A stabilizing tracking system for a spinner exercise bicycle includes a spool that is attached to the bike in the loop path of the drive belt between the drive and flywheel sprockets. The spool is located such that the belt is forced to travel below the top dead center of the flywheel sprocket. The spool also has flanges such that the standard poly-V-belt is caused to track within the spool. Forcing the belt below top-dead center of the flywheel sprocket and keeping the belt in tack reduces belt wear, stretching, and the tendency of the belt to wobble or sway as it is driving a flywheel. The spool utilizes inner bearings for smooth rotation of the stability tracking spool. The spool compensates for the differential in the thrust from the top, dead center position of the drive sprocket. The spool picks up the slack in the drive belt that and keeps the belt in a close track. The spool also compensates for slippage during start up of the flywheel and keeps the belt from slipping or wobbling.
