The invention discloses a body-building stepping bicycle. The body-building stepping bicycle mainly structurally comprises a front wheel connected to a steering device on a frame and a group of rear wheels for connecting a rear wheel shaft to a bottom plate, the height of the steering device can be controlled through a height control switch; two groups of gear transmission systems are arranged on the rear wheel shaft and are connected with the corresponding pedals through connecting rods; the gear transmission system consists of a first gear transmission system and a second gear transmission system; a first rack is provided with double racks which are respectively meshed with a main gear and a first pinion; the second gear transmission system is composed of a second rack connected through a main gear, a second large gear, a second pinion and a second driving wheel meshed with the second large gear, wherein the second large gear and the second pinion are coaxial. The second rack is connected with a third connecting rod through a hinge; the driving wheel is provided with a timely driving mechanism, so that the rear wheel shaft can move unidirectionally; and two ends of shafts of the main gear, the first pinion and the second pinion are respectively fixed on the frame and the bottom plate through bearings.

    本发明公开了一种健身踏步自行车,主要结构部分包括连接在车架上的转向装置上的前轮以及将后轮轴连接在底板上的一组后轮;转向装置的高度可以通过高度控制开关来控制;后轮轴上设置有两组齿轮传动系统通过连杆与相应的脚踏板连接在一起;齿轮传动系统由第一齿轮传动系统和第二齿轮传动系统组成:第一齿条上设置有双齿条,分别与主齿轮以及第一小齿轮相啮合;第二齿轮传动系统由通过主齿轮连接的第二齿条和同轴的第二大齿轮和第二小齿轮以及和第二大齿轮啮合的第二驱动轮组成;第二齿条通过铰链和第三连杆相连;驱动轮设置有适时驱动机构,使后轮轴可以单向运动;主齿轮、第一小齿轮和第二小齿轮的轴两端均通过轴承分别固定在车架和底板上。
