According to the present invention, a chainless bicycle comprises a pedal and a crank arm performing an up-and-down motion which allows a gear unit to rotate with a hub spindle of a rear wheel, wherein the gear unit is coupled to a hub of the rear wheel and the hub spindle and allows the hub and the rear wheel to rotate together, thereby, the bicycle can run forward smoothly. Thus, the chainless bicycle has reduced weight due to a simplified structure and reduced number of components.

    무체인 자전거는 페달 및 크랭크암의 상하운동에 의해 뒷바퀴의 허브축과 함께 기어부가 회전운동을 하게 되고, 상기 기어부는 뒷바퀴의 허브 및 허브축과 결합되며, 상기 기어부와 함께 허브 및 뒷바퀴가 회전함으로써 자전거는 원활하게 전방을 향해 주행을 할 수 있게 된다. 따라서 체인이 없는 구조를 갖는 자전거는 구조가 단순화되고 부품수가 줄어 무게도 줄어들게 된다.
