A bicycle pedal, having a pedal shaft which has an end surface in which a blind hole is formed, is provided with a permanent magnet which is designed to interact with a sensor of the pedalling cadence, provided on the frame of the bicycle. The permanent magnet is housed within the blind hole and retained simply by magnetic attraction, if the pedal shaft is made from ferromagnetic material, or, for example, if the pedal shaft is not made from ferromagnetic material, by means of an auxiliary element of ferromagnetic material which is fixed within the aforesaid blind hole and to which the permanent magnet adheres simply by magnetic attraction.
