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.
