Homemade tricycle IZH Jupiter-5
This tricycle based on Jupiter-5 was assembled by the village “homemade craftsman” Vitaly Borovskoy. This wheel arrangement allows the motorcycle to behave stably in complete off-road conditions, which provides quite comfortable driving conditions in contrast to its two-wheeled counterparts.
The motorcycle remains practically unchanged, only the rear wheel is sent for replacement, instead of which a gearbox with axle shafts from the Ant cargo scooter is installed. But in this case, the author took a rather unconventional path and made homemade axle shafts from scrap, ordering splines to be bored to the standard size from a familiar turner .
The rear wheels and hubs are from the domestic VAZ car; in the winter and snowy seasons, for better traction with the road surface, the author puts chains on the wheels, thus the cross-country ability of the tricycle increases many times over.
It is advisable to install forced air cooling, because the load on the engine with two rear wheels is slightly higher than in the standard configuration. The problem of overheating of aluminum cylinders of a motorcycle engine is solved by installing an electric motor with the ability to pump air (a motor from a car heater) is connected to the on-board network of the tricycle and air is supplied to the cylinder heads through corrugated bells.
And so let's look at the design features of a homemade tricycle assembled on the basis of the Soviet motorcycle Jupiter-5
The tricycle is stable and you can easily ride it off-road. Putting chains on the rear wheels increases cross-country ability.
Having settled the motorcycle in the spring snow along the very axle shafts, the movement still continues, but the main thing here is not to overheat the internal combustion engine until forced cooling is installed.
He doesn't care about the spring thaw.
Not every person can find a vehicle to suit their own taste - especially if he wants something unusual. Therefore, it is worth thinking about the fact that you will have to do everything yourself - this is the only way out, but it is also the best one if you understand mechanics and know a lot about assembly. But what can you put together on your own that will surprise everyone around you? A great example of this would be a tricycle - you can't buy them in stores, they are rarely mass produced, so you can create your own unique vehicle that will be the envy of everyone around you. However, a serious question arises here - how to make a tricycle with your own hands? To do this, you will need a wide variety of spare parts that you can get, while using the base and parts of one of the available motorcycles, such as the Ural or Izh. Chances are you have one of these in your garage. They can be easily converted into a tricycle or used to assemble your own unique model from scratch. Accordingly, you will need to think through everything in advance, make a drawing or download it from the Internet, because there are definitely enough enthusiasts like you on the network. And then you need to prepare for long and not the easiest work, which a few tips can make easier. You can read them further.
The simplest trike from the Urals
Hi all! I don’t know how to write a lot and beautifully, so the text is small, well, more photos) Actually, when I first saw the trike from KBMTS “Irbit Blues,” I really liked it because the design is very simple and the budget for construction will be small. The thought “we need to build” stuck in my head, but then there was neither the time nor the opportunity, and maybe the intelligence would not have been enough to master it all (I was still in school). But time passes, this is already the 5th year of teaching. Institute, you need to write a diploma. A classmate had a topic about something related to club activities and it would be desirable to make applications (my topic, unfortunately, or maybe fortunately, was done without applications at all), he was offered to assemble a uni-moto, but I received a proposal for a trike. The Ural still stood idle for 3 years, and yet another look at the blues did not give me peace. Since the deadlines were tight and the budget was small, let’s just say this type was just for us. The solution was - build! but not the same, but simpler.
A few characteristics: Engine M-67 standard, only air filter from M-2141 Bridge VAZ-2107 with GP 3.9 Brakes: rear - hydraulic (the role of the GTZ is played by the clutch cylinder M-412), front - none Wheels: front - Izh R18 , rear - now R13, but put any) The frame is standard up to the rear stud of the internal combustion engine, after that there is a 40mm pipe 4mm wall, at the bends inside there is another pipe.

Tricycle layout
The first thing you need to think about if you are going to make your own trike is its layout. The fact is that the power unit, which is usually located directly on the axle of motorcycles, thereby improving the balance and reliability of the vehicle on the road, can no longer be there. Accordingly, you need to carry it by the axle, between the two rear wheels. Naturally, this affects the stability and controllability of the tricycle - and not in the best way. But if you are an experienced driver, you will be able to adapt quite quickly. Moreover, this opens up some interesting prospects - for example, the ability to rear up your vehicle without any problems when developing at high speed. It looks extremely impressive and, unlike motorcycles, in this case you do not risk anything - this is an absolutely safe action (of course, if you do not pull the car too much, but on a motorcycle such a trick is much more difficult in any case). Accordingly, you will be able to impress everyone around not only with the appearance of your vehicle, but also with its spectacular capabilities. This alone is enough to convince yourself to make a tricycle with your own hands.
Power unit
Naturally, when you think about making a tricycle with your own hands, you will need to choose a suitable engine. In this case, you do not have to take a power unit from another motorcycle - an engine from a car will also work. The main thing is that it fits properly between the rear wheels. This way you can improve the performance of your vehicle. In some cases, you won’t even have to make any changes or improvements; in others, you won’t even have to replace the radiator or some other part. It is also recommended to install other mufflers, and increase their number by installing one on each cylinder. Naturally, there are other options - it all depends on which power unit you decide to choose. For example, if you make a tricycle from the Ural with your own hands, then it is better to replace the engine completely.
Beginning of work
You should prepare in advance for assembling the trike. You will need to find a ZAZ-968 and a Ural motorcycle at a disassembly site in decent condition. From ZAZ you will need an engine, from Ural - most of the components. You will have to make the frame yourself and this is the most difficult stage of the whole undertaking. As a result of manipulations, converting a Ural motorcycle into a tricycle can turn into a presentable, powerful vehicle, no worse than its factory counterparts.
The frame plays the role of a connecting link on which all the parts will be installed. It must be reliable and comply with the drawings. There are only a few nuggets that can produce a similar product with precision up to 5 mm; if you doubt your abilities, it is better to entrust the work to professionals. Before installing the parts, spend an hour and measure the frame with a tape measure, check the locations of the holes and clamps.
Gear box
When you make a tricycle from the Ural with your own hands, you definitely need to take into account where exactly the gearbox will be located. You already understand that the engine itself will be off the axle, behind the seat, between the two rear wheels. At the same time, make sure that it is attached as securely as possible in at least three places - especially if you plan to perform various tricks, as described above. As for the gearbox, it is better to install it on the left side of the steering wheel, since your right hand will be occupied most of the time. It is unlikely that if you take the engine and gearbox from a car, you will be able to make a design that is convenient enough to change gears without stopping driving. Also don't forget that you need to take care of connecting the box to the motor, which is a bit more difficult considering that it is now located a little further from the box than it should have been in the original. But if you're trying to figure out how to make a tricycle with your own hands, you always need to be prepared for these kinds of surprises and difficulties.
Suspension
It doesn’t matter whether you make a tricycle with your own hands from an Izh or any other motorcycle. You will have to remodel the front wheel suspension anyway. After all, the distribution of forces in a tricycle is very different from that observed in a regular motorcycle. To do this, you will need two pairs of consoles, as well as two powerful springs - if possible, try to get helicopter or airplane springs, but springs from passenger cars can also be used if necessary. The consoles need to be connected to each other by levers, through which the axle of your front wheel will pass. Naturally, this is not the only way - there are a large number of ways to make a tricycle with your own hands. Drawings are available on the Internet (one of them is in our article), but this method is one of the most effective.
Advantages and disadvantages
Let's start with the advantages that a homemade trike from a Ural motorcycle has: - excellent cross-country ability, especially in mud; - comfort and less fatigue; — simplicity, low cost and reliability of the design; — minimal risk of engine overheating.
The trunk allows you to secure everything you need
And now about the disadvantages: - difficult control (due to a blocked bridge); — lack of reverse gear, which would be very useful (to be solved); — the intake manifold is strongly cooled until condensation appears (possibly having a negative effect on the combustible mixture); — a large load on the front axle (the front wheel sinks in mud, which significantly worsens cross-country ability); — high speed in 1st gear.
If there was a reverse gear, there would be no need for a shovel
In general, these shortcomings can be considered insignificant, especially considering the significant improvement in cross-country ability. In addition, many of them can be eliminated.
Trike from the Urals
How the suspension works
If you are not making a trike out of a scooter with your own hands and are counting on a powerful and impressive model rather than a children's tricycle with a motor, then you need to seriously think about the action of your front wheel suspension. What are helicopter or airplane reasons for? The fact is that the movement of the wheel along the vertical axis will occur with much greater force than on a motorcycle, so you need to install stiff and durable springs - at least in the lower part of the suspension, which compensates for movement along the vertical axis. To compensate for movement along the horizontal axis, you can use softer springs - for example, from the Izh motorcycle. As you can see, assembling a tricycle with your own hands is quite difficult, but if you follow all the instructions, have a clear drawing and all the necessary materials, you should be able to cope.

The practicality of a trike is higher compared to the classic scooter layout. It’s true that its price is steep, so we suggest taking a used Honda scooter or any other used scooter as a basis and remodeling it yourself.
Battery
The battery for your tricycle must be installed under the driver's seat - for this purpose a special frame is created, located above the engine. This way, everything important about your vehicle is in one place. You should also consider making the passenger seat behind the driver's seat. Not only does it allow more people to ride at the same time, it can be attached with saddlebags that will completely enclose the engine and battery, making your trike complete.
