The Precor UBK 835 upright bike is one of Precor’s commercial upright bikes with 12 programs, 25 resistance levels, touch and telemetry heart rate monitoring with SmartRate. 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 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 pedaling biomechanics, the seat post and seat post offset from the crank is key to aide in efficient pedaling 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.
Bearings The bottom bracket assembly uses a hardened steel shaft with deep-groove sealed precision ball bearings designed for smooth operation and exceptional service life.
Pedals Dual-sided pedals can be used without the pedal straps. The extra wide pedal comfortably accommodates feet of all sizes.
Frame Two-step powder-coating process applies rust-resistant undercoat and cosmetic topcoat to steel frame.
Seat Adjustment New, convenient seat adjustment allows the user to easily change the seat to their desired height, either on or off the bike.
Covers Covers are attached with minimal hardware and can be removed without taking off the pedals or cranks.
