The invention relates to a chainless coaxial transmission bicycle. The chainless coaxial transmission bicycle comprises a frame used for supporting three wheels, a saddle and a handlebar. The three wheels fall into a large wheel and two small wheels, the large wheel is arranged in the middle of the bicycle body and is a driving wheel, the front small wheel is a direction wheel, and the rear smallwheel is a supporting wheel; the saddle is arranged between the supporting wheel and the large wheel; a shaft of the large wheel is also a pedal shaft and is not driven by a chain; the relative positions of the saddle and the pedal shaft are the same as those of a traditional bicycle, and the riding habit of a rider is not changed. The chainless coaxial transmission bicycle provided by the invention has the characteristics of three wheels, no chain, coaxality of the pedal shaft and the large wheel, and a bicycle body 350mm shorter than a traditional 28-type bicycle. The whole bicycle is simplein structure, short in bicycle body and free of the trouble of chain falling.

    本发明项目是一种无链条同轴传动自行车,包括车架,用于支撑三个车轮,一个车座和一个车把;三个车轮分为一个大车轮和两个小车轮,大车轮在车体的中间,为驱动轮,前面的一个小车轮为方向轮,后面的一个小车轮为支撑轮;车座在支撑轮与大车轮之间;大车轮的轴也是脚蹬轴,没有链条传动;车座与脚蹬轴的相对位置与传统的自行车一样,没有改变骑行者的骑行习惯。本发明是一种无链条同轴传动自行车,其特征是三个车轮、没有链条、脚蹬轴与大车轮的轴同轴、车身比传统28型自行车短350mm。整车结构简单,车身短,没有掉链子的烦恼。
