Abstract
One embodiment of a tricycle having a spine frame, supported by a rear wheel and a pair of steerable front wheels, and supporting a recumbent seat pivotably attached at its rear. A pedal boom extends forwardly of the spine and supports a pedal crank assembly. The front wheels each support a lateral arm with the front wheel pivotably attached at the distal end and an angular projection attached at the proximal end. A pivot 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 connects the boom to the spine, allowing the boom to 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.
