Step-Through Design:The RBK 615 recumbent bike feature 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 user's
legs. The console is mounted at an optimal viewing angle, with the machine
controls within easy reach.
Handlebars:The console handlebars help with entry
and exit, while the riding handle bars provide optional hand and arm
positioning and heart rate monitoring.
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.
Biomechanics:To 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.
Bearings:Pedal axles and bearings are
designed for smooth operation and exceptional service life.
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.
Frame:Two-step powder-coating process applies
rust-resistant undercoat and cosmetic topcoat to steel frame.
Seat Adjustment:The simple seat adjustment allows
the user to change the position of the seat with one hand, either on or off the
