The invention provides a bicycle with elastically-resetting ratchet pedals and an operating method of the bicycle. The bicycle acts through the gravity of a standing body, has the advantages that driving force is large, power conversion efficiency is high and the pedals reset elastically, is higher in speed and multiplied in activity radius and meets the requirements of people for riding the bicycle easily, conveniently and rapidly within a large activity radius in a green and environment-friendly mode. The two ratchet pedals are horizontally symmetrical, are parallel in the same direction, and are installed on the two sides of a front half circle of a large chain wheel at the same inclination angle. Ratchet ends are fixed to a middle shaft at the rotation center of a large chain plate. Pedal ends do vertically-reciprocating circular motion around the middle shaft to drive the bicycle to move. The ratchet pedals are connected with elastic pieces fixed to a frame and are driven by the elasticity of the elastic pieces to reset to the initial positions after stopping acting.
