Abstract:
A cycle adapted to travel in an upright position along a support surface, comprising:(a) a rigid frame;(b) a plurality of wheels rotatably journaled with respect to said frame;(c) a suspension tube mounted to said frame for reciprocal movement in an upward direction and a downward direction;(d) a seat assembly disposed on an upper end portion of said suspension tube;(e) a drive assembly disposed on a lower end portion of said suspension tube for common movement with said seat assembly, said drive assembly including a pair of foot supports and operative upon actuation to impart rotary movement to one of said wheels;(f) a steering mechanism coupled to a selected one of said wheels; and(g) a biasing assembly disposed between said frame and said suspension tube and operative to bias said suspension tube into a pre-impact position relative to said frame such that movement of said suspension tube in the downward direction is resisted by said biasing assembly, said biasing assembly operative in response to downward movement of said suspension tube to exert a restorative force to urge said suspension tube in an upward direction toward the pre-impact position, thereby to cushion said seat assembly and said drive assembly relative to impacts occurring during operation of the cycle.
