How to make a moped from a friendship chainsaw and a bicycle. How to assemble a moped with your own hands from a chainsaw and available parts
At all times there were “Kulibins” who could make something truly innovative and useful out of seemingly ordinary things. If you don’t have any ideas in your head, and the desire to do something with your own hands doesn’t give you rest, then you can start with existing and practice-tested developments. Do-it-yourself chainsaw crafts are perfect for this. Especially for those who are not used to sitting with their hands folded, our editors have prepared a review with detailed photos and video instructions on how and what can be made from an old chainsaw.

What and how you can make from a chainsaw with your own hands
A chainsaw is a universal unit. The size of the tool is small, but the power of the motor allows it to be used for almost any purpose. The “rotary heart” will feel great when transplanted into an ice ax or any other device where an autonomous drive is needed. Let's take a closer look at some know-how.
How to make a snow blower from a chainsaw
If you have a chainsaw and parts from an old car, then you can start designing. Typically a rotary drive is used to drive the auger. This is a special shaft designed in a special way for collecting snow.
| Illustration | Description of action |
 | As the main shaft we use rods from the front pillars of the VAZ 2110, welded together. |
 | To connect the joints we use this coupling. |
 | These are sheets for welding screw blades. Size: 140×100 mm, traditional thickness: 2 mm. |
 | For the drive, you can adapt a star from the Voskhod motorcycle. The back of the part is welded with a prepared 5 mm metal disc. With a hole made to match the shaft diameter. |
 | This is what the parts looked like before. |
 | The auger blades are made from 2 mm metal sheet. To do this, a circle is cut out with a diameter of 300 mm on the outside and 220 mm on the inside, and stretched from the star to the blade. |
 | We prepare a frame from the same “two” and load-bearing strips with a radius of 160 mm. |
 | We bend the body from a sheet of 1 mm. We weld with the sidewalls. |
 | This is the screw we ended up with. |
 | The diameter of the hole for the snow ejector is 160 mm. For the turning mechanism, you can use a plastic pipe. |
 | But it is better to make the gutter itself from a galvanized sheet of 0.75 mm. |
 | We remove everything unnecessary from the saw, clean it, paint it black. Let's disassemble the saw star. |
 | We clean all the parts, center them, and weld the sprocket from the Java motorcycle. |
 | We place the chainsaw engine on rubber cushions. |
 | We place the frame for mounting the motor on shock absorbers. |
 | We paint the entire structure and do a test run. Everything is working! |
DIY snowmobile made from a chainsaw
To make a homemade snowmobile from a chainsaw, you will need some factory-made parts (for example, a gas cable to the steering wheel) and a children's snowmobile.
| Illustration | Description of action |
 | To create a snowmobile from the Druzhba-4 chainsaw, we will need a children's snowmobile. |
 | To create a caterpillar, take a 25mm polypropylene pipe, cut it into 20cm pieces, and cut it in half lengthwise. |
 | You can use an old car tire as a tape for the track. |
 | In our work we use MNS elevator drive sprockets. |
 | Next, in this way, using screws and prepared plastic pipes, we create our caterpillar. |
 | We begin to assemble the drum with the shaft. |
 | We attach the plastic stars and the “carpathian” driven by the moped. |
 | We take the tensioner rollers from the Ryazanets potato harvester. |
 | The next stage is to manufacture the track tensioners and the frame itself. |
 | We install the chainsaw on the frame, and now you know how to make a snowmobile from a chainsaw. |
 | We remove the plastic from the snow scooter and modify the frame, attaching the “motor dog”. |
 | The connections are fastened like a rear fork, like on a motorcycle, only without shock absorbers. |
Homemade sawmill from a chainsaw
Craftsmen offer dozens of different options on how to “adapt” a chainsaw for. Most often, such structures require welding of the frame to install the “carriage” under the so-called tires. Available tools are used as guides, for example, an ordinary ladder.
The most important thing is to weld the frame tightly, controlling yourself according to the level. A level and solid base will help avoid distortions and vibration during operation. Also consider at what distance and height the chainsaw will be mounted. The longevity of its work depends on this. Fastening the carriage too close to the working area will lead to clogging of the chain mechanisms and failure of the motor.
If you do not plan to cut large logs, you can make a manual version of the sawmill. More details in this video.
How to make an ice screw from a chainsaw with your own hands - diagrams
The drill is an indispensable thing for those who know how and love to work around the house: it is used in construction work, installing supports for the vineyard, and also in winter fishing to prepare holes.
To make an ice screw from a chainsaw with your own hands, you need a diagram and the following devices:
- Chainsaw motor.
- Chainsaw gearbox for drill.
- The drill itself.
- Metal pipe.
- Drill.
The most important thing is to select the correct gearbox for the motor and make the necessary calculations of the compatibility of their characteristics. The chainsaw motor may be too “spirited” for the simplified design of the gearbox.
The first thing that is important to do, if you put aside humor and approach the problem seriously, is to determine the dimensions of the drive shaft and select the correct mounting points for the drive gear. It is better to fix it around the perimeter with studs and dowels. This fastening will simplify the process of changing attachments in the future. If you do not have the skills of a turner, then a turner and our diagrams will help you make a special adapter for the drill auger.
DIY boat motor from a chainsaw
It can be expensive to buy a ready-made sample of a boat motor, but if you have an old motor from a Druzhba chainsaw lying around and you are friends with and, then making such a homemade product will not be difficult.
| Illustration | Description of action |
 | The clutch and tire are removed from the chainsaw. Only the shortened cross remains. |
 | We make a recess on the rod for this cross and install a bearing. |
 | We also install bearings at the bottom; the clamps are taken from a Soviet outboard motor. |
 | From the grinder we take a 250 gearbox, a propeller and a keel. Everything is secured to silicone with additional seals. Transmission lubricant is filled inside. |
 | And the water motor, with a slight movement of the hand, is placed on the base along the guides, and the structure is secured with standard nuts. |
Among the main advantages of the homemade product are high power, providing decent speed of movement on the surface of the water, and economical consumption of fuel material. In an hour, a homemade chainsaw consumes 1 liter of gasoline at a speed of 20 km/h.
How to make a moped from a chainsaw and a bicycle
To make it you will need:
- chainsaw;
- old hand winch;
- a rigid frame on which everything will be installed;
- two sprockets and a durable motorcycle chain to transmit torque from the saw motor to the gearbox.
Options for chainsaw attachments with a winch function: 
If you haven’t yet found a homemade option for yourself, read further in our editorial review of what else you can make from a “Friendship” chainsaw.
How to make a motor drill from a chainsaw with your own hands
Let's consider the option of assembling a chainsaw attachment using a part from a conventional drill.
| Illustration | Description of action |
 | We disassemble the electric drill and dismantle the working gearbox. |
 | We bore the armature from the drill, and from parts of the bushing and head we weld a structure that will transmit rotation to the shaft. |
 | We make the mount for the gearbox from a piece of metal and a pipe. |
 | The structure is fixed to the saw body using two bolts. |
 | This is what the finished design of the gearbox with bushing looks like. |
 | We insert a drill into the sleeve, it will subsequently transmit torque to the drill. |
It is made using the same principle from a chainsaw, only a plow is used as an additional accessory for it.
DIY petrol cutter from a chainsaw
However, such models will cost much more than a homemade attachment that you can make yourself.
| Illustration | Description of action |
 | We disassemble the electric drill, the main task is to remove the sprocket, which will be replaced by a pulley in the future. |
 | We install the pulley, bearing and plate. After this, we install the “original” clutch. |
 | In order to secure the piston at the dead center and facilitate the work of assembling and disassembling the pulley, you can use a regular lace with knots. |
 | Next, install the starter and close the lid; all you have to do is attach the nozzle with the disk. |
A homemade gas cutter is much more powerful than a grinder. It can be used for cutting large diameter metal pipes as well as grinding them.
Radio-controlled car with a chainsaw engine
If your child really wants a radio-controlled car, but he considers what is sold in the store to be a toy “for girls,” you can try to make a real racing car with a chainsaw engine.
| Illustration | Description of action |
 | We buy a piston like this and assemble the carburetor. |
 | They took a ready-made racing car as a basis. |
 | Our task is to make the drive and exhaust pipe and ensure that no stones or bolts get into the piston. |
Hello tinkerers, today we will look at how to connect a chainsaw to a bicycle, resulting in a moped. The author used a rather old but powerful chainsaw, this is the notorious Ural chainsaw. The author rebuilt the bicycle, made a safe frame, and also replaced the wheel spokes with stronger, reinforced ones. The homemade product is quite simple to assemble, we need to make a bicycle gearbox from bicycle parts and install everything on the bicycle. According to the author, the homemade product pulls excellently; as for the maximum speed, this remains unknown. If you are interested in the project, I suggest you study it in more detail!
Materials and tools used
List of materials:
- chainsaw "Ural";
- two driven and one driving sprocket from the bicycle;
- carriage with axle and connecting rods;
- bicycle chain;
- throttle handle and cable;
- chain tensioners for bicycles;
- pulley, spring (for tensioner);
- profile pipes;
- iron plates.
List of tools:
- ;
- ;
- vice;
- drill.
Homemade manufacturing process:
Step one. Gearbox
The working shaft of the chainsaw engine develops huge speeds, but we don’t need them, they need to be turned into lower speeds with high torque. We assemble the gearbox from a bicycle carriage, cut off the excess parts of the frame, and also cut off the connecting rods. Next we need a small sprocket from the rear wheel; it needs to be welded to the part of the axle where there is no sprocket. That's all, after this the gearbox will be ready.
To connect the saw to the gearbox, you will need another small bicycle sprocket; it needs to be welded to the chainsaw sprocket. We attach the gearbox to the body of the chainsaw, weld it to the persistent spikes of the saw, and also additionally strengthen everything with iron rods or other parts. We install the chain on the gearbox, start it, and check that the chain does not fly off. If the sprockets are welded too crookedly, the chain is likely to fly off frequently.
Step two. Driven sprocket
We will need a large diameter driven sprocket to obtain high torque. A drive sprocket from a bicycle will do; cut off the connecting rod from it. The author welds this sprocket to the part of the wheel where the foot brake lever is attached. As a result, the design of our bicycle remains almost unchanged; it can be ridden either by pedal or with the help of an engine. And if the motor power is not enough, you can always help with your feet.
Step three. Engine Installation
Let's start installing the engine, and we will install it on the rear trunk. Of course, one trunk cannot cope with the assigned loads, so we additionally strengthen the structure with profile pipes.
We install a chain on the bicycle that connects the gasoline engine and the rear wheel. Here the author had a problem, since the sprockets were welded crookedly, the chain kept falling off, and the chain turned out to be long. To solve the problem, the author made two dampers in the form of pieces of profile pipe. A chain tensioner was also made from a pulley from a generator, a profile pipe and a spring. After that the chain stopped falling off.
The author's engine is modernized; a carburetor from a scooter is installed on it. Thanks to this carburetor, the engine starts easier and runs faster. Once the engine installation is complete, you will need to install the gas tank in a convenient location.
Step four. Throttle grip
We install a throttle grip on the steering wheel, you can buy one in a store that sells spare parts for motorcycles. We run the cable along the frame and connect it to the carburetor throttle. After this, the homemade product is ready, you can test it.
The author tests the bike on himself, the author helps to move off with pedals, but in general the moped accelerates well. The only thing that remains unclear is how the author plans to brake, because instead of a brake lever we now have a driven moped sprocket. Hand brakes must be installed on mopeds.
This homemade product is ready, I hope you liked the project and found useful thoughts for yourself. Good luck and creative inspiration if you decide to do this again. Don't forget to share your ideas and crafts with us!
Dear visitors to the site “Visiting Samodelkin”, from the material presented by the author, you will learn how to make a moped yourself from a Druzhba chainsaw.
From Soviet times, many still remember such a miracle of technology as a bicycle with a motor, in common parlance a “hole” is the middle link between a bicycle and a full-fledged moped. The equipment is good, low fuel consumption, and you don’t need a license)).
The current generation is much more advanced in terms of modernization, improvement, restoration, and tuning. They remake factory equipment so that the designers do not recognize their brainchild))
So the author came up with the idea of making a moped from the Druzhba chainsaw, but so that it would not look like a homemade product, but would look stately and elegant. The master already had experience in creating such equipment and had a ready-made moped, on its basis this masterpiece was created.
The frame was extended to accommodate bicycle wheels, a tank, headlight and seat from the Minsk-103 motorcycle were installed. Water cooling of the chainsaw engine was developed and used, because after 20 minutes of operation the engine got hot, the power dropped and, as a result, the work stopped, and due to water cooling the moped feels great and doesn't get hot.
So, let's look at what exactly the author needed to create a moped?
Materials
1. engine from the Druzhba saw
2. bicycle wheels 2 pcs.
3. tank, headlight, seat from the motorcycle "Minsk-103"
4. 4 cans of paint and masking tape
5. metal pipe 16-20 mm
6. cable
7. chain
8. bicycle sprockets
9. bicycle forks, front and rear
10. axis
11. hose
12. plastic bottle
13. dropper
14. steering wheel
15. throttle handle
Tools
1. welding machine
2. grinder (angle grinder)
3. drill
4. set of wrenches
5. hammer
6. screwdriver
7. pliers
8. roulette
9. sandpaper
Step-by-step instructions for creating a moped from a Druzhba chainsaw with your own hands.
As mentioned above, the author already had experience in making a moped with a chainsaw engine, but the design was not so successful, and the maximum speed was about 35 km/h, the appearance also left much to be desired. The author affectionately calls his brainchild “Stool”))
I wanted to create something more interesting and practical, and in appearance it would look like a real moped or chopper, so that it would not be a shame to ride on such a vehicle on the street, but on the contrary, to catch the smiles and admiring glances of passers-by) This one was taken as an example and basis "bobber"
After that, a sketch was drawn up on a piece of paper with a regular ballpoint pen, and everything that needed to be radically changed and added was drawn.
What remained of the old frame was the lower part welded from professional pipe; bicycle wheels and rear and front forks were added to the new design. During the first day of work, the author welded the frame, installed the tank, headlight, and wheels.
All the parts were naturally old and even rare, the welds also needed to be cleaned, and then the prepared surface was painted in several layers with periodic drying with spray paint, the master used Montana paint.
Also, after painting, when the frame had dried, another layer of matte varnish was applied, also from a spray can.
The bicycle wheels were also old; it was also decided to paint them; first, the rim was sealed with masking tape and the wheel spokes were painted.
The wheels were also painted and hung on a rope to dry faster.
I assembled all the painted parts into a single structure and this is what happened.
But after working for several days, the engine unfortunately died, because it was also very ancient and probably its natural time had come to go for spare parts and remelting.
The engine was good, but I had to part with it.
In its place, I installed a new engine from the same Druzhba chainsaw, only newer from 1992, it had been stored away since the winter and now its finest hour has come)
As they say, “Oh, trouble, trouble, disappointment.” What to do? First of all, the author changed the gear ratio on the chain gearbox, consisting of bicycle sprockets and a chain.
It didn't help much, so that's not the reason. And then the idea came to water-cool the chainsaw engine. But how can this be implemented? In general, the author does the following, namely, he takes a plastic bottle and connects 2 hoses to it, one in the upper part for air intake, and the second in the lower part for supplying water through a dropper to the cylinder head of the Druzhba chainsaw engine. This kind of drip irrigation)) But according to the author, the engine has stopped heating up at high speeds and feels great.
Why did the author come up with such a wonderful moped with a chainsaw engine and water cooling?
The master also took and shared beautiful photographs of his brainchild, let's take a look)
As you can see, you can easily assemble a cool moped from old spare parts yourself, and you can also solve the problem of overheating by installing a water dropper. If you have spare parts from rare
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. 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
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.
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
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.
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
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.
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
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.
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 an additional star on the left side of the wheel and mounting the engine with the 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 to convert 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. A new sprocket and belt pulley are mounted on the carriage axle;
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 on the right side came from horse riding, since the sword, located at the rider's left hip, made it difficult to sit on the right.
If you have a craving for experimentation and would not refuse the opportunity to turn your bicycle into a homemade moped that can accelerate to 50 km per hour and above, this instruction is for you.
Using simple spare parts, you can build a bicycle with a chainsaw motor with your own hands. Let's get started!
- Carefully inspect and. The proposed modernization will significantly increase the load on all its parts. Therefore, every part must be inspected and well lubricated. Also check all fasteners and re-tighten the bolts. In addition to constructive necessity, all these actions are the key to your safety.
- You can make a bicycle with a chainsaw engine or a trimmer engine (also called a gas trimmer). If you are wondering how to adapt a motor from a lawn mower to a bicycle, then there is nothing complicated here. A gas mower is suitable for this design in the same way as a chainsaw. If you choose a chainsaw, make sure that its power is at least 2 kW. And if you have a trimmer, then 1 kW of power will be enough, since the lawnmower engine has a lower speed. The point is that you need to get enough traction to get moving. But at the same time, a more powerful engine means more weight. You need the motor weight to not exceed 6 kg, otherwise the bike will sway noticeably on the road.
- Check the engine for functionality. A bicycle with a chainsaw engine will, of course, roar loudly - we believe you are ready for this. Most likely, your neighbors and random passers-by will not be ready. Therefore, we recommend that you conduct your tests far from human habitation - in a forest, in a park, on a country road.
Pay special attention to checking the condition of the gas tank. Gasoline must not splash out, as this creates a fire hazard. The engine will be behind you, so you should pay special attention to this point.
- Now let's find out how to install a chainsaw engine on a bicycle. It is necessary to make room behind the cyclist, above. To do this you will have to remove the wing. The easiest way to use this scheme is to install a drive shaft, and use a tire instead of the driven shaft. This type of drive is the simplest and most effective; the design does not require the use of a large number of parts. The friction shaft will transmit rotation from the engine; for this, the shaft diameter should be approximately 25 mm.
- To install the engine on your bicycle, weld a metal stand to the frame located under the seat. you need it as low as possible, then your vehicle will be more stable in motion. You can secure the motor to the stand in any way - bolts, clamps or welding.
- The throttle cable and wires that will allow you to forcibly turn off the engine must be carefully secured to the frame. This is a matter of comfortable riding and cyclist safety.
- Ready! You can try out your new bike with a chainsaw motor. Keep an eye on it, it should be at least 3 atm.
Are there ready-made solutions?
Yes, everything can be much simpler if you purchase a ready-made set of parts to make a bicycle with a chainsaw engine. In addition to the engine itself, ready-made kits contain all the necessary fasteners, as well as a throttle cable, a power control handle, a forced engine shutdown button and other useful parts.
Conclusion
The dream of all the boys who puzzle over how to install a chainsaw engine on a bicycle can come true in adulthood. Now you have the opportunity to show your engineering ingenuity and assemble the exotic design described above by attaching a chainsaw motor to your bicycle with your own hands. In addition, this is a useful device: such a vehicle can be used for destinations without much stress - fishing, to the dacha, to the store, and most importantly, fuel consumption will be minimal. And even if you run out of gas, you can reach the end point of your journey in the traditional way - using pedals.
