The invention discloses a one-step five-step variable-speed bicycle which comprises a bicycle frame. The faucet is fixedly mounted on one side of the frame; the front wheel frame is fixedly mounted on one side of the frame and is positioned below the handlebar; the front wheel rim is fixedly mounted in the front wheel frame; the rear wheel carrier is fixedly mounted on one side, far away from the front wheel carrier, of the frame; according to the bicycle, under the cooperation of the multiple wheel discs and the chain shaft disc, speed change of the bicycle can be achieved, transmission can be achieved in the mode that a single pedal is treaded, namely treading is conducted with one foot, meanwhile, the bicycle speed can be controlled according to the treading depth, and the bicycle is more convenient to use. Therefore, the speed changing structure is simple, complex chain and speed changer combination is not needed, the installation difficulty and the later maintenance cost are reduced, meanwhile, more labor is saved due to the single-pedal treading mode, and the whole speed changing device is more convenient to operate.

    本发明公开了单踏五步变速自行车,包括:车架;龙头,龙头固定安装在所述车架的一侧;前轮架,前轮架固定安装在所述车架的一侧位于龙头的下方;前轮圈,前轮圈固定安装在所述前轮架的内部;后轮架,后轮架固定安装在所述车架远离前轮架的一侧;后轮圈,后轮圈固定安装在所述后轮架的内部,本发明可以在多个轮盘和链轴盘之间的配合下,进而实现自行车的变速,且可以通过踩踏单踏板,即一只脚进行踩踏的方式,进而传动,同时可以根据踩踏的深浅进行控制车速,进而使得变速的结构简单,无需复杂的链条和变速器组合,降低安装难度和后期的维护成本,同时单踏板的踩踏模式更加省力,使得整体更便于操作。
