Claim:
A collapsible tricycle comprising: a spine frame having a spine supported by a rear wheel and by a pair of steerable front wheels, a pedal boom extending forwardly of the spine and supporting a pedal crank assembly, a drive system connecting the pedal crank assembly with the rear wheel, and a seat supported by the spine; a lateral arm supporting each of the front wheels, each lateral arm having a proximal end and a distal end with the front wheel pivotably attached at the distal end and an angular projection attached at the proximal end; a pivot connecting each angular projection to the spine and allowing each lateral arm to fold from a travel position, with the distal end spaced from the spine, to a stowed position alongside the spine; and clamping means on the spine to arrest the angular projections in the travel position in a position along the spine and to release the angular projections to a position pivoted away from the spine to allow folding of the lateral arms to their stowed position.
