Abstract: A belt-driven generator essentially comprises a stator and a rotor. The rotor exteriorly includes a driving annular surface. With the driving annular surface, the rotor can be directly connected to the belt and driven by the drive unit, thus reducing vibration and noise while extending the service life of the generator. In addition, the part cost, the assembly cost and the assembly space of the generator can be reduced.

Abstract: A bicycle generator mounting structure comprises: a base, an adjusting member, a connecting member, and a flexible member. The adjusting member is disposed on and adjustable in position with respect to the base mounted on a bicycle frame. The connecting member is disposed on the adjusting member. The generator is connected to the connecting member via the flexible member which is capable of returning to its original shape after deformation, hence, the flexible member can absorb the noise caused when the bicycle is running and keep the generator in optimal contact with the wheel.
