An apparatus for the measurement of the energy expenditure at an operating member, which for example is to be attached to the pedal of a bicycle or similar article. This device is particularly precise so that as small as desired flexing movements of an actuating member are transmitted through a control member to a movable control gear, which on its part is coupled with a mechanical counting mechanism measuring and summing the flexing movements. The transmittance can take place either through comb-like control springs of which the tongues are stubbed at the ends and which work together with the rim teeth of the control gear, or there can be included in the control gear a sensitive freewheel which transmits the flexing movements only in one direction.
