A battery-powered ATV for a child will undoubtedly be a great gift, while being environmentally friendly.
A battery-powered ATV for a child will undoubtedly be a great gift, at the same time safe for the environment, easy to operate and does not require constant maintenance. If you want to please your child with such a present, you have two options. The first is to buy a ready-made ATV. The second option is more difficult, but for those who are "friends" with technology, it will bring a lot of pleasure. As you probably understood, we mean self-assembly 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 "tension", 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 an electric ATV with your own hands will cost you much cheaper than the finished one.
How to make a children's ATV with your own hands?
Decide on the look and design of your brainchild. Basically, you can assemble a children's electric ATV of any size and any complexity - everything will depend on your abilities and technical skills. You can stretch the process for months, but if you want to quickly please the child, choose a simpler design, it can be modified when the child grows up.
As a basis for the future ATV, you can take a donor model - for example, an old ATV or child car, or make the frame yourself. If you chose the second option, an accurate drawing is required. When making it, take into account the possibility of upgrading the ATV in the future - the frame should turn out to be strong in the suspension. You can draw a drawing of the frame of a children's ATV with your own hands yourself or take an idea from the Internet. At self-made frame for an ATV pay special attention to the quality of the seams when welding. A square profile of 25x25 mm (or another size), as well as a ¾ inch pipe, are suitable as material for the frame.
Wheels
It's better not to save on wheels and buy new ones right away - go kart wheels or a set of wheels for a large garden wheelbarrow. For an older child, it is better to take wheels with a wide tread - they are perfect for off-roading. Spend some money on stamped discs - at least on the simplest ones.
An excellent solution for a children's ATV - the drive on rear wheels from an electric motor through a ready-made or homemade reducer... Think about the steering system - this will allow your child to easily cope with the ATV and increase its safety.
Engine and battery
These components are selected taking into account the capabilities and wishes of the young rider. There is no limit to imagination - from the screwdriver motor to infinity. It is important that the installed electric motor makes it possible to develop the desired speed - for kids, 5-8 km / h is enough, for older children it is interesting, of course, the speed will be needed more. When choosing a battery, consider its capabilities. It should be installed in such a way that you do not need to disassemble the ATV for recharging. You can use a battery from a donor scooter, uninterruptible power supply, or another suitable one.
When all the components are installed, take care of the aesthetic component - after all, for the child, first of all, it is important appearance his transport. You can use the elements of the body kit from an old ATV or develop your own - it all depends on the desire, financial capabilities and the availability of free time.
Do-it-yourself children's electric ATV is a pleasure for adults and a joy for a child from owning a unique personal transport. published
Any ATV experiences a lot of stress when driving, and therefore, to ensure the proper conditions for movement, manufacturers try to create the frame that is as strong as possible. It is the frame that must withstand not only the weight of the ATV and the driver, but also sharp falls and maneuvers. The frame is created according to a special drawing, from well-known Japanese and Chinese companies, the frame is reliable and has an excellent functional design. But if it is not possible to buy a branded model, and the desire to ride off-road is great, we suggest making an ATV yourself, while some structural details will be no worse than foreign counterparts.
The dimensions of the ATV frame usually differ depending on the technical properties of the model. If the equipment has a simple engine and it must withstand the load of 1 person, a small, strong frame will be optimal. For example, the frame of the Stealth 800 ATV has a length of 2,088 mm and a width of 1,213 mm, which is already an excellent indicator. But another representative of the Irbis 200U received a length of 1,760 mm and a width of 1,060 mm. That is, the difference is significant.
In addition to these requirements, the frame must be welded and constructed of durable materials. Usually, round steel pipes and metal profiles are used, they are best withstand heavy loads. If you bought equipment of a certain brand, then regardless of technical characteristics the frame must have mandatory design features... Also, many people wonder where is the frame number on the ATV? It must be mandatory, so there is no standard location. Usually try to look for the frame number under the seat, many have it on the front at the bottom. Others advise looking at the frame number on the right side under the front arm. It is imperative to find the frame number, without this data you will not be able to register your ATV.
DIY ATV frame
If you decide to create a four-wheeled all-terrain vehicle with your own hands, the first thing to do is to create a frame. Experts advise using frames from the Urals and the Oka car, they lend themselves better to changes. If you do not have the specified technique, use standard schemes and create an ATV frame from steel pipes and metal profiles. Sometimes, if you have a Ural motorcycle around its frame, you will additionally have to install a homemade frame. This is a big plus when creating an ATV, because it is possible to install a native Ural engine on a motorcycle frame, and an additional frame will create the design of a real ATV. If you do not know how to weld an ATV frame, first study the diagram below. After that, you can consult with a welder or mechanic who can quickly weld all the parts for you.
As you can see, the ATV frame diagram below is quite standard and has a simple design, the main thing is to carry out all the processes correctly. In the case of using a frame from the Urals with an additional frame made of pipes, such a design will be much simpler. The fact is that the motorcycle frame will already have a finished box, engine and other elements without additional welding, and the installed frame will directly hold the wheels and the driver.
At first glance, it may seem that assembling a homemade ATV is not an easy task. In fact, everything is much simpler than it seems, if there is necessary spare parts and tools. An off-road vehicle of this type is usually constructed from parts found on any unused motorcycle that is in decent working order.
Required set of tools
To assemble the device with your own hands, you may need the following tools:
Welding machine.
Bulgarian.
A good set of box and socket wrenches.
Other small tools like pliers and screwdrivers.
To assemble an ATV, you will need a small room with good lighting and heating. If you assemble in the summer, you can sit under a canopy.
Engine and transmission
Engines from Soviet-made motorcycles such as "Ural" or "Dnepr" are suitable as a power unit for a home-made all-terrain vehicle. For lighter and more maneuverable vehicles, you can use units from motorcycles like "Java" or "IZH", which were equipped with single-cylinder two-stroke engines.
To simplify the design of the future ATV, together with the engine, it is better to use the same transmission and drive with which they were originally equipped. To construct a machine with four-wheel drive you will need to install an additional gearbox. This is extremely rarely used in home-made devices, since it will be difficult to implement an additional unit without a sharp addition in weight at home.
Frame and suspension
The frame for a homemade apparatus is usually made by yourself from scratch. You can use blanks from an old motorcycle as material for the frame. The pipes from which they are made are lightweight and have the necessary strength and flexibility. As a last resort, you can choose the material yourself. Here the main parameter will be weight. Excessively thick tubes or profiles will make the ATV very heavy and overwhelming for fast and agile riding.
As a suspension, you can use shock absorbers with springs from the same motorcycles. The suspension itself is made in the form of the letter "A", and is movably fixed to the frame. Shock absorbers and springs should be selected so that they can support the weight of the future machine and provide a smooth ride with good control over bumps and holes.
Steering and wheels
Steering partly you can use a motorcycle, with the addition of two-wheel drives. The drive is carried out by adding levers and ball joints to the design, which can be borrowed from the car. The main task of the steering is precise and comfortable steering.
The wheels for an all-terrain vehicle are best used from a car, as they are wider and will increase the vehicle's cross-country ability. The diameter of the wheels must be calculated in such a way that the homemade ATV can develop sufficient speed and also has a harmonious appearance.
Body and electronics
For installation attachments, gas tank and controls, you can use a motorcycle frame, which is structurally connected to the ATV frame. In this case, special attention should be paid to the stability of the all-terrain vehicle, its appearance and the convenience of the driver's landing.
Do not forget about installing all the necessary lighting and outdoor alarms on a homemade ATV. Headlights, taillights and the direction indicators are perfectly usable from the same bike that everything else was taken from.
See what a homemade ATV is in use!
An ATV is virtually any four-wheeled vehicle, since the Latin word for "quadro" is "four". In the CIS, this name most often means four-wheel drive, representing the symbiosis of a motorcycle and a car. From a motorcycle, the ATV took over mobility, maneuverability, lightness, speed, and from a car - excellent characteristics of cross-country ability, power and controllability. The result is a unique vehicle designed for a variety of purposes.
The domestic market provides only foreign models of ATVs, the cost of which is often transcendental. At the same time, on secondary market transport, you can easily find used motorcycles and cars at an extremely low price.
For example, a motorcycle "Ural" - large, bulky, heavy and "gluttonous" has an excellent four-stroke engine with reverse gear and costs "a penny". For this reason, it is much cheaper and more fun for enthusiasts to create their own designs for these SUVs.
The quintessential factory ATV is shiny, neatly built, sturdy and powerful.
Its homemade counterpart, which is not much inferior in appearance, and even more so in terms of power.
How to make an ATV with your own hands
Before starting the assembly, it is necessary to draw up a detailed list of units and parts that will be needed to create your own brainchild, develop a work plan and a design drawing.
Engine: the best choice
It is logical that first of all it is necessary to find the "heart" of the future "beast" - power unit... Absolutely anything will do, from a conventional walk-behind tractor to a six-liter V12 - there are such precedents. In most cases, motorcycle engines are used - they are economical and small.

To use high gear ratios under normal operating conditions, a Minsk or Ural engine will suffice. In the summer, the issue of overheating arises, so you should choose models with air cooled... Another good option is boxer engines Soviet-made, an indisputable plus of which is a powerful traction and completely unpretentious cardan transmission.
Suspensions: rear and front
There are two most common solutions rear suspension for ATV.
- Gear-cardan system. The design is as lightweight and simple as possible, but there is no differential, which, in principle, can be sacrificed for the sake of the previously mentioned advantages.
- Using a road bridge. The construction turns out to be extremely heavy, and if there is no desire to have an ATV with a car base, it is necessary to shorten the bridge, which is a very non-trivial task. Of the advantages, it is worth highlighting only the presence of a differential, which is useful when driving on highways.
There are tremendous possibilities for creating front suspension and steering. The suspension arms of an ATV carry a significantly lower load than automobile ones, respectively, they can be made independently, using available tools for this. The best option- creation of a suspension based on the existing Ural motorcycle.
Frame: drawings and alternatives
The best solution is a solid construction made of pipes or profiles welded together.
Ideal - remove the frame from the donor motorcycle and weld necessary elements- this eliminates a number of problems, but the design may turn out to be unnecessarily complex.
Assembling the ATV
Having prepared necessary tools, vehicles-Donors and freeing up time, you can start creating your own ATV:
Thanks to its reliable, time-tested design, excellent power and traction, the Ural motorcycle is the most popular donor for homemade ATVs.

As you can see, using the outdated and inexpensive achievements of the Soviet car industry, you can create amazing machines that will amuse your vanity and satisfy most transport tasks.
Today we will talk about how to make yourself out of a motorcycle, walk-behind tractor or moped real ATV do it yourself. We will also consider drawings, diagrams and methods for assembling a homemade ATV from scrap materials in the garage
From a motorcycle of the "Ural" type - this big, bulky, heavy and "gluttonous" beast has a wonderful four-stroke engine with reverse gear and is worth a "penny". For this reason, it is much cheaper and more fun for enthusiasts to create their own designs for these SUVs.

It is ideal to remove the frame from the donor motorcycle and add the necessary elements - this eliminates a number of problems, but the design can turn out to be unnecessarily complicated.
Having prepared the necessary tools, donor vehicles and freeing up time, you can start creating your own ATV:
We collect the frame (frame). We connect the prepared metal beams, according to the drawing, to each other using spot welding. We check the structure and carry out solid welding. Alternatively, you can simply remake the frame from the donor motorcycle - it will be no worse.
Installing the engine. It can be installed both from the back and from the front - the main thing is to firmly fix it with bolts on the bottom of the frame.
We mount the drive and transmission to the rear wheels. The drive does not need to be created independently - it goes with the engine from the donor transport and is installed on the frame. Again, the drive and transmission must be properly secured to the frame to prevent backlash.
The steering is also installed from the motorcycle. Together with the steering wheel, it "migrates" to the ATV and fuel tank... In general, if you imagine the structure, it will look like this: 3/4 of the ATV is the same "Ural" or another motorcycle, 1/4 is homemade frame and suspension. ...
We install wheels from a small-sized vehicle ("Oka" or "ZAZ-968"). The rear wheels can go to an ATV together with the rear axle of the car, or they are attached as follows: we take ready-made axles with discs, and then we attach a gearbox to the rear for the drive. and install wheels on the disks
With a gearbox on the rear axle and an engine, we assemble a single drive (again, it will be easier if it is completely rearranged from the donor tool). We do it as follows: from the engine we pull the chain onto the gearbox and fix it, after which we carry out a performance check. Finally, we fix the whole structure on the frame.
Front suspension - independent - it is more profitable in terms of time and money, because all-wheel drive ATV requires significant revision of this unit by a professional turner, welder and electrician, which will take a very long time. Alternatively, we purchase ready-made factory units for ATVs.
Thanks to its reliable, time-tested design, excellent power and traction, the Ural motorcycle is the most popular donor for homemade ATVs.

You will also need spring dampers for the rear and front suspensions.
Engine for ATV:
Now you need to securely attach the engine to the frame. The engine is best used from a moped. After screwing it to the frame, connect the motor shaft to the gear on the rear axle with a simple chain drive. After that, bring all engine controls to the steering wheel and secure the pedals and levers to your frame.
The best and easiest way to make parts of the body kit or bodywork of an ATV is fiberglass. After manufacturing on wooden or plasticine blanks, the elements of the aerodynamic body kit are adjusted relative to each other, polished and then painted in the desired color, after which they are already attached to the ATV frame. Ideas, as well as some ready-made elements, for example from a broken car (of course, if you have them available), options for an external body kit can be taken from any serial models.
Important:
Remember that in order to operate the ATV on public roads, you will need to register it with the traffic police, where it is necessary to register any vehicles with an engine over 50 cc and a maximum design speed of over 50 km / h. Therefore, we recommend not to use engines larger than fifty cubic centimeters.
The frame for the ATV is welded using round pipes, corners and square profiles. At the same time, it is advisable to use elements of various mopeds and motorcycles, because it is there that pipes with high strength are used. Never use water pipes. They do not have the required strength and can crack at any time. Then we weld on the mounting brackets and fix the engine to the frame. Make your first ATV out of a moped engine
Even your children will like it, who will simply be delighted with it. The fact is that petrol-powered ATVs for kids are a great toy for every child. After all, he does not develop huge speeds, but the guys will have more than enough emotions from overcoming rough terrain. Next, we connect the engine shaft to the rear axle gear using a chain.
We install the ATV control mechanisms on the steering column, and attach the pedals and levers to the frame. The power supply and ignition system is taken from the same moped model from which we took the engine. Over time, they can be improved and refined within reasonable limits, of course. You can choose a fuel tank of the appropriate size. Do not forget also the point that in the question of how to make an ATV, each stage must be carefully worked out. Therefore, installing a battery on such a car is simply necessary.
You also need parts for assembling an ATV:
1 - disks from a scooter tourist or ant
2 - rubber for motoblock 10 inches and wider 4.5 or 5.0
3 - profile pipe 15 * 15. 17 * 17. 20 * 20. 25 * 25.
4 - bearing 306 - 12 pieces
5 - CV joint outdoor vase 2109-08 16 pieces, 4 of them are new 4 used, but workers, and 8 can be killed (for any hundred in scrap metal) and 8 anthers.
6 - engine with a moped at least 150 cc. for example, a viper storm in a place with a wiring with an ignition switch with a wheel and a glushak
7 - reducer from a motor scooter ant reinforced (all shafts on bearings)
8 - four leading sprockets from 21 tooth Izh and two new chains
9 - ball joints with Renault 21 for any disassembly with a shaft and a penny
10 - jet thrust rear axle(short.) from 2101 need-6 pieces
11 - a bunch of different bolts of cutting wheels and electrodes, well, that's all along the way
12 - shock absorbers of the Yamaha ario smoped -4 pcs from Honda Lead 2 pcs and 8 more killed shock absorbers from any yap mopeds (we will cut off the ears from them)
.
In winter, the ATV can be easily converted by replacing the rear wheels with pneumatics and installing a steering ski in front; the car thus turns into a snowmobile, and the transformation takes less than an hour. The use of available materials in the manufacture of the all-terrain vehicle, the simplicity of the design may well ensure the repeatability of the machine even in a home workshop.
The MTS frame is made of round tubes, square profiles and corners. It features detachable connections that allow you to remove the steering column assembly when installing the engine, as well as the front axle beam. Each of the connectors consists of a conventional "water pipe" sleeve, squeegee and locknut.
To tension the chain connecting the engine with the gearbox, the motor frame (part of the frame of the Minsk motorcycle) is moved; the axle of the rear wheels with bearings also has the ability to move in the longitudinal direction, which allows you to adjust the tension of the second chain connecting the gearbox to the rear axle. Front and rear fenders are removable (they are not available in the version of the snowmobile). The frame elements were joined by electric welding.
The engine of the motor vehicle is from the Minsk motorcycle, I have no comments on its operation. It is possible, of course, to install more powerful engines - from the Voskhod motorcycle or the Tula scooter; it is only necessary to adjust the dimensions of the frame for them. The choice of the "Minsk" engine was due to its efficiency and low weight. Its power turned out to be quite sufficient for trips on a snowmobile with a passenger, it is also possible to tow a skier or sled. The starting properties of the motor in summer and winter are quite satisfactory.
The directional control of the summer version of the motor vehicle is provided by turning the front wheels using two rods; for the winter version, there is a lever and a rod connecting it to the ski fork. The latter is borrowed from a moped. Front axle- from the SZD motorized carriage, however, somewhat reduced: sections are cut out of its beams and the central parts (with the torsion bolt) are welded to the peripheral ones (with the suspension arm bushings). In the winter version, the levers steering knuckles, rods and torsion bars are dismantled.
The steering wheel is from the "Tourist" scooter, it fits perfectly with the steering shaft with an M10 bolt. The controls are standard, motorcycle. The brake lever is connected by a cable to the brake shoes mounted on the gearbox.
Reducer. Its basis is the hub of the rear wheel of the Tula-200 scooter, to which an asterisk is welded from the side of the brake drum. The rear axle is driven by a chain with a 19 mm pitch. The transmission brake makes the rear axle much simpler. The sprocket on the axle is fixed with an M14 bolt, the hubs of the travel wheels are similarly attached, as shown in the drawings. As the basis of the gearbox, you can use not only the hub of the "Tourist" wheel, but also other motor vehicles.
The axle of the driving wheels is a rod with a diameter of 30 mm; its ends are turned to Ø25 mm, turned hubs are put on these places. Wheels are used from a motorized carriage with a size of 5.00X10.0. Winter wheels conventional for pneumatic tires on tires low pressure designs: with plywood discs, aluminum cradles and camera straps. The axle bearings are double-row, they have tapered inserts with nuts, which fix the axle well and do not require high machining accuracy.
More information about ATVs can be found at this link:
Optional equipment. This includes front and rear racks, headlights, turn signals and brake lights; their attachment points are shown in the figures.
The design of the all-terrain vehicle is simple, it can be made in just a few days in a fairly primitive workshop - of course, if all the components are available. And the possibilities of using such a machine are the widest: as a winch when plowing a vegetable garden, to drive a circular saw, as a simple garden tractor (excellent cross-country ability, therefore cultivation, hilling, etc. is possible). In addition, cross-country ability can be increased by installing twin rear wheels. You can also mount a reverse gear from the SZA motorized carriage, in which the differential is replaced by a shaft, and then the all-terrain vehicle will receive reverse gear. Rubber wear due to the lack of a differential is not observed, and this does not affect handling.
