Abstract
In an exercising apparatus for supporting a bicycle, a pivotally mounted member connects to a rear axle of the bike to constrain movement of the axle about the pivot point of the support member. A support roller, located on the horizontally opposite side of the rear axle as is the pivot point, cooperates with the support member to support the rear wheel. A flywheel and variable load means are connected to the roller to simulate the inertia and variable load experienced during the riding of a real bicycle. Preferably, a front fork support connects to the front fork of a bicycle and has an adjustable feature which can change the elevation of the bicycle frame. The front fork support is inclined and connected to the roller and rear axle support member so that when a rider of a bicycle connected to the apparatus leans toward or shifts his weight toward the front fork support, the front fork support bends and the rear tire of the bicycle pivots toward the roller to maintain frictional contact between the tire and roller.
