The invention discloses a novel bicycle labor-saving structure. The structure is based on a bicycle frame, a bicycle handlebar, pedals, accessories, and wheel axles connected to wheels. A lever fulcrum element 2 is designed in the middle of a novel bicycle frame element 4, and lever force arm elements 1 and 3 are installed. The lower endpoint of the force arm element 1 of the upper fulcrum of the element 2 is connected in a rotatable manner with the front endpoint of an element 5, and the rear end of the element 5 is connected with a rear wheel axle and a real wheel connected therewith. The rear wheel is connected in a rotatable manner to the bicycle frame element 4 via the upper ends of elements 8 and 9, and the lower ends of the elements 8 and 9 are connected with the rear wheel axle and the real wheel connected therewith. The rear end of an element 6 is connected in a rotatable manner to the rear end of the bicycle frame element 4 through an element 7, and the front end is in rolling connection with the upper endpoint of the element 3. When the elements 6 and 12 are pressed, the upper and lower fulcrums of the element 2 make the lever force arm elements 1 and 3 pull the element 5 and the rear wheel, and the element 9 assists in pushing, thus making labor-saving walking of a bicycle implemented perfectly.
