ABSTRACT:
A conventional bicycle is mounted and restrained for exercise and/or rider training with safety. When released, the bicycle can be used in a normal manner. A moving roller supported beltway for the front wheel only of the bicycle closely simulates a true roadway surface and may be powered by the rear traction wheel of the bicycle or by an independent drive device. A flexible lateral restraining system for the bicycle limits its lateral tilting within safe limits, and in cooperation with side longitudinal guide elements for the bicycle wheels, close to the edges and level of the beltway, prevents a rider from deviating from the boundaries of the beltway. A frame of the restraining means can serve as a hand support for walkers or joggers utilizing the beltway.
