The invention discloses a bicycle with pedals movably driving a ratchet wheel set along a guide rail. Wherein the middle rotating shaft mounting frame is fixedly connected with the saddle mounting column, and the torque middle rotating shaft is mounted in the middle rotating shaft mounting frame in a rotating connection manner; a first ratchet-pawl chain wheel group, a second ratchet-pawl chain wheel group and a pushing ratchet-pawl chain wheel group are mounted on the torque transfer shaft; the first guide rail and the second guide rail are both fixedly installed behind the saddle installation column, the first sliding block and the second sliding block slide in the corresponding guide rails respectively, and the first pedal and the second pedal are fixed to the first sliding block and the second sliding block respectively. The upper end of the first sliding block and the upper end of the second sliding block are connected with one end of a first driving chain and one end of a second driving chain respectively, the other end of the first driving chain and the other end of the second driving chain are fixedly connected with one end of a chain pull rope respectively, and the two driving chains bypass and drive the ratchet wheel, pawl and chain wheel sets respectively. The problem that due to the fact that the body types of operators are different, the optimal stress point cannot be adopted for treading and riding is solved.

    本发明公开了一种踏板沿导轨活动驱动棘轮组的自行车;其中,中转轴安装架与固接车座安装柱,扭矩中转轴通过转动连接安装在中转轴安装架中;扭矩中转轴上安装有第一棘轮棘爪链轮组、第二棘轮棘爪链轮组和推行棘轮棘爪链轮组;第一导轨和第二导轨均固定安装于车座安装柱的后方,第一滑块和第二滑块分别在各自的导轨中滑动,第一脚蹬和第二脚蹬分别固定在第一滑块和第二滑块上;第一滑块和第二滑块的上端分别与第一驱动链条和第二驱动链条的一端相连,第一驱动链条和第二驱动链条的另一端分别与链条拉绳的一端固接,两个驱动链条绕过并驱动各自棘轮棘爪链轮组。本发明解决了由于操作人体型有区别导致的无法采用使用的最佳受力点踩踏骑行的问题。
