The invention provides a driving system of a bicycle. The driving system comprises a fluted disc, a chain, a flywheel and a sensing ratchet wheel set. And the flywheel is synchronously linked with the fluted disc through a chain. The sensing ratchet group is connected to the flywheel. The sensing ratchet wheel set comprises a ratchet wheel seat, a ratchet wheel shell, a bottom cover and a whole vehicle rotating speed sensor. The ratchet shell is rotatably arranged on the ratchet seat. The bottom cover is rotatably arranged at the end part of the ratchet wheel seat; and the whole vehicle rotating speed sensor is arranged between the ratchet wheel seat and the bottom cover. The whole vehicle rotating speed sensor is used for sensing the rotating speed of the ratchet wheel seat relative to the bottom cover. If the tooth ratio of the flywheel to the fluted disc is adjusted to be between 1 and 0.5, the number of pulse signals output by the whole vehicle rotating speed sensor is between 24 and 150 every time the fluted disc rotates by one circle.
本发明提供一种自行车之驱动系统,包含齿盘、链条、飞轮以及感测棘轮组。飞轮通过链条与齿盘同步连动。感测棘轮组连接于飞轮。感测棘轮组包含棘轮座、棘轮壳、底盖以及整车转速感测器。棘轮壳可转动地设置于棘轮座上。底盖可转动地设置于棘轮座的端部。整车转速感测器设置于棘轮座与底盖之间。整车转速感测器用以感测棘轮座相对底盖的转速。若飞轮与齿盘的齿比被调整至1与0.5之间,每当齿盘转动一圈时,整车转速感测器输出的脉冲讯号数量介于24与150之间。
