摘要
The invention relates to an apparatus for measuring and determining the force, the torque and the power on a crank, in particular the pedal crank of a bicycle, comprising an evaluation device, in particular a bicycle computer, and at least one pedal, wherein the force and angular speed variables are converted into electrical signals and supplied to the evaluation device, the pedal comprises a pedal body, a deformation element, a pedal shaft and an angle transmitter, and wherein the force variable is determined by measuring the deformation of the deformation element using strain gauges, preferably by measuring the individual normal strains of the strain gauges, and wherein four pairs of strain gauges assigned to each other are arranged at different angles, preferably +/- 45, with respect to the pedal shaft.
