ABSTRACT:
In a bicycle-type exercising apparatus, a roller is driven by the rear wheel of the bicycle. The roller is connected to a load device which varies the load resistance experienced by the person exercising on the exercise apparatus. The load device comprises a differential band brake having a pivoted member with the opposite ends connected to opposing ends of a brake band. A spring is inserted between one end of the pivoted member and the corresponding end of the brake band. A self-correcting servomotor is connected to the pivoted member to control the braking force. A computer may be programmed to control the motion of the servomotor, and thus control the forces exerted by the load device.
