The invention belongs to the technical field of bicycles, and discloses a transmission mechanism for a bicycle and the bicycle. The transmission mechanism for the bicycle comprises a rotating assembly and two transmission assemblies, the rotating assembly comprises a rotating shaft and a rotating sleeve, the outer wall of the rotating sleeve is configured to be fixedly connected with spokes of a wheel, and the rotating shaft is sleeved with the rotating sleeve and rotationally connected with the rotating shaft; a plurality of tooth grooves are concavely formed in the inner wall of the rotating sleeve at equal intervals in the circumferential direction, at least one convex tooth is arranged on the outer wall of the rotating shaft, and each convex tooth can selectively abut against one tooth groove; the two transmission assemblies are arranged on the two sides of the rotating shaft correspondingly. Each transmission assembly comprises a pedal assembly and a reset assembly, and the pedal assembly is configured to be rotationally connected with the frame and fixedly connected with the rotating shaft; the reset assembly is fixed to the frame and fixedly connected with the rotating shaft. Through cooperation of the convex teeth and the tooth grooves, rotation of the wheel is achieved, the maintenance cost is low, generated vibration and noise are small, the wheel is driven to rotate by treading and loosening the pedal assembly, and a user has good riding experience.

    本发明属于单车技术领域,公开一种单车用传动机构及单车。单车用传动机构包括转动组件和两组传动组件,转动组件包括转轴和转套,转套的外壁被配置为与车轮的辐条固定连接,转套套设于转轴外且与转轴转动连接;转套的内壁沿周向等间距凹设有多个齿槽,转轴的外壁设有至少一个凸齿,每个凸齿能选择性地与其中一个齿槽抵接;两组传动组件分别设置在转轴的两侧;每组传动组件包括脚踏组件和复位组件,脚踏组件被配置为与车架转动连接,且与转轴固定连接;复位组件固定于车架,且与转轴固定连接。通过凸齿与齿槽的配合,实现对车轮的转动,维护成本较低,产生振动和噪音较少,并且通过踩压和松开脚踏组件带动车轮转动,使使用者有良好的骑行体验。
