A bicycle having a vertically reciprocal driving device is provided to improve the driving force of the bicycle by driving the bicycle with vertical motion of a rider's leg without energy waste. A bicycle having a vertically reciprocal driving device comprise a frame(200), a fork(310), a handle bar(320), a wheel part, a vertically reciprocal driving device(400), and a power transmission(500). A saddle(210) is equipped at the upper part of the frame. A front-wheel(311) is fixed to one side of the fork to be rotatable. The handle bar steers the front-wheel. The wheel part comprises a rear wheel(330) supporting the frame. The vertically reciprocal driving device is positioned between the front-wheel and the rear wheel and converts the rider's reciprocation into rotational motion to drive the rear wheel. The power transmitter delivers torque transformed with the vertically reciprocal driving device to the wheel part. |
