AN EXERCISE BICYCLE USABLE FOR PASSIVE AND ACTIVE EXERCISE

摘要

An exercise bicycle usable for passive or active exercise comprises a frame (2) rotatably supporting pedals (6) which are connected to a first pulley (7) which is connected by means of a toothed belt (8) to a pinion (9) keyed to a flywheel (10). The flywheel (10) is connected by means of a V-belt (12) to a pulley (13) fixed to the rotor of an electric motor (14) which is supported by the frame (2). The rotor of the motor (14) constitutes a supplementary flywheel mass for active exercise and the motor (14) can be energised for passive exercise.
