ABSTRACT:
A user powered vehicle which can be propelled upon an ice surface by applying force in repetitive power stroke movements in a rowing manner. The vehicle includes a main framework (10), a forward facing seat (64), a plurality of attached ice runners (14, 16) adapted to support the vehicle for efficient forward movement upon the operating surface, a movable propulsion wheel assembly (18) including at least one propulsion wheel (38) adapted to provide forward thrust when engaged with the operating surface, a rowing assembly (74) and footrest assembly (66) operable for converting rowing motions into propulsion force, and means (86) for transfer of weight from ice runners to propulsion wheel for increased traction during rowing power strokes and for re-transfer of weight to ice runners for improved efficiency between power strokes. The vehicle is adaptable for use on snow or land by replacing ice runners with skis or wheels respectively.
