The invention provides a bicycle labor-saving mechanism, belongs to the technical field of bicycles, and solves the problem that an existing bicycle labor-saving structure is low in stability. The bicycle labor-saving mechanism comprises a middle shaft, two guide rails with guide grooves and two pedal rods, the two ends of the middle shaft penetrate through the eccentric positions of the two guide rails respectively, the inner ends of the two pedal rods are connected with guide pieces clamped into the corresponding guide grooves, and the outer ends of the pedal rods are connected with pedals. The labor-saving mechanism further comprises two transmission pieces perpendicular to the middle shaft, the two transmission pieces are arranged at the two ends of the middle shaft respectively and fixedly connected with the middle shaft, each transmission piece is provided with a cylindrical sliding cylinder, the two pedal rods penetrate through the corresponding sliding cylinders respectively, and the sliding cylinders are located between the guide pieces and the outer end portions of the pedal rods. The bicycle labor-saving mechanism has the advantage of being high in stability.
