The RBK635 recumbent bike features the P31 console and a step-through design to appeal to a wide range of exercisers. The simple seat adjustment allows the user to change the position of the seat with one hand, either on or off the bike. A ventilated air flex seat provides exceptional comfort. This bike is a cost-effective option for a broad range of environments, such as corporate gyms, apartment complexes, and fire departments. The Experience™ Series 600 Line is a professional recumbent stationary bike featured in corporate wellness studios, personal training studios, multi-family complexes, and physical therapy centers that strikes the optimal balance between durability, reliability, and innovation.
The 600 Line of recumbent bikes features simple seat adjustments and a ventilated air flex seat that provides exceptional comfort. The single-sided pedals are integrated with pedal straps that comfortably accommodate feet of all sizes and allow for proper pedaling form. Each bike in this line also features an integrated handheld heart rate that integrates with most 5 MHz HR chest straps. The 600 Line of recumbent bikes features three models: RBK 635, RBK 665, and RBK 685. The difference between each model is the console (P30, P62, or P82) and is available in a Black Pearl frame.

Comfortable Rides
Attention to detail makes all the difference in the world. With a step-through design for easy mounting, and a seat with a flexible suspension system, a ventilated, curved seat back, and easily adjustable on or off the bike, you are assured a cool, comfortable ride.

Geometric Perfection
To reduce pressure on your knees, Precor designed the recumbent bike to maintain similar biomechanics as developed for our upright bike. This is done by setting the angle of the seat rail at an offset from the crank to aid with efficient pedaling and reduce shear force on the knee.

Awesome Rides
When you slip into the seat of a Precor recumbent 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.

An optional personal viewing system brings a 15.6-in wide screen television to the P31.

Biomechanics | To achieve proper pedaling biomechanics, Precor designed the recumbent bike to maintain similar biomechanics as developed for the upright bike. That means setting the angle of the seat rail with an offset from the crank to aid with efficient pedaling and reduce shear force on the knee. The seat rail angle is at 15 degrees with a slight offset from the crank axle. This places the knee directly over the ball of the foot (or pedal spindle) when the pedals are in the 2 and 8 o'clock positions. |
| Frame | Two-step powder-coating process on the steel frame. |
| Seat | The new, compact molded seat back features a "floating" suspension system that allows the seat back to move with the user for unsurpassed comfort. The ergonomic, curved design and ample ventilation further enhance user comfort, and the polypropylene material is virtually indestructible. |
