SKU: PCUBK635-1 Inquire

The UBK 635 upright bike features custom-designed handlebars with integrated handheld heart rate for maximum comfort and efficient workout experience. Easy seat adjustment, redesigned saddle for riding comfort, and improved knee over pedal spindle (KOPS) geometry for efficient pedaling mean a smooth, comfortable workout. This bike is a cost effective option for a broad range of environments such as corporate gyms, apartment complexes, and fire departments.


  • Commercial-Proven Design

    The easy to remove shroud ensures easy access to the belt-drive system for maintenance and servicing without removing the
    pedals or crank.

  • Innovation for Superior Riding Comfort

    Over-molded handle bars add comfort and durability while offering heart rate contacts and three ergonomic riding positions: upright, cruising and road. The familiar pop-pin seat adjustment similar to other commercial bikes allows the user to easily change the seat to their desired height.

  • P30 Console

    Created to complement the entire Experience Series™, the P30 console features easy-to-use motion controls and an LED-based console that focuses on the essential fitness stats that keep users informed and engaged.

Equipment Features

  • Covers

    Covers are attached with minimal hardware and can be removed without taking off the pedals or cranks.

  • Cable Management


  • Accessories Holder(s)


  • Transport Wheels


  • Frame

    Two-step powder-coating process on steel frame.

  • Bearings

    Pedal axles and bearings are designed for smooth operation and exceptional service life.

  • Seat

    Familiar pop-pin seat adjustment allows the exerciser to easily change the seat to their desired height.Improved, ergonomic saddle design with comfort groove is injection-molded polyurethane with custom density for optimum riding comfort. 10.5 inches (27 cm) width quickly tapers to a narrow nose for improved riding comfort.

  • Handlebars

    Over-molded handlebar design offers the exerciser three comfortable riding positions: upright, cruising, and road. In the road position, the ergonomic-shaped handlebars position the wrists in a natural, neutral position. The optimum width of the handlebars provides stability and comfort along the entire forearm. The overall width of the handlebars is similar to indoor cycling bikes, which is narrower than most stationary bikes. This places the exerciser in better ergonomic position, with the forearms more directly under the shoulders. In the cruising position, the handlebar is more comfortable on the exerciser’s hands. Touch heart rate is integrated in the upright position.

  • Pedals

    Over-sized, single-sided pedals with integrated pedal strap comfortably accommodates feet of all sizes, which allows proper pedaling form. The weighted pedals allow for easy placement of foot on the pedal.

  • Biomechanics

    To achieve proper pedaling biomechanics, the seat post angle and seat post offset from the crank are key to 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.
