A lever bicycle comprises a flywheel, gears, a center shaft, cranks, pedals, pressure bars, ball bowls, balls, ball baffles, an outer wheel, chains, chain wheels, chain wheels with spikes, bearings, semi-annular fixing plates, a rear shaft, a spring sub wheel, a locking spike and circumferential pressure cranks. The lever bicycle is technically characterized in that the pedals on the left side and the right side of the center shaft are connected with the cranks, and the pedals are connected with the pressure bars through the ball bowls, the balls and the ball baffles; the circumferential pressure cranks are integrated with the bearings and are connected with the chain wheels with the spikes through bearing internal threads; the spike heads of the chain wheels with the spikes are connected and fixed through the pressure bars; the chain wheels and the bearings are welded into a whole; the bearing internal threads are connected with rear shaft threads; the chain wheels and the chain wheels with the spikes are connected through the chains; the gears and the rear shaft are connected in a threaded mode; the semi-annular fixing plates, a bicycle frame and the chain wheels are fixed into a whole; the locking spike is welded to the left semi-annular fixing plate; the gears and the bearings are fixed on the locking spike; the gears and the flywheel are fixed on a central round pipe of the spring sub wheel which is connected with the outer wheel through a spring. One bearing is arranged in the central round pipe of the spring sub wheel and connected with the rear shaft. Labor and time are saved, and speed is high.
