Abstract
A cycle adapted to travel in an upright position along a support surface comprises a rigid frame, a plurality of wheels rotatably journaled with respect to the frame, a suspension tube mounted to the frame for reciprocal movement in upward and downward directions, a seat assembly disposed on an upper end portion of the suspension tube, a drive assembly disposed on a lower end portion of the suspension tube for common movement with the seat assembly, a steering mechanism, and a biasing assembly disposed between the frame and the suspension tube. The biasing assembly is operative to bias the suspension tube into a pre-impact position relative to the frame such that movement of the suspension tube in the downward direction is resisted by the biasing assembly through exertion of a restorative force which urges the suspension in a upward direction toward the pre-impact position, thereby cushioning the seat assembly and the drive assembly relative to impacts occurring during operation of the cycle.
