The present invention relates to a bicycle driven by the stepping operation of a rider. The present invention provides the bicycle driven by a step including: a bicycle frame wherein driving wheels are separately arranged in a front part and a rear part, and a crank is arranged in a middle part; steps of which one end is connected to one side of the bicycle frame by a rotary shaft, having a sliding hole horizontally formed in a middle part in a longitudinal direction, and separately arranged in both sides of the bicycle frame; first links, separately arranged in both sides of the bicycle frame, of which one end is fixated and connected to a central shaft of the crank, and the other end is extended to an outer circumferential side of the crank; a second link of which one end is connected to the other end of the first link to be able to rotate, and the other end is extended to the sliding hole; and a sliding rod connected to the other end of the second link, inserted into the sliding hole, and moving along the sliding hole. The bicycle driven by a step is capable of reducing the fatigue of the rider by reducing displacement in a Y-axis in comparison with an existing bicycle.

    본 발명은, 탑승자의 스텝 조작에 의해 주행하는 자전거로서, 전방과 후방에 각각 구동휠이 배치되고, 중간부에는 크랭크가 배치되는 자전거 프레임; 일단이 상기 자전거 프레임의 일측에 회전축으로 연결되고, 중간부에는 길이 방향으로 슬라이딩홀이 수평으로 형성되며, 상기 자전거 프레임의 양측에 각각 배치되는 스텝; 상기 자전거 프레임의 양측에 각각 배치되어 일단이 상기 크랭크의 중심축에 고정 연결되고, 타단은 상기 크랭크의 외주측으로 연장하여 배치되는 제1 링크; 일단이 상기 제1 링크의 타단에 회전가능하게 연결되고, 타단은 상기 슬라이딩홀로 연장되는 제2 링크; 및 상기 제2 링크의 타단에 연결되고, 상기 슬라이딩 홀에 삽입되어 상기 슬라이딩 홀을 따라 이동하는 슬라이딩 로드를 포함하는 스텝 구동 자전거를 제공한다. 본 발명은, 기존의 자전거보다 Y축 변위량이 감소되도록 하여 탑승자의 피로가 감소될 수 있다.
