A human-powered vehicle may include a frame and a drive member pivotally coupled to the frame. Pivotal reciprocal motion of the drive member in either direction may generate rotational motion to the wheels of the human-powered vehicle. The seat of the human-powered vehicle may be positioned such that an axis about which the drive member pivots is located below, or closer to the ground surface, than the seat.

A motion transfer apparatus comprising a frame; at least one wheel shaft operably coupled to at least one wheel, the at least one wheel shaft rotatable on the frame; a gear assembly coupled to the at least one wheel shaft; at least one pedal engaging the gear assembly and movable by an appendage within a predetermined angular range to apply a force; at least one crank arm with a predetermined length coupled to the at least one pedal and to the gear assembly for applying the force directly from the pedal to the gear assembly to rotate the at least one wheel; and a restorative member generating a restorative force to return the pedal and the at least one crank arm from a lower stroke position to an upper stroke position.

Hand pedals for turning the crank set of an arm driven tricycle have modular interchangeable components including a bearing which mounts on the spindle of the crank. A bridge connects the bearing to a handle. The bridge has two legs connected by a transverse spar. Different bridges and handles may be used having different sizes, shapes, lengths and angular orientations which allow the hand pedals to be customized to accommodate a particular user. Hand pedals may also be used on hand cranked bicycles, stationary hand cranked bicycles and industrial equipment.

A hand-powered vehicle is provided for transportation and entertainment purposes. The vehicle has a frame supporting a pair of side wheels that are driven by the user. The frame includes a front portion and a pair of side portions extending rearwardly to the side wheels. The side portions of the frame do not extend rearwardly past the side wheels. The user sits on a seat that is supported by a portion of the frame extending rearwardly from the front portion and between the two side wheels. A third wheel is provided under or behind the seat, and that wheel is preferably a caster that is coupled to the frame at an angle to a vertical axis. The side wheels have hand grips extending therefrom, and the hand-powered vehicle is configured to be propelled by a user applying a force through the hand grips to rotate the side wheels.

A collapsible tricycle having linkage to all three wheels enabling a smaller turning radius when all three wheels are tilted during a turn. The tricycle folds through the rear frame having a hinged rear axle with linkage to pivotal handle bars mounted to the rear frame that when pivoted from their storage position to their operative position also pivots the rear axle through said linkage from its stored position under the rear frame into its operative position. The rear axle is segmented so that when moved to its stored position under the rear frame each of the rear wheels can be pivotally collapsed against the frame.
