ABSTRACT:
An exerciser for simulating bicycling having a collapsible bicycle stand, provided with a flywheel for the storage of energy, rotatably supports an elevated flywheel spindle behind a rear, treadle-powered bicycle wheel such as to be driven through frictional engagement with the rear wheel tire only while a rider is seated on the bicycle. The rear wheel is held in a raised position by the stand such as to fully support the weight of the rider, causing the rear wheel to be freely rotatable, impeded essentially only by the inertia of the flywheel. The stand accomodates wheels of various diameters, and a manual control readily accessible to the seated rider permits selection of tire to spindle force no greater than that required to avoid slippage. The tire is also protected against damage by a flywheel brake which becomes effective in the event the bicycle brake is suddenly applied while there is still negative clearance between the flywheel and the spindle, and therefore, while the flywheel is still spinning.
