A bicycle component comprising a stress/strain sensor aligned according to a stress/strain to be detected, and a temperature sensor associated with said stress/strain sensor, wherein said stress/strain sensor and said temperature sensor lie in planes that do not coincide with one another and are not parallel to each another.

A bicycle speed sensor is provided on a bicycle. The bicycle includes a chain stay, a rear wheel, a brake disk and a positioning member. The rear wheel includes a hub and the brake disk includes a center hole disposed for the hub to pass through. The positioning member passes through the chain stay, the center hole and the hub so that the rear wheel and the brake disk are positioned on the chain stay. The bicycle speed sensor includes a signal transmitter and a signal sensor. The signal transmitter is configured to transmit a signal and disposed on the brake disk. The signal sensor receives the signal from the signal transmitter and is disposed on the chain stay. By fixedly positioning the signal transmitter and the signal sensor at the brake disk and a default position of and the chain stay respectively, displacements of sensor components is prevented to provide reliable sensing data.
