Keiser Upright Bike - Rear Wheel Drive Bike 5421.15

Keiser’s Upright Rear Wheel Drive Bike 5421.15 is the first of its kind. The innovative design removes the entire friction system out of the sweat zone, keeping tension consistent and unaffected by moisture. This also protects the flywheel from oxidation and corrosion. The torsion flex frame provides a road like feel, and the new wider spring loaded saddle is designed to reduce soreness. A comfortable saddle, easier chain tension adjustments, and ‘hot’ programs make the Keiser Rear Wheel Drive Bike a trouble-free ride. This bike is also available in a free-wheel version.
