A self-powered device, a bicycle and an indoor exercise bike, the self-powered device being a pedaling and rotating device for riding, the self-powered device comprising a pedaling unit, an axis, a generator and an energy storage element. The treading unit comprises an inner surface, and an accommodating space is formed in the treading unit. The axis is contained in the containing space. The generator comprises a stator and a rotor, the stator is arranged on the axis, the rotor is arranged on the inner surface of the treading unit, and the rotor correspondingly surrounds the stator and does not make contact with the stator. The energy storage element is electrically coupled with the generator. When the treading unit rotates through treading of a rider, the stator is fixed to the axis, the rotor rotates relative to the stator along with the treading unit, and the generator generates generated power to charge the energy storage element. Therefore, the service life of the energy storage element can be prolonged.
