[0002] The flywheel of a bicycle is a disc-shaped metal part. It is located on the rear wheel axle and is connected to the tire. The flywheel plays a very important role in a bicycle. When a rider pedals, it can drive the rotation of the rear wheel, thereby pushing the bicycle forward. In addition, the energy storage function of the flywheel can also make the riding more stable. When the rider stops pedaling, due to the inertia of the flywheel, the rear wheel will continue to rotate for a period of time, so that the bicycle can continue to move forward instead of stopping suddenly. When the user uses the bicycle flywheel, the user needs to ensure that it has a wedge roller itself.
