BiomechanicsTo achieve proper pedalling 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 pedalling 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.
FrameTwo-step powder-coating process on steel frame.
SeatThe new compact moulded 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.
BearingsPedal axles and bearings are designed for smooth operation and exceptional service life.
Seat AdjustmentThe simple seat adjustment allows the exerciser to change the position of the seat with one hand, either on or off the bike.
HandlebarsThe console handlebars help with entry and exit, while the riding handlebars provide optional hand and arm positioning and heart rate monitoring.
PedalsOver-sized, single-sided pedals with integrated pedal strap comfortably accommodate feet of all sizes, which allows proper pedalling form. The weighted pedals allow for easy placement of foot on the pedal.
Step-through DesignThe RBK 635 recumbent bike features a step-through design with a very low step-over height.
ErgonomicsThe 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.
