Do-it-yourself scooter with a motor from a trimmer?

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

Based on the characteristics of this type of transport, it will have the following technical characteristics:

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.

Next you need to choose the appropriate wheels. They should be small in diameter, but wide enough and stable. Wheels from a garden cart or a go-kart car are ideal.

A chain drive will transmit power from the engine to the rear wheel. To do this, you need to make a gearbox. This is the most difficult stage of construction. The bicycle gear must be secured to the coupling of the lawn mower motor. First, 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 coupling and sprocket is by shrink fit or welding. Next, you need to connect the second bicycle sprocket with the adapter hub, which in turn must be seated on the shaft, and the shaft on bearings.

The second sprocket and brake pad are secured using another hub on a fixed shaft. Brake and gas levers and cables can be reinstalled from a moped or purchased at a car store.

Control

The scooter controls consist of a power switch, gas and brake handles. It is better to make gas in the form of a hook, because it is safer. In case of an unforeseen situation, such a handle is instinctively released.

The brake handle must be equipped with a switch that will turn off the engine when pressed.

Now let's look at a few instructions on how to make an electric scooter using different engines.

Homemade snow blower

There are many options for creating snow removal equipment based on a trimmer. The simplest method of modernization is to replace the knife with a rotor. This snow blower works like a shovel, but it is simply moved through the snow: the device scoops it up and moves it to the side.

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

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

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

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

The deflector is made like this:

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

The rotor is manufactured in the following sequence:

• cut rectangular strips measuring 25 by 10 cm from the metal sheet;
• cut and grind the plates to the shape of the blades;
• Weld them crosswise to the disk from the brush cutter.

A spatula is made from the remaining material. To do this, use a piece of tin 30 by 40 cm. The edges are folded along the long sides to form a two-centimeter side.

A self-made snow blower should be used at full throttle - this will extend the life of the device, because frequent pressing of the gas leads to engine damage. It is difficult to join thin metal by welding, because it easily burns through it. Therefore, the work must be performed by an experienced welder.

Do-it-yourself motor scooter from a chainsaw

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.

Motorized scooter made from a lawn mower

If you like to make something in the garage, or make a unique type of transport, this instruction is just for you. Here you will learn how you can equip your scooter with a gasoline engine. The author decided to use an unnecessary motor from a trimmer as a power unit. Similarly, you can install an engine from a chainsaw, lawn mower, and so on.

Materials and tools for homemade work: - an old scooter (can be made from scratch); — engine from a lawn mower; — bicycle wheels (will be used for spare parts); - bicycle chain; — metal pipes (found in an unnecessary chair); — cable for throttle control; — welding; - Bulgarian; - paint - wrenches, screwdrivers and more.

The process of making a gas scooter:

Step one. Freewheel device

A special feature of this homemade product is that the rear wheel is connected to the engine through a bicycle hub. This means that having gained a certain speed and releasing the gas, you can roll by inertia. But this is very convenient, because it allows you to significantly save fuel and also prevent engine overheating.

In other similar options, the torque is transmitted directly to the tire, which is not very professional.

As for installing the carriage, you will have to tinker. You may need to make some spacers, bushings, etc. to connect everything together.

Step two. Installing the sprocket on the engine

Petrol mowers come in different varieties; the author needed one that was equipped with a centrifugal clutch. Otherwise, if it is not there, it will be very difficult to use the scooter, because when you start the engine it will immediately drive away. And so the engine will idle without problems, and will only begin to move when the crankshaft speed increases.

Step three. Frame diagram

The author first made the frame wooden in order to decide on the creation of a metal one. The problem was that the new rear wheel mounts did not fit the old frame.

As a result, it was necessary to make a different rear fork. It must hold not only the wheel, but also the engine. A chair came to the rescue as materials, in other words, steel pipes are needed. Well, then the pipes are cut exactly according to the diagram and welded thoroughly. It is necessary to make a mount under the engine; for such purposes you will need a piece of strong steel plate. You need to cut a hole in the center for the clutch, and also drill four mounting holes for mounting the motor. Well, this sheet is welded to the rear fork.

Step four. Assembly

Now everything can be put together.

Step five. Painting

At this stage, the author paints the frame. If the original board has become bad or is not there at all, then it can be made from a sheet of plywood and then painted. The size is selected depending on your needs.

Step six. Connecting the engine

After painting, the engine is installed in place and everything is finally assembled. It is important to tighten the chain, otherwise it will fly off. Before driving, you need to spin the rear wheel and make sure that all the sprockets are centered and directly opposite each other.

To control the engine, you will need to connect the ignition button, as well as the throttle control cable. However, the button may not be located on the steering wheel, but the throttle handle will definitely be needed. You can use a cable from a bicycle brake or from a gear shift as a cable. As for the handle, the throttle handle can be made from the gear shift handle, throwing out unnecessary parts from it, as a result the handle will rotate freely. Well, or, as a last resort, you can control the throttle using the bicycle brake handle, but this is not very convenient, since you can get everything mixed up when riding.

To further strengthen the clutch axis, a steel axle and bearing were found, and an additional bracket was welded to the frame. Now the axle already has two supports, which has significantly reduced the load on the clutch. The axle is connected using a nut, since the engine axle has a thread.

Preparing to assemble a scooter from a lawn mower

In its basic design, a scooter with a power unit from a household trimmer is very similar to a motorbike. The difference between them lies in the weight and dimensions of the homemade product - a motor scooter is much lighter and more compact than a moped, so for its manufacture the designer can use engines with a power of up to 3-4 liters. With.

In addition to the power unit from the trimmer, to assemble the scooter the manufacturer will need:

All assembled elements, especially the frame used by the scooter, will need to be checked for rust and defects. There should be no signs of corrosion on them, otherwise the homemade trimmer will quickly become unusable.

What is needed to make a motorbike?

A homemade bicycle from a trimmer must be assembled from a certain list of parts and mechanisms.

To construct a motorbike from a lawn mower with your own hands, the manufacturer will need:

Along with the motor from the brush cutter, the manufacturer will need the entire fuel system along with the carburetor, factory clutch, ignition and gas tank. All internal mechanisms must be carefully prepared for assembling the bicycle - their faulty components must be washed and replaced.

How to make a motor scooter from a trimmer?

To design a scooter with a brushcutter engine, the manufacturer will need a strong welded frame. You can take it from an old scooter, or you can make a frame from metal pipes. Their individual pieces need to be welded to each other with a thick continuous seam. For additional reliability, steel spacers and ties must be welded to the main parts of the frame. The joints must be treated with an anti-corrosion agent. The finished support frame will need to be coated with a thick layer of primer and painted.

The further order of work should be as follows;

After assembling the scooter, the operator must test it. To do this, you need to take the homemade product out onto a flat surface and check it for maneuverability and smoothness. It is important to detect in time any extraneous sounds that may come from the wheels or engine. If they are not there, then the homemade scooter from the trimmer is ready for further use.

How to make a bicycle with a gas mower engine?

The correct assembly sequence plays an important role when constructing a moped from a trimmer. In addition, the manufacturer needs to prepare the workplace in advance and lay out all the elements used on it. This will save time during the subsequent production of homemade products.

To assemble a motorbike from a trimmer, you need to proceed in this order:

1. First of all, it is necessary to equip the driving rear wheel of the bicycle with a sprocket. To do this, you will need to install 2 elastic rubber pads on the rear wheel: the first of them should be located between the wheel spokes, and the second - directly behind them. The star itself must be tightly installed on the bushing, which is located on the outside of the wheel. In this case, the crescent-shaped part must be secured from the inside;
2. Next, you need to install the power unit from the disassembled trimmer onto the bicycle frame. It is best to choose the rear part of the frame for mounting the motor, behind the standard seat - usually the “trunk” of the bicycle is located in this place. It needs to be removed and a strong steel plate welded in its place. It is necessary to install a piece of rubber between it and the engine, which will partially dampen engine vibrations. The operator must use a clamp to secure the motor to the plate. It will prevent the driver from getting burned while operating a homemade moped;
3. After this, the power unit from the trimmer mounted on the bicycle frame and the sprocket will need to be connected by a drive belt or chain. To be able to regularly adjust the chain position, the operator must install a tension roller;
4. Then the bicycle with the engine from the trimmer must be equipped with a gas lever mounted on the homemade handlebar. The accelerator must be connected to the engine using a cable;
5. Next you need to install the gasoline tank. To install it, you will need to use a small metal or plastic platform located above the engine - this will ensure that fuel naturally enters the cylinder of the power unit;
6. In the end, the operator will only have to install the carburetor from the trimmer on the bicycle engine.

Before direct use, homemade bicycles with a trimmer motor must be carefully checked and tested. To do this, you need to carefully examine the structure of the unit and make sure that all the components necessary for its operation are installed on the frame. Then you will need to check the moped in action. After driving a few kilometers at low speed and making sure that the bike is in good condition, you can move on to more active use on the road.
