Claim:
1. An apparatus for measuring and determining the force, the torque and the power on the pedal shaft of a bicycle, wherein the pedal shaft extends along a pedal shaft axis, comprising: at least one pedal having a pedal body; a deformation body contained within the pedal body, wherein the deformation body is stationarily connected to the pedal body at a first location and is rotatably supported by the pedal shaft at a second location spaced from the first location, wherein the deformation body includes a cantilevered section that extends between the first and second locations and wherein the deformation body connects the deformation body to the pedal body at the second location, wherein pedaling forces applied to the pedal body by a user are transferred from the pedal body through the cantilevered section of the deformation body to the pedal shaft; an angle sensor associated with the deformation body, wherein the angle sensor measures an angle of orientation of the deformation body relative to the pedal axis; and a strain sensing arrangement on the cantilevered section of the deformation body for measuring strain experienced by the cantilevered section of the deformation body due to forces applied to the pedal.
