The present invention relates to a standing bicycle. The standing bicycle comprises: a frame portion supporting front and rear wheels to be able to rotate and having a steering shaft vertically disposed in the front; the front wheel rotatably coupled to the front of the frame portion; the rear wheel rotatably coupled to the rear of the frame portion; pressure pedals disposed on both sides of the frame portion and moved vertically by the pressure alternately generated by both feet of a user; a motion converting portion converting vertical movement of the pressure pedals into rotational motion; and a rear wheel driving portion transmitting the rotational motion converted by the motion converting portion to the rear wheel. The rear wheel driving portion comprises: a chain driving gear coupled to the motion converting portion to be rotated; a chain driven gear coupled to a rotary shaft of the rear wheel; and a chain coupled to the chain driving gear and the chain driven gear and transmitting rotation of the chain driving gear to the rear wheel. The motion converting portion comprises: a pair of connecting arms respectively coupled to both ends of a rotary shaft of the chain driving gear; and a pair of pedal coupling connecting rods, each of which has one end coupled to each connecting arm and the other end coupled to each pressure pedal. According to the present invention, the bicycle is driven while the user is in a standing position, such that stability of the bicycle can be enhanced, and thus it is possible to reduce physical burden of the user.

    본 발명은 스탠딩 바이크에 관한 것으로서, 전륜과 후륜을 회전가능하게 지지하며, 전방에 조향축이 수직하게 구비되는 프레임부와; 상기 프레임부의 전방에 회전가능하게 결합되는 전륜과; 상기 프레임부의 후방에 회전가능하게 결합되는 후륜과; 상기 프레임부의 양측에 사용자의 양발에 의한 교번적인 가압에 의해 상하로 이동되는 가압페달을 구비하며, 상기 가압페달의 상하이동을 회전운동으로 변환시키는 운동변환부와; 상기 운동변환부에 의해 변환된 회전운동을 상기 후륜으로 전달하는 후륜구동부를 포함하되, 상기 후륜구동부는, 상기 운동변환부에 결합되어 회전되는 체인구동기어와; 상기 후륜의 회전축에 결합되는 체인종동기어와; 상기 체인구동기어와 상기 체인종동기어에 결합되어 상기 체인구동기어의 회전을 상기 후륜으로 전달하는 체인을 포함하되, 상기 운동변환부는, 상기 체인구동기어의 회전축의 양단에 각각 결합되는 한 쌍의 커넥팅암과; 일단은 상기 커텍팅암에 결합되고 타단은 상기 가압페달에 결합되는 한 쌍의 페달결합커넥팅로드를 포함하는 것을 특징으로 한다.
