The invention discloses a multi-force-point lever type double-drive bike. The multi-force-point lever type double-drive bike comprises a front wheel, a rear wheel and a bike body support and further comprises a pair of lever type driving devices supported by the bike body support, and a switching wheel set is further arranged between the pair of lever type driving devices and the rear wheel. The pair of lever type driving devices comprises a lever assembly, stressed parts, a crankshaft assembly, a stop point passing assembly, stressed part tension springs and a lever assembly tension spring. The bike is novel in structure, a rider applies force downwards from the long end of a lever, circumferential movement is not needed, treading frequency is reduced, physical strength is reduced, frequency is improved, and the riding mode is unique. The lever assembly serves as the labor-saving lever and makes multi-point contact with the stressed parts, and it is guaranteed that the treading travel of the feet of the rider is short while labor is saved; double driving is adopted, and therefore driving force is powerful, and efficient running can be achieved.
