ABSTRACT:
A device for controlling the braking power in a brake equipment of a bicycle exerciser is capable of keeping the brake power of this equipment constant or giving it a programmed variation. The device comprises a non-electronic comparing means, which compares the existing power of the equipment (represented by a first r.p.m.), with the desired power of the equipment (represented by a second r.p.m.). If there is a difference between these two r.p.m., the comparing means delivers an output signal in the form of a third r.p.m., which signal is utilized to control a brake setting means for the brake equipment, such that the first and the second r.p.m. are brought into accordance.
