Repair the missing rear gear system and how to disassemble and install the bike
Repairing the back system is important because of the maintenance of the steam and the repair of missing it with an easy method, so instead of changing it, we are going to work in the place of the stirrup. We put a small part of this wax in the ring, and you can make a thin pen zipper, cut a part of it and put it between the shaft.
