1. A self-powered apparatus, being a pedaling and rotating apparatus for cycling, comprising:
a pedal unit comprising an inner surface to form an accommodating space therein;
a spindle accommodated in the accommodating space and comprising a body portion and a base portion, wherein the body portion is disposed closer to at least one pedal plate of the pedal unit than the base portion thereto;
a generator comprising a stator and a rotor, wherein the stator is disposed on the spindle, the rotor is disposed on the inner surface of the pedal unit, and the rotor surrounds the stator correspondingly and is non-contact with the stator;
an energy storage element electrically coupled to the generator and disposed adjacent to the base portion, wherein the energy storage element is surrounded by a spindle inner surface of the base portion;
at least one sensor being power-supplied by the energy storage element and disposed adjacent to the base portion; and
at least one circuit board disposed around the base portion, wherein the at least one circuit board supports a rectifying circuitry for the energy storage element and a supplying circuitry for the sensor;
wherein when the pedal unit is being pedaled to rotate by a rider, the stator is fixed on the spindle, the rotor rotates relatively to the stator and along with the pedal unit, and a generated power is generated by the generator to charge the energy storage element.
