Abstract

See full text

A cycle with a mechanical advantage drive and leaning steering system comprises a frame with at least one wheel rotationally attached to the frame. A drive rim is attached to the wheel adjacent to the outer circumference of the wheel. A pulley is rotationally attached to the frame. A belt is trained around and engages both the pulley and the drive rim. Because the belt is positioned at the outer circumference of the wheel a mechanical advantage is created that significantly reduces the amount of force required on the belt to propel the cycle. The cycle may be steered via the rotation of the rider's body on a seat. This rotation translates to rotation of a front portion of the frame with respect to the a rear portion of the frame about a pivoting interface portion, thereby causing the cycle to turn.
