Equipment Features

Step-Through DesignThe RBK 815 recumbent bike features a step-through design (14 inches; 36 cm wide) with a very low step-over height (4 inches; 10 cm).

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 user's legs. The console is mounted at an optimal viewing angle, with the machine controls within easy reach.

HandlebarsThe console handlebars help with entry and exit, while the riding handle bars provide optional hand and arm positioning and heart rate monitoring.

SeatThe new, 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.

BiomechanicsTo achieve proper pedaling biomechanics, Precor designed the recumbent bike to maintain some of the advantages 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.

BearingsPedal axles and bearings are designed for smooth operation and exceptional service life.

PedalsFor double the convenience, dual-sided pedals allow the rider to use the pedals with or without the integrated pedal strap. The extra-wide pedal comfortably accommodates feet of all sizes to allow proper pedaling form, with the foot directly over the user's knee.

FrameTwo-step powder-coating process applies rust-resistant undercoat and cosmetic topcoat to steel frame.

Seat AdjustmentThe simple seat adjustment allows the user to change the position of the seat with one hand, either on or off the bike.

CoversShrouds are attached with minimal hardware and can be removed without taking off the pedals or cranks.
