  • Patent number: 5544906
    Abstract: An improved human powered recumbent vehicle is provided. The vehicle includes a frame that comprises a central keel. The keel comprises four tubes that are spaced equidistant from a central longitudinal axis. Outrigger arms are disposed approximately halfway along the longitudinal axis of the keel and extend forwardly and outwardly therefrom. The angle that each outrigger arm forms with the keel, provides an access area that allows a rider access to the seat without having to step over any portion of the invented vehicle, for easy mounting and dismounting. Outboard ends of the arms terminate in pivotable connectors that may be provided for wheel bearing yokes. A rear section of the keel is wide enough to accommodate a wheel. The keel has a prow that terminates in a single plane, so that the vehicle can be placed on its prow for storage in an upright position, to minimize storage space.
