Patent ID: 7077789

Claim:
A stationary exercise apparatus comprising: an upright bicycle frame; a flywheel mounted on a shaft extending through a center of the flywheel; a magnetic resistance device having a fan-shaped adjustment board, a magnet unit, a wire connection member connected to the adjustment board, a curved slot and a pivot hole wherein the slot and hole are separately defined through the adjustment board; a connection board connected to the adjustment board; and a resilient member connected between the connection board and the adjustment board that biases the boards toward each other wherein the shaft also extends through the curved slot and a first hole in the connection board, an axle extends through the pivot hole and a second hole in the connection board and the axle and the shaft are disposed a distance from each other in parallel on two support plates which are connected to two upright posts of the bicycle frame such that a user can increase or decrease rotational resistance on the flywheel by adjustably pivoting the magnetic resistance device toward and away from a peripheral edge of the flywheel by manipulating the wire connection member to over come the bias of the resilient member.
