According to the pedaling frequency sensor and the bicycle power assisting system, the pedaling frequency of a user on a bicycle can be determined only by enabling a chain wheel or a chain wheel to slightly rotate by the user, so that power assisting on the bicycle is started in time, and power assisting time delay can be reduced. The pedaling frequency sensor provided by the embodiment of the invention comprises a main body, a light emitter and a light receiver, wherein the main body is provided with two bulges and a recess located between the two bulges, the light emitter is fixed on one bulge, namely, fixed on one side of the recess, the light receiver is fixed on the other bulge, namely, fixed on the other side of the recess, and the light emitter and the light receiver are arranged oppositely. In the recess of the main body, a chain or a sprocket of the bicycle can pass between the light emitter and the light receiver, and a gap between rollers of the chain or a gap between teeth of the sprocket faces towards the light emitter, namely towards the light receiver.
本申请公开了一种踏频传感器以及自行车助力系统,仅需用户令链轮或链轮轻微转动,即可确定用户对自行车的踏频,从而及时启动对自行车的助力,可减少助力延时。本申请实施例提供的踏频传感器包括:主体,光发射器以及光接收器。其中,主体具有两个凸起以及位于两个凸起之间的凹陷,光发射器固定于其中一个凸起,即固定于凹陷的一侧,光接收器固定于另一凸起,即固定于凹陷的另一侧,可见,光发射器和光接收器是相对设置的。在主体的凹陷中,自行车的链条或链轮可在光发射器以及光接收器之间穿过,且链条的滚子之间的空隙或链轮的齿之间的空隙朝向光发射器,也就相当于朝向光接收器。
