Making a bike from scratch is a rather laborious task. To do this, you need to have the skills of turning and plumbing and have access to a workshop equipped with the necessary machines and tools. But it is quite possible for anyone to assemble a bicycle from ready-made parts.
It is necessary
an understanding of the complete set of a bicycle, skills in the selection and assembly of equipment
Instructions
Step 1
First of all, you need to develop a drawing of the bike being manufactured. To do this, it is better to use ready-made drawings that amateurs and craftsmen post on the Internet. If you have such design skills, you can create a drawing yourself.
This is a very important matter - it will be simply impossible to ride a bicycle made according to an incorrectly calculated drawing. In addition, if the balancing is incorrectly calculated, some of the connection nodes will be overloaded. This will lead in the future to the accumulation of metal fatigue, destruction or cracks at the joints of the parts. Or, to put it simply, the bike will fall apart at the most inopportune moment for you.
Step 2
Keep in mind that it is not possible to make wheels and a chain mechanism with drive and driven gears at home, so you will have to buy all these parts anyway.
After you have acquired a suitable blueprint, study it carefully. For the manufacture of the frame, metal tubes of different diameters are required. Purchase the appropriate material and proceed with each element separately. Check the workpieces for defects and cracks.
The manufactured elements are connected to each other into a single whole by means of spot welding.
Step 3
To make a fork, you need a small press machine and gas welding. You can use a forge and tools designed for forging metal.
When the frame and fork are nearly complete, you will need to drill holes for the drive sprocket in the frame and the wheel mounts in the frame and fork. The holes must be strictly perpendicular to the longitudinal axis of the frame and parallel to each other.
Step 4
Then you need to make a stem with a stem, a leather saddle with a seatpost, pedals. We attach all the parts to the frame, we hang the chain mechanism, wheels, brakes. Now you can start testing.
If the equipment keeps on the road with dignity, it does not lead to the side, the pedals rotate normally without additional effort, the bike is disassembled again and ready for painting.
If the ride is uncomfortable or any problems are revealed during the tests, you need to find and eliminate the possible causes. We repeat this procedure until the bike becomes a well-oiled and well-functioning single mechanism.
Step 5
But why make yourself so difficult when it’s easier to buy ready-made parts and assemble the bike you want?
You can assemble the lightest possible option. We buy a titanium or, if the budget does not allow, an aluminum frame. And we hang components on it, according to our own ideas about price and quality.
Wheel rims, spokes, tires, tires, eccentrics, steering stem, steering column, handlebars, hard or soft forks, brake pads, cables, brake levers and similar no less important parts - all this can be bought separately and independently of each other. friend.
Why such a "constructor" is convenient: at any time, parts that do not suit you or are out of order can be replaced with new ones purchased at the nearest bicycle store or ordered over the Internet.
