A bicycle pedal (1) comprising a pedal-pin (3) which extends along a longitudinal reference axis (A), and a measuring apparatus (2) provided with a sensor circuit (9) which is adapted to measure the deformation of the pedal-pin (3) caused by the force exerted by the cyclist on the pedal (1) and comprises a first (12) and a second Wheatstone bridge measurement circuit (13), each of which comprises four strain gauges (A1,B1,Cl,D1), (A2,B2,C2,D2). The four strain gauges (A1,B1,Cl,D1) of the first Wheatstone bridge measurement circuit (12) are arranged on a first, outer surface portion (3X) of the pedal-pin (3) which extends approximately parallel to the longitudinal axis (A); the four strain gauges (A2,B2,C2,D2) of the second Wheatstone bridge measurement circuit (13) are arranged on the pedal-pin (3) on a second, outer surface portion (3Y) of the pedal-pin (3) which extends approximately parallel to the longitudinal reference axis (A).
