The Experience™ Series 600 Line are professional recumbent stationary bikes 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 feature 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. 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 either a black or silver frame.

Equipment Features
Covers | Covers are attached with minimal hardware and can be removed without taking off the pedals or cranks. |
Cable Management | Optional |
Accessories Holder(s) | Yes |
Transport Wheels | Integrated |
Biomechanics | To achieve proper pedaling biomechanics, Precor designed the recumbent bike to maintain similar biomachines 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 reduced 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 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. |
Bearings | Pedal axles and bearings are designed for smooth operation and exceptional service life. |
Seat Adjustment | The simple seat adjustment allows the exerciser to change the position of the seat with one hand, either on or off the bike. |
Handlebars | The console handlebars help with entry and exit, while the riding handle bars provide optional hand and arm positioning and heart rate monitoring. |
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. |
Step-Through Design | The RBK 685 recumbent bike features a step-through design with a very low step-over height. |
Ergonomics | The riding cockpit is designed with sound ergonomics. The seat pads are angled for optimal comfort, maximum low-back support, and minimal interference with the movement of the exerciser’s legs. The console is mounted at an optimal viewing angle, with the machine controls within easy reach. |
