chainsaw engine must be especially durable. If this is not the case, reinforce the frame with additional posts.

A driven pulley is installed on the rear wheel, and the engine is securely welded to the frame. How it will look like as a result in this plot:

The Friendship chainsaw moped is quite powerful, so be extremely careful and don’t forget about the traffic rules!

Continuing the theme: do-it-yourself karting using a chainsaw

Trainers of young karting drivers know that more than one engine will burn out during the training process. The problem is that the child driving the car gets lost at speed. For this reason, to start training, a training go-kart with a walk-behind tractor using a chainsaw is quite enough.

The structure of a go-kart is primitive: a frame, a seat, a steering wheel and, in fact, an engine. The principle of installing the engine is the same as on a moped, the only difference is in its location. This is what it looks like:

In such a go-kart, children can race without risk on a track adapted for this purpose, and the speed will be quite decent - up to 80 km/h.

DIY chainsaw generator

Among the tools for survival in any conditions, the generator is far from last place. What to do if the electricity suddenly goes out at your dacha, and not only will you be left without light, but the heating will stop working without a pump. To protect yourself, it is better to prepare the simplest generator from a chainsaw in advance.

Use a bicycle gear to transmit torque. In this case, the saw should operate at minimum speed.

Here's how it works:

Winch from a chainsaw

A winch is often needed on the farm: it is useful at a construction site for lifting building materials, pulling vehicles out of impassable spring mud, and in many other unforeseen situations. Again, a chainsaw will help mechanize this device.

There are ready-made attachments for sale - winches. They work this way:

But you can make a simple device with your own hands. You will need to make a strong metal frame to which the motor will be attached, and mount the gear shaft.

DIY petrol cutter from a chainsaw, or How to make an angle grinder: video

A petrol cutter is the same grinder, independent of an electric drive. Agree, a tool is necessary in the household. To make it, you will need a grinder assembly, a fairly powerful chainsaw, a belt and a pair of tires. How to make an angle grinder from a chainsaw:

The advantage of the resulting tool is that it is completely autonomous and has good power. Perhaps it surpasses in its characteristics any factory electric grinder. You just need to keep in mind that the device is dangerous and requires a very careful approach. The most common problem is a burst disk; its fragments can cause serious injury. Therefore, working with such a tool without a protective casing is strictly prohibited.

Toy for adults: radio-controlled car made from a chainsaw

This toy is definitely not for children. It's hard to say what practical applications might be found radio controlled car from a chainsaw, but its creators were hardly looking for it. For keen modellers, a full report on the device:

Homemade chainsaw "Ural"

Why is it most often possible to find information about homemade products made from Ural saws? It's simple: a powerful, but heavy and noisy saw with reliable Soviet quality has remained out of use for many. It was replaced by light and comfortable models made in Europe and China.

“Friendship” and homemade products from this chainsaw with your own hands

“Friendship” is the ancestor of the “Ural”, and it has become a popular basis for homemade products for the same reason. “Druzhba” has a powerful 3-liter two-stroke engine. With. The device even has a chain brake.

“Ural” and “Druzhba” are distinguished by increased strength and endurance, like most engineering solutions from the times of the USSR. In addition, they are fueled with low-octane gasoline, and this is a significant saving. The only disadvantage of this technique is the weight.

Moped with gasoline engine

If you don’t want to refuel your car every day, and riding a bike is too tiring, then a homemade gasoline moped will be the ideal solution to your problem.

What do we need

We equip the frame

The bicycle frame becomes the main location for all the parts and elements of the future moped. In particular, the engine, gas tank and battery are attached to it using mounting clamps. The most successful option for their location is as follows:the battery is on the top tube, the engine is at the junction of the lower front and seat tube, and the gasoline tank is directly next to the engine.

We make pulleys and install them

The next step on the path to creating a moped with your own hands is the manufacture of pulleys - special transmission units through which the motor force will be transmitted to the rear wheel. The materials needed can be small wheels (the size of a CD) complemented by an external barrier. A prerequisite for creating pulleys is the strength of the parts used and the reliability of their fastening.

Installation of the specified parts on the bicycle is carried out in the following sequence:

1. The front transmission wheel is connected to the engine shaft.

2. The second pulley is attached to the hub of the rear wheel of the bicycle.

3. Then a belt is put on the pulleys, setting the tension force like a chain.

Note!The belt must adhere well to the wheels, since the accuracy of the transmission of force from the engine to the wheel depends on this. In the case when a chain drive is used instead of a belt drive, gears take the place of pulleys.

Motor connection

Interesting fact!Worldwide, there are approximately twice as many bicycles as cars and motorcycles. In addition, 50 million new non-motorized two-wheelers are produced annually, while only 20 million of traditional cars join their ranks.

Assembling a moped with a gas engine

Compared to the previous option, this method will allow you to get a more “advanced” vehicle that almost completely corresponds to a real moped.

What do we need

Preparing the frame

Note! If the selected engine is not fully operational, then it should be carefully rebuilt, replacing failed elements. You may not yet fully understand how you can make a motorcycle out of a bike, but the serviceable condition of all the elements used should not raise any doubts.

By the way, the power plant requires a separate place, and the best option would be a welded metal platform located at the bottom of the bicycle frame. The engine and gas tank are attached to it using metal fasteners. It is better to place the battery closer to the steering wheel, and connect the exhaust pipe to the bottom of the engine.

Create torque

Connecting the engine

Do you know?Cycling helps you stay in great shape. For example, an hour-long bike ride helps you lose 600 calories.

Creating an electric bicycle

If you don't like the idea of using a gasoline engine on a bicycle, then you can consider an alternative option for upgrading this vehicle using electric equipment.

Advantages of Electrical Equipment

Step by step assembly guide

There are a fairly large number of ways to assemble an electric bicycle, but the easiest way is to connect the drive to the tire. If you had a Soviet-built bicycle, then you probably came across a dynamo generator to connect the headlight. The same principle is used to connect an electric motor to a wheel. Of course, when using this method, the efficiency of the drive will be very small, but for testing a vehicle on electric power this is quite enough.

The second option on how to make a good electric bicycle with your own hands involves installing extra star on the left side of the wheel and mounting the engine with a star on the trunk. If we connect them with a chain, we get the simplest chain drive. However, as in the previous version, there will be mechanical losses, and the appearance is not particularly attractive.

Therefore, it makes sense to consider the third and most suitable way converting a regular bicycle into an electric bicycle. It involves the use of a special wheel motor, which allows you to get an electric motor for a bicycle with an excellent aesthetic appearance and high efficiency, which will make it possible to create a unique vehicle with your own hands. The motor-wheel differs from a regular wheel by the presence of a drive mechanism in the central part. It connects to the control unit using wires and makes it possible to create a front-wheel drive bicycle without changing the classic transmission.

If you have the desire and opportunity, you can install two motor wheels at once. The installation process involves the following steps:

1. Mounted on the carriage axle new star and a belt pulley;

2. Then a shaft with a drive pulley is attached to the seat tube;

3. The pulleys are connected to each other using a belt, and the shaft is connected to a power source through wires;

4. The wires from the battery are pulled to the switch on the steering wheel.

Note! It is better to place the battery on the lower front tube of the frame or on the trunk.

To summarize all of the above, it should be noted that it is still possible to assemble an electric bicycle in the “do-it-yourself” style, but for this you need to find all the necessary parts and spend a little time and nerves. The operation of such a vehicle itself should not be accompanied by any difficulties, of course, except for the surprised looks of passers-by, which, however, is rather a compliment to you.

Interesting to know! When mounting a bicycle, most people approach it from the left side, crossing their right leg, which is explained by the presence of a chain and sprocket on the other side. The habit of placing the chain with right side came from horse riding, since the sword, located at the rider’s left hip, made it difficult to sit on the right.
