When assembling the bicycle, it is only necessary to connect the fixing member of the fixed base to the bicycle braking system. When the vehicle is braked, the bicycle braking system pushes the displacement of the fixed base, and then drives the power generating roller to press down to contact the wheel of the bicycle, and the power generating roller and the bicycle wheel contact and friction to generate rotation to generate electricity. It can be seen that the power generating device can be easily integrated into the existing bicycle braking system, and the original structure is not affected at all, and the riding comfort can be maintained to achieve the object of the present invention.

The aforementioned fixed base can be further connected with the brake skin, so that the brake skin is integrated with the power generating device, and the assembly is more convenient.
