Field: Transport (Mechanical engineering)
Classification: CPC B  G | IPC B  G

Claim 0:
1. A pedal for bicycles comprising:
a pedal-pin which extends along a longitudinal reference axis and has a first axial end structured to be coupled to a crank of a bicycle,
a pedal-body coupled in a freely rotatable manner on said pedal-pin so that said pedal-body can rotate around said reference axis,
at least one internal chamber which is made in said pedal-pin and has an internal surface that extends along said reference axis approximately coaxial to the pedal-pin,
an electronic power measurement system comprising:
strain gauges having a thin laminar structure, which are coupled to said pedal-pin and are configured so as to provide electrical measurement signals indicative of the mechanical deformation of the pedal-pin,
an electronic processing circuit which is electrically connected to the strain gauges and is configured so as to determine, on the basis of these electrical signals, the mechanical deformation of the pedal-pin caused by the force exerted by the cyclist during pedalling on the pedal-pin via the pedal-body,
said pedal being characterised in that:
the strain gauges are rigidly fixed on the internal surface of said internal chamber by a fixing layer of adhesive based material, so that said strain gauges are supported by the internal surface in said internal chamber,
said strain gauges are exclusively supported by said internal surface of said internal chamber.
