A three-wheeled vehicle having a front body member carrying the front wheel and seat, pivotally connected to a rear body member carrying the rear wheels and handlebar. The pivotal connection is designed to pivot the front body member around a pivotal axis that is projected upwardly and rearwardly at a location rearward of the front wheel whereby pivoting produces sideward and rearward tilting of the front wheel and opposite turning of the rear wheels. Steering is achieved by such pivoting of the front body member which in turn is achieved by a sideward swinging of the seat that is positioned between the two pivotal connections. The rear wheels are preferably canted to provide increased stability for the vehicle as it is maneuvered through a turn.

A tri-supported vehicle comprising; a first body member including a single steerable support member for supporting the first body member on the ground and adapted for controlling the direction of movement of the vehicle, a support bar supporting said steerable support member, and a seat for carrying a rider supported by said support bar and rigidly interconnected through said support bar to the steerable support member whereby pivotal movement of the seat effects similar pivotal movement of the steerable support member, a second body member including a pair of spaced apart steerable support members for supporting the second body member on the ground, said pair of steerable support members locked together in spaced and parallel directed relationship, a support frame supporting said pair of support members, and a first pivotal connection on said support frame, and a second pivotal connection on said support frame located rearwardly and upwardly relative to the first pivotal connection, said first and second pivotal connections establishing between them a pivotal axis, said first and second pivotal connections connecting the second body member to the first body member whereby the first body member is pivotable relative to the second body member, said pivotal axis being angled so as to intersect the ground between the steerable support member and pair of support members and sufficiently rearward of the steerable support member to effect lateral buckling between the support bar and support frame while turning, and said pivotal connections permitting pivotal swinging of the seat about the pivotal axis so as to effect side and rearward tilting of the single steerable support member for stabilized maneuvering of the vehicle.
