The UBK 615 Upright Bike is from the commercial range of Precor upright bikes with 12 programs, 25 resistance levels, touch and telemetry heart rate monitoring with SmartRate feature. The seat and pedals can be replaced with your own for a custom feel and ride. The 835 also features 3-position handlebars for upright, cruising and road positions, dual-sided pedals and K.O.P.S. biomechanics. Handlebars - Handlebar design offers three riding positions - upright, cruising, and road. The overall width of the handlebars places the user in a better ergonomic position with the forearms more directly under the shoulders. In the road position, the ergonomic-shaped handlebars position the wrists in a natural, neutral position. Seat - Ergonomic seat design with comfort groove. 10.5 inches (27 cm) width that quickly tapers to a narrow nose for improved riding comfort. Universal seat post allows easy installation of your own saddle. Biomechanics - KOPS Biomechanics (Knee Over Pedal Spindle) - to achieve proper pedalling biomechanics, the seat post and seat post offset from the crank is key to aide in efficient pedalling and reduced shear force on the knee. The seat post angle is 74 degrees with a 5 inch (13 cm) offset from the crank axle. This places the forward knee directly over the ball of the foot (or pedal spindle) when the pedals are in a horizontal position.
