The invention belongs to the technical field of bicycle speed control systems, and discloses a speed control system and a bicycle. A planet gear of a planet gear set in the speed control system is connected with a multi-stage driven wheel set to form an amplification wheel set, an inner gear ring is fixed to an outer shell, and a multi-stage driving wheel set is rotationally arranged on a transmission shaft; the multi-stage driven wheel set is rotationally arranged on the output shaft, and a first clutch transmission assembly is arranged between the driven shaft and each stage of the multi-stage driving wheel set. The first limiter can drive the first limiting shaft to enable the gear shifting convex part of the first limiting shaft to abut against the first clutch transmission assembly, so that the transmission shaft is in transmission connection with any stage of the driving wheel set; the second limiting stopper can drive the second limiting shaft to enable the gear shifting protruding part of the second limiting shaft to abut against the second clutch transmission assembly so that the output shaft and the amplification wheel set can be in transmission connection or drive the first limiting shaft to enable the gear shifting protruding part of the first limiting shaft to abut against the third clutch transmission assembly so that the output shaft and the sun wheel can be in transmission connection.

    本发明属于自行车变速系统技术领域,公开了一种变速系统和自行车,该变速系统中行星齿轮组的行星轮与多级从动轮组连接形成放大轮组,内齿圈固定于外部壳体,多级主动轮组均可转动设置在传动轴上,多级从动轮组可转动设置在输出轴上,且从动轴和多级主动轮组的每一级之间均设有第一离合传动组件;第一限位器可带动第一限位轴使其换档凸部抵接第一离合传动组件使得传动轴与主动轮组的任意一级之间传动连接,第二限位器可带动第二限位轴使其换档凸部抵接第二离合传动组件使得输出轴与放大轮组之间传动连接或带动第一限位轴使其换档凸部抵接第三离合传动组件使得输出轴与太阳轮之间传动连接。
