PURPOSE: A bicycle equipped with a spring is provided to easily obtain driving force by using elastic energy stored in the spring as auxiliary power. CONSTITUTION: A bicycle(100) equipped with a spring comprises a frame(101), a pair of wheels(106,107), a saddle(105), a steering wheel(108), a pair of pedals(116,117), a power train(110), and an auxiliary power unit(130). A pair of wheels are coupled on the frame to be rotated. The saddle supports a user's body. The steering wheel controls the steering of the nose wheel. A pair of pedals supply the power of legs as bicycle driving force. The power train transfers the power of the legs to the back wheel. |
