A bicycle having a frame geometry, elliptical pedaling system, and seat design and configuration which, in combination, moves the rider's body weight rearward relative to its location in conventional bicycle designs, increases the hip joint range of motion and maximum knee flex experienced during pedaling, increases the distance over which the rider's knee is directly over the pedal spindle during pedaling, provides a seating platform from which to brace and push during leg extension, and thereby increases overall efficiency and rider comfort.
