The invention discloses a bicycle treading frequency sensor, comprising a signal acquisition unit arranged on a circuit board and used for acquiring motion acceleration changes or/and angular velocity changes in different rotation directions of a middle axle in real time, a data transmission unit for transmitting the acquired data to a terminal, and a power supply for supplying power to each unit to work. When in use, the treading frequency sensor is fixed on the hollow middle axle of a bicycle, and the middle axle, a crank and pedals of the bicycle rotate synchronously; during riding motion, acceleration change or/and angular velocity change data is acquired in real time and transmitted to the corresponding processing terminal via the data transmission unit for processing, real-time rotating frequency of the middle axle of the bicycle is obtained, and then treading frequency data during riding is acquired. Because the treading frequency sensor skillfully implements counting through periodical changes of acceleration or/and angular velocity data and other data when the bicycle moves and does not need to carry out counting in a sensing mode through periodical relative motion between two separated components, the treading frequency sensor is simple in structure, small in size and works stably and reliably.
