ABSTRACT:
A resistance freewheel mechanism useful with bicycle type exercisers in which a crank operated drive shaft is positively interlocked with an inertially weighted flywheel by a first positive acting clutch system for rotatably driving the flywheel in one direction and is selectively releasable from the wheel to permit full or partial freewheeling of the latter upon the application of sufficient torsional resistance to release the first clutch system and fully or partially disengage a second clutch system which frictionally couples the drive shaft to the flywheel.
