The invention relates to a laborsaving bicycle utilizing a rider dead weight. The laborsaving bicycle comprises a bicycle and is characterized in that a gear box is mounted at the back part of the bicycle; an output shaft of the gear box is connected with a back wheel; a pair of pedals are arranged on the left and right sides of the bicycle; each pedal is connected to an input shaft of the gear box via a long arm; the tail end of the long arm is connected with the input shaft via a unidirectional ratchet; a return spring is connected to the long arm; the left and right long arms are connected with each other via a connection belt; the connection belt is wound on a pulley; the output shaft of the gear box is in a connection with a back wheel shaft via a unidirectional ratchet; the output shaft of the gear box is connected with a gear on a back wheel loop via a unidirectional ratchet. The laborsaving bicycle utilizing rider dead weight has the advantages that the bicycle is driven to advance forward by utilizing the rider dead weight, and labor-consuming leg pedaling is avoided.
