The invention provides a labor-saving structure of a bicycle, and belongs to the technical field of bicycles. The labor-saving bicycle solves the problem that an existing labor-saving bicycle is poor in stability. The labor-saving structure of the bicycle comprises a middle shaft arranged on a bicycle frame in a penetrating mode, two fixing discs, two pedal rods and pedals connected to the outer ends of the two pedal rods respectively, the two fixing discs are both in a disc shape and vertically fixed to the two sides of the bicycle frame, and the two ends of the middle shaft penetrate through the eccentric positions of the two fixing discs respectively. The labor-saving structure further comprises two annular rotating rings arranged on the outer sides of the two fixing discs in a sleeving mode respectively and two connecting pieces perpendicularly fixed to the two ends of the middle shaft, the rotating rings can rotate in the circumferential direction relative to the fixing discs, and the two connecting pieces are each provided with a cylindrical sliding sleeve. And the inner ends of the two pedal rods penetrate through the two sliding sleeves correspondingly and are connected to the two rotating rings correspondingly. The labor-saving structure of the bicycle has the advantage of being good in stability.
