Abstract
The present disclosure is for a bicycle pedaling frequency sensor comprising a signal acquisition unit, a data transmission unit, and/or a data conversion unit. Pedaling frequency is obtained by recording and converting periodical changes of acceleration and/or of angular velocity in real time. This can be achieved by further incorporating a two axis, a three axis acceleration sensors, and/or gyroscope sensors. The pedaling frequency sensor communicates wirelessly with a computing terminal. It is powered and housed within the cavity of a shell, wherein the shell's outer surface is in thread fit with an inner surface of an expansion component. The expansion component allows the sensor to be inserted into and secured within hollow spaces on a bicycle's pedals and/or cranks.
