The invention discloses a reciprocating type pedal power mechanism of a bicycle. The reciprocating type pedal power mechanism comprises a fixed sleeve fixed to a bicycle frame, a movable sleeve rotationally connected into the fixed sleeve in a sleeving manner and an inner shaft rotationally connected into the movable sleeve in a sleeving manner. A first pedal unit and a first ratchet are arranged at positions, protruding out of the fixed sleeve, of the movable sleeve; a first resetting mechanism used for resetting the first ratchet is arranged on the movable sleeve; a second pedal unit and a second ratchet are arranged at positions, protruding out of the movable sleeve, of the inner shaft; a second resetting mechanism used for resetting the second ratchet is arranged on the inner shaft. As the structure is adopted, wheel discs are driven to advance when pedals are stamped, the pedals are reset to original positions under the action of the resetting mechanisms after force is removed, and thus the reciprocating type pedal process is realized. The problem that the traditional pedal mechanism can pass the zero power arm position by using the inertia is solved, and climbing and cycling are easier.
