ABSTRACT:
A wheeled vehicle is arranged to be completely hand powered and controlled. Since primary utility is for paraplegics, the vehicle is preferably configured as a tricycle using wheels specifically dimensioned as for use with bicycles. A column is pivoted around the front of the main frame of the vehicle with a front wheel attached at one end and a hand crank assembly attached at the other end in a manually accessible position relative to the vehicle seat. The crank assembly is coupled to drive the front wheel and includes rotatable sleeves on the grip with control mechanisms attached to these rotatable sleeves. By including brake actuating levers on the sleeve, the vehicle can be motivated, braked and/or steered by hand. Shifting mechanisms for speed control can be included either in proximity to the seat on the main frame or on the grip sleeves through suitable adaptations. A mechanism can be included to permit repositioning the grip cranks into any of a plurality of relative radial orientations.
