Moped made from a chainsaw. Assembly and drawings. Tips and tricks

A DIY chainsaw motorcycle is an option for creating a lightweight vehicle for those men who have an engineering mindset, love technology and are always ready to invent something new. This is also an excellent option for those people who do not want or cannot spend a lot of money on a car, motorcycle or moped, but at the same time have an old chainsaw, a bicycle and are ready to buy some spare parts.

The article will give detailed recommendations on how to make a motorcycle with your own hands from a chainsaw.

Chainsaw moped

At first glance, a moped and a saw are absolutely incompatible things that cannot interact in any way. But this is wrong, and numerous craftsmen have proven that making a moped from a chainsaw is quite possible. But there is little to be done; this unit also drives and transports its owner. The speed, of course, is not very fast, but it’s still better than walking. You can use a bicycle as the basis for the design or do everything completely yourself. The bike motor amazes with its endurance, but this is what everyone expects from time-tested saws.

The older generation is familiar with self-propelled structures in the form of a bicycle with a motor. It is difficult to classify this equipment as mopeds, but they no longer fall into the category of bicycles. A kind of “middle link”. A significant advantage of such a unit is low fuel consumption and the ability to drive without a license. You can’t ride it on public roads, but you can drive along rural streets and alleys.

The frame has undergone changes, which have been extended to accommodate bicycle or other wheels, depending on what is available. A fuel tank is also attached, a motorcycle seat is installed, and a headlight is attached for driving in the evening. A water system has been developed to cool the bicycle motor. This was done to prevent the engine from overheating quickly and losing power.

What will be needed for production?

At the initial stage it is necessary to select devices:

• Chainsaw with a power of up to 3 kW, which corresponds to 5 hp.
• Bolts and nuts from 14 to 19.
• Special mounting brackets.
• Bike.
• Motorcycle chain.
• Reservoir for fuel tank.

The chainsaw engine power of 2 to 3 kW allows the moped to reach speeds of up to 40 km/h, which is quite enough for a light two-wheeled vehicle.

And a mechanic's tool:

• Wrenches from 14 to 19.
• Drill.
• Bulgarian.
• Welding machine.
• Vise.

If it is not possible to use a ready-made bicycle, then its components are needed: sprockets for the chain, metal profile tubes for assembling the frame of the future moped. In addition, you will need to purchase a motorcycle brake system, side lights, and a flashlight.

Obviously, working with such a tool on the listed devices is accessible to ordinary people who are not afraid of working with a mechanic’s tool and an angle grinder, and also have basic skills in working with electric welding.

What details are needed?

In order to assemble the motorbike structure you will need the following materials:

1. chainsaw motor
2. bicycle wheels 2 pcs.
3. tank, headlight, seat from a motorcycle or other suitable unit
4. spray paint cans 4 pcs. and masking tape
5. metal pipe 16-20 mm.
6. cable
7. chain
8. cycling stars
9. front and rear bicycle forks
10. axis
11. hose
12. plastic bottle
13. IV
14. steering wheel
15. throttle handle

It should be noted that on the modern market there are ready-made kits that include all the necessary parts for making homemade products. But the question here is price. If you want to save money and use unnecessary parts lying around in the barn, you will have to try on your own.

Transmission.

I found a wheel from a scooter and then the idea came to me to put a star there, I had a hub from an alpha moped collecting dust in my garage, I slightly adjusted the hub from a moped, it fit like a cast one, drilled the holes, tightened the hub, the star does not hit and holds well. I set the driven sprocket to 41 teeth.

I took the drive sprocket with 9 teeth and the gear ratio was 4.5.

Assembly principle

The first thing that attention is paid to is the design of the frame, which is made of pipe and on which the power unit will subsequently be placed. Then the tank, headlight and wheels are installed. If you are using old parts, you must first clean them of rust. This is especially true for seams. After the initial stage is completed, the frame is covered with several layers of paint. Be sure to dry each layer thoroughly to avoid corrosion. As a recommendation, it is best to use spray paint to avoid smudges. You can paint not only the frame, but also the wheels, after sealing the rims with masking tape.

Moped from chainsaw Druzhba-4

After all the parts are dry, you can begin installing the chainsaw engine. Make sure that the motor is well installed and secured. Without a cooling system, such a bicycle motor will overheat after 30 minutes of operation, so it is advisable to make a water cooling system. The homemade device looks like this. 2 flexible tubes are connected to the plastic bottle. One is attached in the upper part for air intake, the other in the lower part and through it, using a drip system, water flows to the engine cylinder head. The result is simple homemade drip irrigation and effective cooling.

Tips and tricks

Many users insist on paying attention to how the belt is held on the wheels. The degree of its fastening affects the transmission of force from the engine, and, consequently, the driving process. The chain is a more reliable and durable part, but do not forget that when using a chain on a homemade moped, gears are used instead of pulleys.

The engine that you removed from the chainsaw should be in full working order. Otherwise, spend a little more time assembling the moped yourself and rebuilding the engine. Try to fix failed parts or completely replace them with new ones.

Power station

For a mobile power plant with a power of up to 5 kW, there is a time-tested solution: a homemade generator based on a motor from a Druzhba or Ural saw. They are actively used on expeditions and in remote logging operations. The device includes a steel frame welded from a corner, on which an engine, a generator and a waterproof electrical distribution box with sockets for connecting electrical equipment or an extension cord are mounted. Through the gearbox, torque is transmitted to the generator shaft.

For low-speed generators, there is an option for a homemade power station with a belt drive. This design is smaller in size.

Preparation

To make a go-kart you will need various materials. Karting is a means of transport that covers a long distance in a short time. Karting can participate in competitions, it can be driven on uneven roads, in rural areas, where large equipment cannot pass. The preparatory stage begins with creating a diagram of the future structure.

A drawing of the karting should be drawn up taking into account the dimensions, which should correspond to the height of the person. For teenagers, the device can be made to individual specifications. After choosing the sizes, you need to assemble the main base. To make a karting structure, you will need the following materials and tools:

• chainsaw;
• square pipes 10 m long;
• round steel pipes;
• durable steel plate;
• gearbox from an old car;
• bottom plugging equipment;
• driver's seat from a kart or passenger car.

Why does a bicycle need a motor?

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.

Bicycle with motor

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.

: Attach the rear sprocket

Most kits come with a sprocket that you attach to the rear wheel. This sprocket is connected to the engine and is the main drive for transmitting torque to the rear wheel. The most important thing to remember is that the sprocket must be installed tightly, there should be no vibrations, otherwise the chain may jump off while driving.

A fanatical measurement process is not required, but it will not be unnecessary either.

Do-it-yourself bicycle (moped, go-kart, scooter, ATV) with a chainsaw motor

Modern gardeners are increasingly experimenting with the gasoline-powered tools at their disposal. Mainly, a household chainsaw is used for this. Very often, its engine becomes the basis for the manufacture of simple but very useful homemade products for self-assembly. For example, from a suitable chainsaw motor you can make a bicycle, moped, go-kart, scooter and a host of other means of transportation.

Homemade mopeds made from chainsaws will be useful for moving over rough terrain. They are also often used for driving in urban areas, where a lot of traffic accumulates. The small dimensions of mopeds give them the opportunity to easily overcome traffic jams and pass small obstacles.

For assembly you will need:

• engine from a gasoline tool. The speed of the moped depends on its power. When choosing a motor, you need to start from the fact that an internal combustion engine with a power of 2 liters. With. enough for driving at a speed of no more than 40 km/h;
• tank for refueling the moped. It is best to choose metal tanks or containers made of hard multilayer plastic;
• gas lever and standard bicycle cable - they are needed to adjust the throttle position;
• switch and wiring - required for installation and connection of the standard motor ignition system for a moped;
• parts for making the bracket, nuts and bolts - needed to install the motor on the support frame;
• belts, chains and pulleys - they will make it possible to connect the drive wheel of the moped to the engine from the chainsaw.

Assembling a moped from a chainsaw should be done in the following order:

1. First of all, you should calculate the transmission of force from the engine to the wheel. To do this, you will need to determine the required gear ratio for the moped. If it is too small, the internal combustion engine will not be able to transfer its force to the moped wheel. In the case of an extremely high gear ratio, the engine will operate at very high speeds, and the moped will move too slowly. There is a certain example, based on which you can determine the optimal gear ratio. If the power of the motor used is 1.8 liters. s., and its maximum speed is 12500 rpm, then the optimal gear ratio for the moped will be 1:26;
2. The simplest method is to transfer force from the standard pulley to the moped wheel - directly from the engine. You can also equip the rear wheel with a pulley or sprocket, which must be connected to the motor with a chain or belt;
3. Next you will need to equip the bike with a clutch. The easiest way is to use a standard centrifugal clutch from a chainsaw. In some cases, chainsaw owners connect a standard moped clutch to a bicycle ratchet. After this, the mopeds accelerate and move by inertia, which makes it possible to save fuel and engine oil;
4. The next step is to install the gasoline tank. To make the device safe, the tank will need to be placed on the bicycle frame, connecting the tank to the engine using a fuel hose;
5. Then you will need to install the ignition. To do this, the standard wire of the unit must be stretched from the motor to the handle of the bicycle. The latter must be equipped with a switch that will make it possible to turn off the internal combustion engine of a homemade moped.

To be able to control the motor, a homemade moped can be equipped with a gas handle. A part from a mountain bike is suitable for this. You need to remove the lock from the handle - this will give it the opportunity to move smoothly in any direction. After this, the stock cable will need to be connected to the factory throttle valve.

Three-wheeled bike with a chainsaw engine

Dear visitors of the site “Visiting Samodelkin”, from the material presented by the author you will learn how you can independently make a three-wheeled mini-bike with an engine from a Ural chainsaw with a minimum of funds, so let’s go)
This three-wheeled mini-bike is the brainchild of one very good man and his name is Gainetdin Bulatov from the city of Pyt-Yakh, or simply Gennady. The author made the three-wheeler especially for his beloved grandchildren; Gennady has three of them)

The heart of the mini-bike is the engine from the Ural chainsaw; according to the author, it was lying abandoned in the garage because he uses modern saws. This engine is well suited for a mini-moped and has enough power to push a child around.

The frame is welded from a half-inch water pipe, the wheels are from a garden wheelbarrow, the axles are from the same, the small drive sprocket is from a D-6, the large driven sprocket is from a bicycle, the chain is also a bicycle chain. The throttle and brake cables are mounted on the bicycle handlebars. The rear axle is mounted through bearings at three points and is driven by transmitting torque from the engine through a chain drive from a small to a large sprocket.

The wings are also homemade and made of metal from an iron barrel. There is a small glove compartment under the seat where you can store and transport wrenches and a chainsaw starter.

So, let's look at what exactly the author needed to assemble a three-wheeled mini-bike?

by-step process of assembling a mini-bike with an engine from a Ural chainsaw with your own hands.
As mentioned above, Gainetdin created this mini-bike for his grandchildren in order to instill in them a love of motorcycles from a young age. A three-wheeled moped is very convenient in terms of stability, just like a bicycle in principle, and the child quickly gets used to riding such a bike. It’s clear that children love their grandfather very much for his invention and enjoy riding in the yard of the house (under the supervision of adults, of course)

To start the assembly, the author purchased 3 wheels from a garden wheelbarrow at a reasonable price.

Then I made the rear axle and prepared the bearings.

Next is fitting and test assembly.

In order to reduce the noise of the exhaust pipe, a muffler was additionally made from a pipe with 3 partitions inside, which helped reduce noise.

The seat is made of plywood and foam rubber trimmed with substitute leather, attached to the frame on hinges, and under it there is a trunk where you can put a tool and a starter.

Installed the gas tank and connected the gas line.

Torque is carried out by chain transmission.

The rear axle is attached to the frame via bearings at three points.

The gas and brake cables are routed to the steering wheel. The bike's fork is also homemade.

Asterisk from D-6.

This is such a cool bike

We also recommend watching a video of rides on a mini-bike

The creator of the three-wheeled mini-bike is Gainetdin Bulatov from the city of Pyt-Yakh.

As you can see, in order to make your children and grandchildren happy, you don’t have to buy expensive imported toys that he will play with, break and throw away, but such a bike will give happiness and joy to a little boy and respect among his peers and not only) Well done Gainetdin.

How to work with a homemade device correctly

The safety rules when working on such devices are the same as for any woodworking machines. The operator and bystanders must not approach the cutting blade. It is undesirable to work tired, with reduced reaction. Common sense should be used. Clothes should be buttoned and pulled up, without loose hems that could get caught in the chain.

If there is a wide spread of sawdust, you should wear safety glasses. When working for a long time, it is advisable to wear headphones to protect against noise.

Technical features:

• Do not put pressure on the cutting unit. The saw advances as sawdust is removed from the cut, without effort.
• Do not use chains with dull teeth or tires with worn grooves.

Frame.

I used an old bicycle as a frame, sawed off the steering column and the back of the bicycle - this was the basis for a moped. I set the motor straight so that the chain wouldn’t warp and it wouldn’t fly off. I welded the rack from the gearbox, then installed the motor and near the ears of the snail, I welded a corner, drilled holes, and secured the motor with an M6 bolt.

Then I simply welded my frame at random without drawings or dimensions, and installed the seat from an old AIST bicycle. I bought a fuel tank from Riga 13 and all that remains is to install the brakes and paint it.

Helicopter

This type of homemade product is considered complex and therefore has not been implemented to date. She is in the dreams of enthusiasts, in invented stories. One of them claims that back in the USSR, a prisoner who understood mechanics made a helicopter with a chainsaw engine and was able to escape from the colony.

Making a homemade helicopter requires, unlike a snowmobile, outboard motor, bicycle, grinder and even a snow blower, more complex engineering calculations. They also show that one, even powerful, engine is not capable of lifting such an aircraft into the air. At least 4 motors are required, moreover, forced and working in concert at the highest possible speed. But it is difficult to implement this with chainsaw engines in practice.

Winch

A homemade winch will be an excellent help in construction and lifting loads to a height, dragging a cut tree, rescuing a car stuck in a puddle, or pulling a boat out of the water. The thrust of such a homemade winch depends on the engine power and the gear ratio, and can reach one and a half tons. For specific applications, the unit is equipped with additional components: blocks, pulleys, hooks, sling belts and anchors for attachment to the ground or to a tree. To make a winch from a chainsaw with your own hands, you will need to weld a strong frame on which to place the engine, gearbox and drum with a stopper. The frame is provided with holes and lugs for various methods of attaching the device to the ground, a wooden or concrete foundation, or to a tree trunk. The drum can be taken from an old winch, or you can make it yourself according to the drawings.

You should follow the safety rules when carrying out lifting and rigging work:

• Cables, hooks and slinging accessories must be strong and periodically tested to tensile strength.
• The stopper must securely fix the drum and prevent spontaneous unwinding of the cable under load.
• When lifting heavy loads, the winch must be secured to a permanent or temporary foundation, the weight of which must be five times the maximum weight of the load being lifted.
• It is strictly forbidden to stand under the load and in the area of ​​its possible scattering when falling, as well as to the side of a tensioned cable when moving objects horizontally.

What is included

To convert your bike into an electric bike, you need the following basic components (they are included in every kit):

• motor-wheel. This is the heart of the electric bike, the electric motor. You simply exchange one wheel for another;
• accumulator battery;
• battery fasteners, wires;
• control panel or console.

In order for disappointments not to be endless, you need to know that a fairly fast and long ride is only possible with a power of about 1000 W, that is, 1 kW. If you decide on the price, then on average you will have to pay 20 thousand rubles for a wheel motor with a kilowatt engine.

An electric bicycle can be made with a more capacious or less capacious battery. So, a battery with a capacity of 18 A/h will cost 30 thousand rubles.

Therefore, it is not recommended to buy cheap electric kits that can only last a short time on a flat road. They develop a power of 250 - 35 W and can be considered “children’s”.

Motor drill

During the construction season, a motorized drill made from a chainsaw will do an excellent job of digging holes for posts or screwing in screw piles, and in winter it will delight ice fishing enthusiasts. The design of a homemade motor drill will require a speed reduction gearbox, since piles should be drilled and screwed at a speed of 30-60 revolutions per minute. It is better to take the auger from a ready-made motor drill made of good steel. An auger for a hand drill or a homemade one made of simple structural steel will not last long with active use.

Compressor

The craft consists of using an air blower from some device and using a chainsaw motor as its drive. If it is from an air conditioner, then you can make a device for quickly inflating the wheels of a car.

The procedure for making a compressor from a chainsaw:

1. Make a mounting plate from sheet metal. On one side, 2 holes are drilled through which it is attached to the chainsaw instead of a tire. On the other hand, a compressor is placed.
2. A coupling and pulley are installed on the supercharger drive shaft.
3. Place the second pulley on the output shaft of the saw motor.
4. A belt is placed on the pulleys to transmit rotation.
5. The inlet pipe of the supercharger is equipped with an automobile oil filter with oil residues. Air through it is sucked in with oil particles, which reduces overheating of the compressor during operation.

To start the device, turn on the chainsaw motor. When it picks up speed, the coupling is activated and the supercharger starts working. A hose is connected to its outlet pipe, through which the car’s wheels are inflated.

Warnings:

• Before you go to the race track, make sure that your homemade kart is in good working order, as parts may break or become detached;
• Always wear protective equipment such as a helmet, pad, etc. before riding a go-kart;
• You should not accelerate in a homemade go-kart to a speed of more than 30 km/h. This may cause a mechanism failure or breakdown of parts, since this model does not have high-tech design and engineering solutions;
• remember! A go-kart is not a real car. Under no circumstances should you drive it on the road.

Cultivator

The device simplifies the processing of vegetable gardens and beds. If they are of a small area, a DIY chainsaw cultivator has an advantage over branded products - it will save money on the purchase.

Making a homemade cultivator from a chainsaw starts with a frame. It is made in the form of a cube using 32x32 corners. An engine is attached to the transverse upper corners, which must have a power of at least 4 liters. With. Below it, a fuel tank is installed on brackets. The front vertical struts are equipped with supports for the intermediate shaft, which are attached to the longitudinal corners.

This placement of components and elements allows you to obtain the center of gravity of the walk-behind tractor above the supporting surface of the wheel. If it is necessary to adjust it, use a metal weight, which is placed in the front part of the frame.

For manual control, crossbars are installed using pipes with a diameter of 30 mm. Rubber-coated rollers are used for the wheels of a chainsaw motor cultivator, and a chain drive is used to rotate the intermediate shaft. To do this, sprockets are installed on it and the engine output shaft. Their size is selected according to the required gear ratio.
