In practical applications, the generator set, the carrier and the brake unit can be integrated into one side plate, so that the generator set, the carrier, the brake unit and the side plate are integrated to present a modular structure.

Through the technical means adopted by the creation, when the user uses the fitness equipment to exercise, the driving force generated by the pedal mechanism passes through a transmission belt. And driving the flywheel to rotate, so that the genset generates feedback power, and the feedback power generated by the genset generates an output power to the braking unit via a power control unit, and the braking unit generates a magnetic field to be in the metal ring.
