Abstract
A stationary exercise cycle is disclosed having a drive wheel which receives both user driving force and automatically controlled friction brake resistance, i.e., it is a single-stage device. Free-wheeling is provided between a user-driven shaft and the periphery of the drive wheel, which is braked by a friction belt. Automatic resistance control is provided by an electronic system, which receives actual load information from a load cell, and RPM information from a speed sensor. The friction belt is tightened or loosened by a motor-driven pulley, in response to signals indicating an "error" between load command and actual load. The load information is accurately obtained by a pivoted member to which both ends of the friction belt are attached.
