Precor RBK 665 Recumbent Bike
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. 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.
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.
