A dead-corner-free bicycle capable of saving effort is composed of a bicycle body steel frame, a fluted disc, pedals, a front wheel and a rear wheel. The bicycle is characterized by further comprising interactive cables, U-shaped rings, limiting blocks and other components, the middle of a fluted disc pedal circular shaft is round, splines and spiral steel shafts with a diameter of 20 mm are arranged at the two ends of the fluted disc pedal circular shaft, and a steel bowl bearing is a 204 ball bearing. The fluted disc is installed on a spline at the right end of the bicycle, and a ratchet wheel power arm provided with a spline facing rightward is installed to serve as the right pedal which is tightened with a flat gasket, a spring gasket and a nut after being installed. A ratchet wheel power arm provided with a spline bent leftward is installed on a spline at the left end of the shaft to serve as the left pedal which is tightened with a flat gasket, a spring gasket and a nut after being installed. The ends of the left pedal and the right pedal both face forward, and the U-shaped rings used for installing the interactive cables are welded between the pedals and ratchet wheel shafts. By the adoption of the bicycle, effort and labor are saved, dead corners of force are eliminated, and the effect of developing strong points and avoiding weak points is realized. The bicycle is the optimal technical scheme of manpower-driven bicycles except motor vehicles and electric vehicles.
