摘要： A driving mechanism of the present invention includes a transmission disc, a transmission belt, a pair of cranks, a pair of arms, a pair of connecting bodies and a pair of pedals. The cranks and the arms are disposed on the frame of a bicycle, and the connecting bodies are disposed between distal ends of the cranks and the arms. Each pedal is disposed on the connecting body and is movable in an orbit. A vertical distance between the topmost point and the bottommost point of the orbit is H, and a horizontal distance between the front most point and a rearmost point is W, which satisfies the following relationship: H/W≧5/3.
