Abstract
The invention discloses a bicycle, which comprises a handlebar assembly (1); an upright tube (2) having a first end fixedly connected with the handlebar assembly (1) and a second end rotatably connected with a front fork arm (6); a rocker arm (14) extending from the second end of the upright tube towards a front wheel, thereby forming a driving lever with the upright tube; a flywheel (8) mounted on the front wheel; and a cable (16) having a first end fixed to a position (7) where an end of the front fork arm (6) is located, and a second end trained in a pulley (15) mounted at the free end of the rocker arm (14) to be fixed at the flywheel (8) of the front wheel. The free end of the rocker arm is movable forward and backward with forward and backward movement of the handlebar assembly, thereby causing rotation of the flywheel (8) through the cable so as to drive the front wheel to rotate. Unlike the conventional bicycles which are driven to move forward by the rear wheel using pedals only, the present invention makes a breakthrough in increased speed of the bicycle and allows for a whole-body-exercise of the rider.
