When the bicycle is moving forward normally and the drive motor 72 is not working, the rear hub of the bicycle drives the disc brake disc 1 to rotate synchronously. The disc brake disc 1 drives the ratchet disc 4 and the pawl 42 to rotate. During this process, the pawl 42 passes through each ratchet tooth 221 in turn, and the ratchet 22 and the gear disc 2 do not rotate. When the drive motor 72 works, the drive motor 72 drives the drive gear 71 to rotate.

When the drive motor 72 does not work and the bicycle moves backward, the disc brake disc 1 and the pawl 42 rotate synchronously. Due to the action of the pawl 42 and the ratchet 22, the pawl 42 drives the gear disc 2 to rotate, and the gear disc 2 also drives the drive gear 71 to rotate. At this time, the backward function of the bicycle is not affected.

[0096] In this embodiment, due to the adoption of the gear transmission method, the transmission efficiency is higher. Compared with the tire grinding type booster, it will not accelerate the wear of the tire. Compared with the booster using a chain as the transmission part, there will be no problems such as the risk of chain detachment or breakage and the design defect of pulling loose the spokes. At the same time, the gear energy transmission efficiency is also higher than the chain transmission efficiency.

[0097] And in this embodiment, the support box 61 can be disassembled and assembled quickly and conveniently.
