Abstract

One embodiment of a tricycle (20) having a spine frame (22), supported by a rear wheel (34) and a pair of steerable front wheels (36), and supporting a recumbent seat (42) pivotably attached at its rear. A pedal boom (44) extends forwardly of the spine (26) and supports a pedal crank assembly (46). The front wheels each support a lateral arm (28) with the front wheel pivotably attached at the distal end and an angular projection (80) attached at the proximal end. A pivot (78) connects each angular projection to the spine, allowing the lateral arms and attached front wheels to fold to a stowed position alongside the spine. Another pivot (84) connects the boom to the spine, allowing the boom fold back to a stowed position against the spine. In the travel position, a clamp arrests the angular projections, and can arrest the boom and seat. The tricycle is collapsible to several levels of compactness. Other embodiments are described and shown.
