Do-it-yourself engine from a lawn mower to a bicycle. How to make a motorbike from a trimmer

Like many, I started my journey with the legendary “deshnik”, which I put on the teenage bike “Tisa”. The device turned out to be funny, but it was accompanied by a gasoline stink in the apartment, dirty hands and a shaman's tambourine to exorcise evil spirits from the carburetor and ignition. The device did not perform utilitarian functions in any way.

But one day I was lucky enough to ride a mountain bike with a motor from a trimmer (lawn mower) and a belt drive. Although it was winter and I did not ride for long, I experienced a culture shock! In frost, the engine started up perfectly both cold and warm, pulled perfectly, was perfectly clean and did not stink at all. And the "maximum speed" of 55 km / h with such traction "deshnik" never dreamed of!

In general, a belt kit was soon purchased with a two-stroke motor from a 1.5 hp trimmer. plus Mountain bike stronger. Fortunately, there was no limit, but only until the first rain ... It turned out that the drive belt loses strength and breaks when wet, changing it on the road is not very convenient, besides, the cost of a new one bites. Rain in Moscow is not uncommon. But I was already used to riding such a comfortable motorbike and didn’t want to give up the idea, I decided - the chain and only the chain would save the “father of Russian democracy”!

Required gear ratio forced to use a driven star almost the size of a bicycle wheel, but, fortunately, there was a gearbox from a Chinese minibike that fit perfectly on the trim motor and made it possible to use sprockets of the usual sizes. Drive components - public bicycle: single speed wide chain, chainring from HVZ bike for 51 teeth and a “free wheel” (freewheel with an asterisk) from BMX, as well as a bicycle brake handle as a gas trigger.

In addition to purchased parts, there are many original components in the design. These are steel racks that are attached to the bicycle frame, a motor mount (holds the gearbox with a motor), a chain tensioner with caprolon rollers, a driven star mount on the wheel, an adapter from the gearbox shaft to the freewheel. He designed the details himself, and made them at a nearby defense plant.

Of course, it was not possible to assemble the ideal design the first time, I treated children's sores for another year. I selected the optimal materials and design solutions, tried different layouts, and rode, rode, rode ...

What happened in the end? Ultralight (curb weight - 25 kg) motorized transport with maximum speed 55 km / h, dynamics at the level of simple Chinese scooters, fuel consumption of 2 liters per 100 km (power reserve on one tank 50 km), which does not stain oil at all and does not smell of gasoline. The absence of smell and dirt helps me save money on a garage or parking lot, the motorbike is in the apartment and does not bring discomfort to the family at all. Particularly pleased that all the "pedal" functions are fully preserved. It remains to shift gears and easy pedal travel (thanks to the “freewheel”), with a lack of traction, the motor can always be helped by pedals and drive up any hill. The running of a modern mountain bike is very strong and reliable, disc brakes provide very confident braking, and large wheels make it easier to overcome our “directions”.

After completing the design improvements, I have already traveled more than 4000 km and during this time I have only changed the drive chain once, the spark plug twice, and once I cleaned the fuel system - a good indicator of reliability and unpretentiousness.

For lightness and daring agility, I called my motorbike "Hare". Now I drive the "Hare" every day to work, and in traffic jams it has no equal. It's so narrow and agile that during rush hour I get home faster than before on a motorcycle, and the fare is ridiculous. There were also small trips, trips out of town, even from Moscow to Yaroslavl. But a motorbike, of course, is not for the track - it’s not comfortable to “beat” on it, but in the city and country trips I can’t imagine the best transport for myself!

A person is always trying to make his life easier and construct something new from improvised means. Something that will help him spend less effort and energy on daily activities. Such inventions can safely be attributed to a home-made motorbike and motorized scooter. If you have at hand a motor from a lawn mower and spare parts (or a whole) bicycle / scooter - why not give them new life? We will tell you about how to assemble a scooter and a bike with a trimmer motor in this article.

How to make a motorbike from a trimmer with your own hands?

Making a motorbike with your own hands from a lawn mower is not as difficult as it might seem at first glance. First, determine how powerful the engine is on the trimmer. It must be at least 2 horsepower. Otherwise, the future unit will not be able to travel a long distance, or even not move at all.

The next step is the design of the drive. To do this, you will need to make a drive pulley (attached to the motor), a driven pulley and a special frame for the engine. The torque transmitting belt is recommended to be selected at the end of the assembly, based on the dimensions of the entire structure.

You can install the engine from a trimmer on a bicycle by making a special small frame from improvised metal scraps. The second point is the fastening of this structure to the bicycle. It must be reliable and at the same time convenient in terms of maintenance. This suspension must be securely fastened, resistant to vibration and, preferably, quickly and easily detach.

There are two mounting options:

bolting;
welding fastening.

Each method has its pros and cons. Consider all the features of your equipment and its operating conditions, and build on these data when choosing a mounting option.

Additionally, do not forget to attach details such as a small fuel tank, an exhaust pipe. Installing an additional brake will also not be superfluous, since a bike with a trimmer engine will be much faster and more powerful than a regular one.

We also suggest that you familiarize yourself with the video, which shows the process of constructing a motorbike from a trimmer:

Do-it-yourself scooter with a trimmer motor?

A homemade scooter with an engine from a trimmer is an excellent home transport for entertainment, traveling a short distance outside the carriageway (on sidewalks and park paths, for example).

Based on the characteristics of this type of transport, it will have such specifications:

will be able to develop a low speed (no more than 40 km / h);
the small diameter of the wheels will cause little stability, which is fraught with skidding of the scooter;
such equipment is not designed for heavy loads and heavy loads;
trusting children with such a “toy” without adult supervision is not worth it.

The assembly process itself is relatively simple. First, find an old scooter (if you don’t have one, you can weld a similar frame yourself). If you take an already assembled unnecessary scooter, it is appropriate to strengthen its frame with a 15 mm square metal profile.

transfer power from the motor to rear wheel there will be a chain drive. To do this, you need to make a gearbox. This is the most difficult stage of design. The bicycle gear must be fixed to the brushcutter motor clutch. Previously, the dimensions of the coupling should be adjusted to the gear (cut off the teeth from it, make it thinner by turning it on a lathe). The best way to fasten the clutch and sprocket is by shrink fitting or welding. Next, you need to connect the second bicycle sprocket to the adapter hub, which in turn must be planted on the shaft, and the shaft on the bearings.

The fastening of the second sprocket and the brake shoe is carried out using another hub on a fixed shaft. Brake and gas levers and cables can be reinstalled from a moped or bought at an auto shop.

The required gear ratio forced the use of a driven star almost the size of a bicycle wheel, but, fortunately, there was a gearbox from a Chinese minibike that fit perfectly on the trim motor and made it possible to use sprockets of the usual sizes. The drive components are publicly available bicycle ones: a single-speed wide chain, a 51-tooth star from a KhVZ bicycle and a “freewheel” (overrunning clutch with an asterisk) from BMX, as well as a bicycle brake handle as a gas trigger.

What happened in the end? Ultralight (curb weight - 25 kg) motor vehicles with a maximum speed of 55 km / h, dynamics at the level of simple Chinese scooters, fuel consumption of 2 liters per 100 km (power reserve on one tank 50 km), which does not stain oil at all and does not smell of gasoline .

Assembling the cultivator

If there is a cottage or just a plot of land, then the cultivator will help facilitate soil cultivation. Traditionally, a chopper is used for these purposes, but working with it takes a lot of time and effort. Using a cultivator will reduce labor costs, and the whole process will take a shorter time period. Factory-made equipment is expensive, so with limited funds, the question arises of self-assembly of the cultivator. For this, both gasoline trimmers and electric scythes are suitable.

To create the simplest sample of technology, you should stock up on the following tools and materials:

grinder with a set of discs (suitable diameter - 125 mm) for metal;
drill with drills of various diameters;
welding machine;
electrodes;
electric jigsaw or hacksaw;
emery machine with two abrasive wheels of different grain sizes;
a functioning gasoline trimmer;
pitchfork;
a steel tube suitable in diameter for the brushcutter shaft;
hand tools: keys, hammer, pliers, core, tape measure and marker;
a sheet of metal with a thickness of 3 to 5 mm and dimensions of at least 10 * 10 cm.

Manufacturing process starts from the working part. For this purpose, curved rods of garden forks will serve. Their recommended length is from 10 to 15 cm - this is enough to loosen the soil.

The working nozzle is made in the following sequence:

the fork teeth are flattened to a width of 1 cm;
on emery, using a circle with a fine abrasive, sharpen cutters;
using a jigsaw, cut a circle with a diameter of 10 cm from the metal;
process it on an emery machine until an almost perfect shape is achieved;
at regular intervals, prepared cutters are welded to the metal circle (the recommended number is 3).

With more than 3 pieces, the number of cutters, the load on the equipment greatly increases.

On next step it is necessary to attach a cutter for weeding to the trimmer. The process is greatly simplified if reverse thread, located at the end of the scythe shaft, onto which the manufactured working part is simply wound. To do this, a tube with a nut is pre-welded to the cutter.

With locksmith experience and welder skills, converting a trimmer into a cultivator is quite simple. The financial costs are insignificant. If an electric scythe is used in the work, then you will need to think about an extension cord so that it reaches the entire treated area.

DIY lawn mower

The lawnmower facilitates the maintenance of decorative grass plantings, and also speeds up work in the presence of large areas that need to be processed. There are many ready-made, easy-to-use models on the market for such equipment, but they are expensive, so they are not available to everyone. They also quickly fail in the presence of large weeds and stones on the site. Homemade products are much cheaper than factory counterparts, and besides, they are more practical to use.

The components of the lawn mower design are:

engine (gasoline or electric), which is the basis of the created mechanism;
a frame designed to fix all the details of the device on it;
casing for protection;
knives;
handles and wheels;
block of the control system of the created unit.

Many craftsmen have invented various ways converting a trimmer into a lawn mower. The simplest version is shown in the video:

Very common in practice frame version homemade device. Tools and materials for the independent implementation of the project will require the same as in the previous case. Plus, you'll also need:

a sheet of plywood (or metal 3-4 mm thick);
metal corner 25x25 mm;
2 m pipes of different diameters.

The manufacturing process is as follows:

a rectangular frame 50x60 cm is welded from the corner;
wheels of the right size are installed in the corners, which can be taken even from old toys;
on top of the frame, plywood cut to its size is fixed or metal is welded;

in the center of the cart, a hole is made for the trimmer rod and fasteners for it;
make a knife or choose a suitable ready-made option;
then fix the lawn mower on the trolley;
install a knife;
mounted to protect against flying in different sides cut grass shroud at the back of the trolley;
start testing the device.

Important! The diameter of the wheels is selected so that the knives do not reach the soil by 5 centimeters.

There are many ways to make knives, and their shape (design) also varies dramatically. In this case, various materials and old tools are used (for example, an old saw for wood). The main principle is that the knives are well sharpened and balanced - this is necessary to prevent vibrations of the equipment during operation.

It is often found that they do not use an old lawn mower, but only the engine from the trimmer and its control unit. In this case, you will need to make handles for the trolley and fix all the details of the structure on the frame.

When assembling the lawn mower and while working with it, it is imperative to adhere to safety precautions to avoid injury. You can also attach a bag to the machine to collect the cut grass.

We make a motorbike

From an ordinary bicycle, home craftsmen managed to make a more practical vehicle - they moved the engine from a lawn mower to it. At the same time, options are practically implemented both with a gasoline engine and with an electric motor.

Required tools, materials and parts

Electrical engine the bike is powered by a battery, which, depending on the power of the unit (it is taken 0.35-1.2 kW), lasts from 30 minutes to 2 hours.

For alteration of the bicycle are used two- or four-stroke petrol engines. The latter option consumes less fuel and is not as noisy during operation. The recommended power is from 1.5 hp, and the best option is 2 hp. When using a motor with a smaller parameter, the motorbike will barely move or will not be able to move at all.

The rotational movement from a gasoline engine to a bicycle wheel is achieved by using belt or chain drive . Because of this, you will additionally need to do the following details:

a metal suspension in the form of a frame with sides to fix the motor on the bicycle frame;
driven and driving pulleys or sprockets for attachment to the engine and wheel, respectively.

Using a chain drive is more practical than a belt drive, because the belt wears out faster, especially if it gets wet regularly.

To implement the project, you need to choose suitable gearbox. After installing the pulleys, choose the belt of the desired size.

The dimensions of the frame for the engine depend on its dimensions. The suspension itself is fixed to the frame of the motorbike:

bolted connection;
by welding.

The last strength option is the best if the welder is good. If the design of the bicycle frame allows, then the suspension is replaced with a clamp, which fix the engine. This mounting option is more practical. The method of fixing the motor should be convenient, reliable and allow you to quickly remove it if necessary.

Doing all the work with your own hands with an old, functioning trimmer, a bicycle and a small set of tools will require time and patience from the performer.

Construction assembly sequence

In order to independently assemble a bicycle with a gasoline engine, you will need, in addition to the materials and parts considered, also:

controller;
cable for adjusting the operation of the motor;
fuse;
exhaust pipe welded by welding;
sleeve;
washers;
bolts;
chain tensioner.

The motorbike is assembled according to the following algorithm:

put on the back bicycle wheel asterisk;
fix the engine (with an asterisk on the shaft) with a clamp on the frame behind the seat or on the trunk, if it allows design features bicycle, otherwise you will need to choose another convenient place for this purpose;
put a chain on the sprockets of the wheel and motor;
attach the tensioner;
adjust the chain tension;
fix the throttle;
stretch a cable from it to the engine;
fix the fuel tank;
mount the carburetor.

For personal safety during the operation of a motorbike, the braking system is modernized, the wheel tires are changed to non-slip products, the integrity and stability in motion of the created structure are checked. After the entire structure is assembled, it is tested, having previously examined it for imperfections.

Homemade snow blower

There are many options for creating snowplows based on a trimmer. Most in a simple way modernization is considered to be the replacement of the knife with a rotor. Such a snow blower works like a shovel, but at the same time it is simply moved through the snow: the device rakes it and moves it to the side.

To carry out the planned alteration, you will need the following materials and tools:

mower with a straight bar, at the end of which a gearbox is installed;
a metal keg, even a beer keg is suitable, for example, from the Baltika drink;
cutter from a trimmer with many teeth (used for mowing dense thickets of grass);
drill with drills;
grinder and welding machine.

Instead of a barrel, you can use a thin sheet of metal (tin) 1.5 mm thick.

The assembly process of the snow blower is performed in the following sequence:

cut in a circle, stepping back from the bottom of 15 cm, a barrel;
make a hole in the bottom for the brush cutter gearbox and drill 3 more small holes to fix its shield;
a 10 by 10 cm square is cut out on the side to throw snow through it;
a third of the open front of the barrel is closed with a piece of metal (tin), while the ejection hole should be located along the center line of the damper;
make a rotor
make a deflector that will direct the ejected snow in the right direction;
weld it to the body at the location of the hole for the ejection of snow mass;
attach the blade from below;
install the brush cutter gearbox and fix it with bolts;
put the rotor like a simple work knife.

The deflector is done like this:

a strip is cut out of metal, the width of which is 15 cm and the length is 30 cm;
slightly bend the workpiece;
10 cm high sides are welded from long sides so that snow does not scatter at the exit.

The rotor is made in the following sequence:

cut from a metal sheet rectangular strips measuring 25 by 10 cm;
cut and grind the plates in the shape of the blades;
they are welded with a cross to the disc from the lawn mower.

A spatula is made from the remnants of the material. To do this, use a piece of tin 30 by 40 cm. Along the long sides, the edges are bent to form a two-centimeter rim.

A self-made snowplow should be used at full throttle - this will extend the life of the device, because frequent pressing on the gas leads to engine breakdown. Thin metal is difficult to connect by welding, because it easily burns through. Therefore, the work must be carried out by an experienced welder.

Ice drill from gas scythes

The benzokosu can be converted into an ice drill. Factory counterparts are quite complex and powerful devices. Structurally, the technique is a screw connected to the engine (in most cases two-stroke units are installed). Industrial machines are equipped automatic security systems, which turn off the ice drill in the event of a malfunction and exclude the possibility of accidental start. Models also differ in the number of speeds: one- or two-speed.

For lovers winter fishing it is unprofitable to buy a factory unit, and it is difficult to work with a manual device with a large thickness of ice. It will help to save effort and money by converting an old trimmer into an ice screw.

In addition to the lawn mower, you will need a drill (factory or home-made) and tools for assembling the final structure. The difficulty lies in attaching the working part to the trimmer. Here, much depends on the existing model of lawn mowers.

The following videos show how an ice screw made from a trimmer works:

The last video contains a possible option for attaching a drill to a brushcutter.

Compared to industrial counterparts, a homemade ice drill is low power device, but enough for drilling holes with a head. It also weighs little, which makes it easy to transport.

Other homemade options

Thanks to an economical and reliable engine, the trimmer is the basis for many other homemade products. Below we briefly describe the possible options and provide video instructions for their implementation.

Converting a trimmer to a chainsaw

A chainsaw can also be made from a gasoline lawn mower. To bring the rationalization idea to life, old models of devices will be needed. All details will be taken from them. The video below shows the result.

Converting a trimmer into a gasoline saw consists in installing this part from a lawn mower instead of its own engine.

Making a snowmobile for children

The trimmer can also be converted into a snowmobile. The process consists in installing the engine on a structure equipped with skis. Due to the insufficient power of the motors available on lawn mowers, the created independent equipment is capable of carrying only a relatively small weight. It also moves on relatively flat terrain. Such a homemade product will serve as an interesting and useful toy for children.

The movement of the snowmobile is carried out using a propeller or chain drive.

The videos below show some possible options for home-made equipment:

Home craftsmen have come up with many different ways to adapt a trimmer motor to a snowmobile. Here, the limitations are associated with personal imagination and the existing list of unnecessary devices and equipment that can be used to create homemade snowmobiles.

Motokosa can be converted into a motor auger, which will also be used as an ice auger if necessary. As a result, construction work will be accelerated and require less labor. With a motor drill, they make recesses for fence posts, a foundation of piles and for the erection of other structures.

Both electric and gasoline trimmers are remade for this purpose.

scooter

In addition to the bicycle, the engine of the lawn mower is also installed on the scooter. The assembly principle is similar to the creation of a motorbike, only the design features of the scooter are taken into account.

Having an old working and unnecessary trimmer at your disposal, you can make various technical devices with your own hands, not only those discussed above. Your own fantasy tells different variants. But when creating any device, you should remember that it would be safe for those around you and those using it.

How to design a bike with a trimmer motor?

Despite the fact that technological progress does not stand still, and every year we are pleased with new vehicles, today there are still lovers to do something unusual and original on their own. Who could imagine at the end of the twentieth century that in the twenty-first century regular bike will be supplemented with an engine from a lawn mower.

Before disassembling the trimmer and starting to design a bike with a motor from a lawn mower, it is worth Special attention turn to engine power. After all, it will depend on the power how long you can ride on a modernized bike. Ideally, the engine power should be at least 2 horsepower. In the event that you install a smaller engine, homemade bike may not even move.

How to make a drive?

On a bike with a brushcutter engine, torque is transmitted using a belt. For this, it is additionally necessary to make:

drive pulley, which is subsequently mounted on the engine;
driven pulley, the diameter of which must be less than the diameter of the wheel rim;
metal suspension for fixing the engine on a bicycle frame.

It will also be necessary to select the appropriate gearbox. The size of the belt that will drive the wheel is calculated after the pulleys are attached to the future motorbike.

How to install a trimmer motor on a bike?

Answering the question of how to make a motorbike out of a trimmer, first we will answer the question: “How to fix the engine on the frame?”. For reliable fixation, it is necessary to make an additional metal suspension, which will resemble a frame with sides.

The configuration and dimensions of such a frame must correspond to the shape of the engine used. At the next stage, it is worth thinking about the options for attaching the suspension to the bicycle frame, there may be two of them.

Fastening with bolted connection.
Fastening by means of electric welding.

Each option is good in its own way, but it is the second one that is considered more durable, because when bolted, the possibility of loosening the bolts from vibration cannot be ruled out. At the last stage, options for fixing the engine itself to a fixed suspension are considered. Don't lose sight of the fact that you will have to remove the engine for maintenance from time to time. Therefore, the fixation must be reliable and convenient at the same time for quick removal of the engine.

In conclusion, I would like to note that it is possible to make not only a bicycle, but also a scooter with a motor from a trimmer. To do this, you need to make small structural changes, but the assembly principle remains the same.

Safety is the foundation of your health!

Considering the fact that the vehicle is equipped with an engine, it is necessary to carefully consider safety issues, namely:

reliability brake system;
structural stability and integrity;
wheels must be "shod" in anti-slip tires.

By carefully considering these issues, you can not worry about your safety, and enjoy a walk on an improved bike.

In the great variety of shapes and designs in the world of velobikes, models equipped with motors are no longer considered a curiosity. Such bikes are quite expensive, many manufacturers are trying to reduce their cost by using cheap equipment, hi-ten frames, which does not make such a bike practical to use. There is a wide range of bicycle motors on the market, to which all the parts necessary for installation are also attached. Equipping your bike with such a motor will not be difficult, but if you want to save a lot of money, as an option, you can simply remove a suitable motor from an old moped, chainsaw or lawn mower and create it from a trimmer with your own hands.

Upgrading an ordinary bike in this way will not require enormous efforts, but you will have to be patient and tinker a little. First you need to decide on the type of engine that will be installed on the bike.

Types of engines

Gasoline (internal combustion engine) favorably differs from electric in its independence from the mains or battery. It happens 2- or 4-stroke. Both are suitable for installation on a bicycle, but a 4-stroke will make less noise and use less gasoline. The power of such engines is 1–3 horsepower; for tuning a motorbike, it is better to choose from 1.5 liters. with., because it makes no sense to supply it with a motor of less power.
Electric motor. Usually trimmers do not equip powerful electric motors. As a rule, their power is from 0.35 to 1.2 kW. This is quite enough for the engine removed from the lawn mower to fit on the bike. The electric motor can be powered by a battery or from the mains. can work without charging for 30-120 minutes, depending on the power and capacity of the engine, so if it is impossible to recharge, you will have to drive your bike in the classic way, pedaling.

We put the engine from the lawn mower on the bike

There are no differences in the design of the motor from the trimmer and the motor removed from the lawn mower, so it is installed in almost the same way. But paired with such a motor, it’s better than a belt, because, getting caught in the rain, the belt will wear out very quickly and become unusable.

Grass trimmer

So, to design a bike with a trimmer engine, we need:

a serviceable bike (it doesn’t matter if it’s new or experienced, as long as it’s working);
trimmer engine;
chain (you can, of course, use a belt for the same purpose, but this is very impractical and not for long);
tensioner;
sprocket (suitable for the selected engine, possibly homemade);
a clamp that attaches the motor to the bike (you can make it yourself from some metal plate or buy it without bothering);
small engine with throttle handle;
fuse;
controller;
exhaust pipe (if we put a gasoline engine, we weld the pipe by welding);
bushing, washers, screws.

We put an asterisk. We attach two rubber pads to the rear wheel, one between the spokes, the other behind them. We put the star on the sleeve located on outside wheels, and fasten the crescent from the inside.
We fix the engine with a clamp. Depending on the model of the bike, we choose a place for mounting the motor. Most often it is convenient to place it either behind the seat.
We stretch the chain on the sprocket and the engine and immediately install the tensioner to adjust the chain tension.
We attach the throttle handle and from it we draw a small cable to the motor.
We carry out fastening of the gas tank.
Installing the carburetor.

When a bike with a motor from a trimmer has already been made, you need to carefully check all the mechanisms for any imperfections, since not only the functionality of your bike, but also your own safety will depend on this.

motorbike it is an indispensable mode of transport, especially in the town. After all, finding a way out of limitless traffic jams with the help of such a technique will not be difficult. But this does not mean that in rural areas the device will not cope with the ride. On the contrary, it will become a real all-terrain vehicle, with the help of which it will be possible to be in a suitable place in a frisky time. Moreover, a license to drive it is not required, because it can be a real way out for those who failed to get them.

DIY motorbike

The Russian market offers buyers a motorbike with a type D engine. But such devices have some drawbacks, the most significant of which is the presence of only one gear, due to which the device's capabilities are significantly reduced. However, their price is not very high, because, as they say, you get what you pay for.

But you can do homemade units with their own hands. This requires all the necessary materials. Not so long ago, motorbikes were the sacred dream of any boy. Yes, in childhood, such homemade products caused a lot of admiration. The difference from the usual great was that such a device was supplied with an internal combustion engine. And the current in the circuit could be made using an ordinary trimmer for hair. Although the introduction of a trimmer is not inevitable, since it can be changed with any other suitable device.
