A considerable number of offers on the ATV market for young drivers today allows you to choose a modification with different characteristics and for any wallet. If you are not ready to spend a significant amount on purchasing an ATV, you have a creative streak, minimal technical knowledge and some special skills, you can make an ATV for your child with your own hands. Of course, you will also need some tools.
You can find many interesting ideas for an ATV on the Internet, perhaps you have your own ideas. Implementing them will certainly bring you great creative joy and will allow you to get an original ATV at minimal financial cost.
We assemble a children's electric ATV with our own hands
A battery-powered ATV for a child will, without a doubt, be a great gift that is environmentally friendly, easy to operate and does not require constant maintenance.
If you want to please your child with such a gift, you have two options. The first is to buy a ready-made ATV. The second option is more complex, but will bring a lot of pleasure to those who are “friendly” with technology. As you probably understand, we mean self-assembly of a children's ATV. We will talk about how to make an ATV for a child with your own hands in this material. If you are a creative person, then you will probably have your own ideas for creating an original model of a children's ATV. If this is a problem, you can borrow non-standard ideas from the Internet. The main thing is that you will enjoy the process and save on buying an expensive toy, because a DIY electric ATV will cost you much less than a ready-made one.
Wheels
It’s better not to skimp on wheels and buy new ones right away - go-kart wheels or a set of wheels for a large garden wheelbarrow will do. For an older child, it is better to take wheels with a wide tread - they are perfect for off-road use. Don't spare money on stamped discs - at least on the simplest ones.
An excellent solution for a children's ATV is rear wheel drive from an electric motor through a ready-made or homemade gearbox. Consider also the steering system - this will allow the child to easily handle the ATV and increase its safety.
Project
Start by calculating the concept, which should be based on the components that you have or that you could afford to buy: engine, gearbox, drive axle, suspensions, transmission shafts, wheels. A good option is to find one or another successful homemade ATV on the Internet and recreate its design on your own. It will be useful to first consult with its designer, who has experience not only in construction, but also in operation.
You must clearly understand in advance both the general layout and the connection points of each unit, without postponing the solution of any design issues until later. Otherwise you will have to redo something several times.
Engine
Important parameters for a homemade ATV: traction characteristics of the motor and its weight, type of cooling, methods of connection to the transmission. Calculate what the power of the power unit should be, and it depends on future operating conditions: load size, road conditions, intensity of operation.
The “two-stroke” from IZH or Jawa is the smallest engine that can be installed on an ATV for adults. “Toys” for children are a different matter.
An air-cooled motorcycle engine is the most affordable option, but it will often require forced airflow from a fan. If you are building a weekend fan transport, a two-stroke motorcycle with about 20 - 30 hp is enough. If you need a transporter for regular business trips, it is better to take a more durable four-stroke boxer from MT Dnepr or some kind of “foreign” unit. There are also known designs based on small car engines with a volume of 0.6 - 0.8 liters, and with efficient liquid cooling.
It can be made on the basis of a motorcycle one, or you can weld a completely new one. There are several difficult points: choosing the right diameter and thickness of the pipe, welding the parts securely and not making a mistake with the location of all the elements in terms of strength.
The frame for a small ATV is often converted from a motorcycle frame.
We strongly advise you to invite a certified engineer with experience in mechanical assembly production or in the field of equipment repair for consultation. Show him the draft design of the frame and explain where everything will be attached, ask what you might get wrong yourself: what diameter the pipes should be and how they are connected.
DIY electric quad bike: engine and battery
The battery and engine for a homemade ATV are selected based on the capabilities and needs of the driver. So, you can use a couple of engines from a Volga or a screwdriver, take an electric motor from a donor vehicle (for example, an electric scooter), or use your own idea. The main thing is that the electric motor provides sufficient speed for the child - 5-8 km/h is enough for the smallest ones, older children will need a higher speed, which means a more powerful motor.
As for the battery, it is important to install it in such a way that there is no need to disassemble the entire structure to recharge. A battery from a donor scooter, uninterruptible power supply, or another one you can find will do.
When all the main components are assembled, it’s time to deal with the appearance of the ATV - after all, aesthetics are extremely important for the baby. Ideally, you can use body kit elements from an old non-working model of a children's ATV, but your imagination can give you other original ideas.
Working on assembling an ATV will not only allow you to get a unique vehicle for little money. It will bring pleasure not only to adults, but also to children, since making a children's ATV with your own hands is a fascinating activity, very interesting and useful for every man.
Optional equipment
ATVs are used not only for pleasure trips, but also as a reliable, hardy assistant in the farmstead. They are used for transporting goods, crops, or used instead of a small tractor in the garden. And for these needs it is necessary to somehow place a lot of things on the ATV. If you need an ATV mainly for personal needs or going on a picnic, you can make a case for the ATV with your own hands, in which you can place the necessary things. But for a subsidiary farm, it is better to make a trailer for an ATV with your own hands. If you have already mastered assembling an ATV, then it will take you very little time to build a small trailer, but it will bring a lot of benefits.
An ATV is an excellent off-road solution. It is popular among fans of extreme recreation, fishermen, hunters and anyone who needs to get into places where a car cannot pass. This type of transport is easy to operate, has excellent maneuverability and is quite stable while driving.
Factory-made ATVs are quite expensive, so craftsmen choose the economical option: they make such machines themselves. Of course, this solution is not for everyone: you must not only have golden hands and the tools necessary for the job, but also have a good understanding of the structure of a car, motorcycle and the ATV itself.
If you have a persistent desire to make this miracle of technology yourself, you should start with planning. It is necessary to decide on the models on the basis of which the transport will be assembled, and draw up drawings for them. Be sure to think about what tools will be needed during the work process and make sure that they are in good condition. No matter how boring this activity may seem, nothing will come of it without prior preparation. If for some reason it is not possible to make a drawing yourself, you should find a ready-made version.
Next you will need the sources. From a technical point of view, an ATV is a cross between a car and a motorcycle. Accordingly, to make it you will need a motorcycle and a car. It is optimal to select domestic models on the secondary market; it will be inexpensive, but the quality is quite satisfactory for the construction of an ATV. It is better to use a small car like an Oka or Niva. Among motorcycles, the Ural is very popular for such purposes; you can take the IZH.

4x4 with car engine
A typical representative of the relatively small clan of ATVs with a car engine. The designer chose the most affordable and probably the most convenient option - a 33-horsepower two-cylinder engine from the Oka compact car. Its advantages over the Dnepr and Ural engines of similar power are greater durability and lower thermal load due to the presence of a liquid cooling system with a radiator.
The automobile engine takes the ATV to a new level of capabilities: long-term movement in difficult conditions and with a large load becomes possible.
This, as well as the features of the Oka’s front-wheel drive transmission, made it possible to make the ATV all-wheel drive. The automobile power unit was placed along the frame, respectively, each wheel drive of the car on the “quad” became a transmission shaft (cardan), transmitting torque to the front and rear axles. The drive axles are made on the basis of the Zhiguli axles, but each axle shaft was replaced with a drive shaft from Lada Samara.
Transmission diagram of a 4x4 ATV: 1 — Oka engine 0.75 l; 2 – clutch; 3 – manual gearbox with a “lowered” main gear; 4 – transmission shaft (CV joints VAZ-2108) to the front axle; 5 – gearboxes of driving axles (VAZ-2101); 6 – transmission shaft. 7 – wheels.
It's a little strange that none of the three differentials have locking. But to increase the torque in the Oki manual transmission, the gears of the main pair were replaced with a chain drive with a higher value. It is interesting that, according to the author himself, work on the project took 11 months; the amateur designer spent several hours every day in the garage - after the main work.
Selecting a donor for a new frame
How to make an ATV even easier to manufacture? You can simply use a donor frame, for example from a Ural motorcycle, by welding the rear axle to the standard swingarm and only slightly change the front suspension! The thick frame of the Urals is made of good steel and has an excellent margin of safety. And an engine with high torque is perfect for this purpose. As for the gearbox, it is better to use it from the Dnepr motorcycle. It is designed for good loads, is distinguished by precise gear shifting, and the most important thing is the presence of reverse speed, which is a mandatory function of a full-fledged ATV. Photo example of a homemade ATV from the Urals below:

An ATV is an all-wheel drive vehicle and a motorcycle, an endurocross bike, in one package. The features of this type of transport are compactness, tires with deep treads for better off-road traction, 1-2 seats and no roof over your head. This type of transport first appeared in Japan in the 1970s and won the hearts of many off-road romantics. Such transport will be of interest to hunters, fishermen, and those who like to conquer impassable terrain. Many of us dream of such a toy for adults. We will tell you how you can make your dreams come true with your own hands.

Choosing an ATV engine
The most important part for your all-terrain vehicle will be the power unit. Motorcycle engines are most often used (they are economical and small in size). Let's say, an engine from Ural or Minsk, IZH Planet or IZH Jupiter will do. You can adapt an engine from a VAZ or Oka to your ATV. To avoid engine overheating in hot weather, you need to choose a model with an air cooling system. The most popular option is to transfer automotive forced cooling.
Modernization of an existing frame or drawings from scratch
The easiest way is to take a finished motorcycle frame as a basis and weld all the missing parts onto it. The order of your actions is as follows: disassemble the old motorcycle. We leave only the frame. We cut off the rear part of the frame with the pendulum fork mount. We extend the frame with pipes and weld the bridge (use jibs and gussets). First turn the car axle over so that the quad can go forward and not backward (because on the Ural gearbox the direction of rotation is reversed at the output).
Remember that in case of replacement, the axle gearbox must be easily removed. We are looking for spare parts for a car: 2 front hubs, a rear axle (so that the discs match the fasteners with the hubs), a driveshaft, front suspension arms, tie rods, a ¾-inch round water pipe.
If there is no donor motorcycle, then the frame is best made from durable alloys: pipes, profiles, spot welded together.
For the load-bearing parts of the frame, you can buy water pipes (VGP 25×3.2). You must have equipment that will allow you to bend the pipes in the right place.
For the body, we prepare a frame from a 70×40 pipe. The length should be no shorter than the spring, and the width should correspond to the size of the bridge. When using jibs, do not forget about the torsional rigidity of the structure.
We connect the cardan to the box using a “Ural” rubber coupling. Through the hinge crosspiece we connect the cardan to the bridge with a flange. If the donor was IL, then the drive is carried out by the original chain.
Increased functionality
Now that the frame and chassis of the ATV are assembled and the engine is installed, you need to think about secondary structures that will make it practical to use the equipment. The fuel tank is well suited for a Ural motorcycle. Its impressive capacity will be enough even for a car engine. An important modification would be the installation of a snorkel. Since the engine is located quite low in the frame, the air filter accordingly takes in air from below. To prevent water from getting into it when fording, it is highly recommended to do this. The exhaust system also needs to be completely redone, with exhaust gases being removed at a fairly high level so that water does not get inside. Also, for an ATV you need a large, wide seat; by moving your body weight, you will be able to achieve better control when moving. An underbody skid plate can be made from aluminum sheet metal to protect the front suspension arms and engine. A winch installed in the front part would be useful in the forest. You can use car fog lights to illuminate the road.
Components of a homemade electric ATV
Typically, a frame for a homemade ATV is created from scratch from existing material, such as parts from an old motorcycle. To create a spatial welded frame, light and flexible pipes with good strength properties are suitable. The main elements can be made from pipes Ø25 mm with a wall thickness of 3.2 mm, and crossbars, struts and other auxiliary parts can be made from pipes with a diameter of 20 mm.
Thick pipes or a massive profile should not be used - they will add excessive weight to the structure, which will negatively affect speed and maneuverability. When assembling a children's electric ATV with your own hands, it is appropriate to use a frame made of durable, hard polyethylene. The rear part, where the transmission parts and motor are attached, is recommended to be made of light and durable aluminum alloys.
Suspension
Motorcycle shock absorbers with springs are suitable for suspension. The suspension is made A-shaped and movably fixed on the frame. Shock absorbers and springs must be strong so that they can confidently support the weight of the assembled structure. They should also provide a smooth ride and good control when driving over potholes, potholes and other uneven surfaces. You can make independent wheel suspensions on 2 triangular wishbones using shock absorbers from Oka or another car. Levers can be welded from round pipes Ø20 mm.
Preparatory stage
So let's get started. First of all, prepare your tools and equipment. A lot of welding work will be required, for which manual electric arc welding is quite suitable. Choose electrodes for welding critical and vibration-loaded structures, which will be the ATV frame. By the way, this very frame can be welded with your own hands from ordinary water pipes. These are easy to find at your nearest scrap metal shop or metal depot. Choose a pipe diameter from 25 to 32mm, and the wall thickness should be around 3mm. To bend such pipes, it is advisable to have a pipe bender, but if you don’t have one, then you can bend the pipes for the frame frame manually using a lever, heating the place of the desired bend with a gas burner, or better yet, with an oxygen-gas torch.
Homemade ATV from a Ural motorcycle
If you are the owner of an old motorcycle and it is gathering dust in the garage, then do not rush to dispose of it. The Ural model is excellent for processing into an ATV. Assembly of the all-terrain vehicle will consist of the following stages:
What rights are needed to drive an ATV can be read here .
- frame modification; installation of the instrument frame; engine installation; suspension installation.
What is needed for work:
- bridge; shock absorbers; welding machine; Bulgarian; brake system; Tie Rod; metal profile sheet; motorbike.
Before you start assembling, you should decide on the type of control of your homemade ATV. It can be motorcycle and steering. The next step is to modernize the frame; for this, the vertical seatpost tubes must be moved back 40 mm. Next, we weld the bridge to the Ural swingarm, slightly trim the lower fork and seatposts. Next to the bushings of the pendulum suspension, we weld struts made from pipes. We shorten the bridge to make the vehicle compact and more maneuverable. Now we are making a driveshaft, which can be constructed from Oka axle shafts. We need square pipes 25*25*2 mm for the manufacture of the front suspension. You can borrow steering knuckles from a Zhiguli car. Close attention must be paid to the braking system. It is better to purchase it separately to ensure maximum safety. When all the main elements are assembled, you can begin installing headlights, turn signals and brake lights. We cover the ATV with a profile and prepare it for painting.
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.
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.
As an additional comfort for the driver, you can install fenders, since clods of dirt and water can get on the engine. The resulting unit is capable of speeds of up to 60 km/h.
Below is an approximate drawing that can be used to convert a bicycle into a moped.
Do-it-yourself ATV - a full-fledged equipment or just a hobby?
Assembling an ATV with your own hands is fun. The creator gains experience, trains resourcefulness and patience. However, homemade all-terrain vehicles should not be considered as a full-fledged alternative to factory models - even the best ATV, assembled with your own hands, will obviously be worse than a serial one. In addition, self-assembly takes a long time - even experienced mechanics spend a year or more.
If you need high-quality equipment, take a closer look at CFMOTO products. If you don’t have the money to buy it here and now, you can take out an all-terrain vehicle on credit and gradually pay off the funds without putting a strain on the budget. New equipment is covered by a factory warranty. In terms of comfort and reliability, serial CFMOTO models are unrivaled - you can go on a trip with them or go for high-speed rides.
