Product Description
The Precor UBK 835 upright bike is the same commercial bike found in fitness centers and five-star resorts worldwide, with finely tuned ergonomics and a 750-watt two-stage drive system that keeps every pedal stroke smooth and consistent at any resistance level. It’s self-powered, so it can be placed anywhere on the floor without a dedicated outlet, and it’s available in Black Pearl or Storm Grey frames.
Over-molded handlebars offer three ergonomic riding positions — upright, cruising, and road — with integrated touch heart-rate contacts in easy reach. The seat-rail angle and crank-axle offset are engineered to keep your knee aligned over the pedal spindle, reducing joint stress while promoting an efficient pedal stroke.
Innovation for Superior Riding Comfort
Durable over-molded handlebars add comfort across all three riding positions, and the simple one-hand seat adjustment lets users change seat position on or off the bike.
P31 Console
An LED console that works harder for you, your servicers, and your exercisers: integrated asset management puts service information at technicians’ fingertips, while well-placed channel and volume controls keep workouts simple.
Equipment Features
| 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. |
| Transport Wheels | Integrated |
| Cable Management | Optional |
| Universal Seat Mount | Yes |
Resistance System
| 3-Piece Crank | 3-piece compact crank assembly tightens positively, reducing the need for periodic adjustments. The 170 mm crank arm accepts any standard road or mountain bike pedal. |
| Drive System | The two-stage drive system yields a smooth, comfortable, quiet operation with a lower start-up resistance and more consistent resistance progression than single-stage drive systems. |
| 3-Phase Generator | 3-phase generator / eddy current resistance system requires no backup battery in order to efficiently power the bike. |
| Belt Drive | Belt drive for smoother, quieter operation and reduced maintenance. |
