Precor UBK 600 Line Upright Bike 635/685

GO THE DISTANCE To help ensure a smooth and comfortable workout, the UBK 600 Upright Bike has an easy seat adjustment, saddle designed for riding comfort, and knee over pedal spindle (KOPS) geometry. ERGONOMIC DETAILS COMFORTABLE RIDES A heavily padded seat with the grooves and curves in all the right places and a solid one-piece handlebar that allows you to easily adjust your riding position ensures your stationary bike is not masquerading as a torture device. GEOMETRIC PERFECTION CLEAN RIDES As you already know, the key to a good bike ride is good biomechanics. We set the angle of the seat rail and offset the crank axle to create efficient pedaling that keeps your knee over the pedal spindle and reduces shear force.  AWESOME ENGINEERING AWESOME RIDES When you slip into the seat of a Precor upright bike and start pedaling, you can immediately feel the difference of using a professional-grade machine. We put all our design expertise into ensuring a quiet, challenging, comfortable ride on a solid piece of equipment.
