Claim Text:
1. A foldable riding vehicle comprising: a frame having a front end and a rear end pivotally connected to the front end and being pivotal about a first axis, with the rear end including first and second pivot-connected ends, with the front end connected to a steering mechanism which includes a steering handle and which engages with a front wheel which is rotatable about a first axle, with the rear end having a first distal end pivotally connected to the front end and a second distal end engaging with a rear wheel which is rotatable about a second axle; a seat support pivotally connected to the rear end of the frame and supporting a seat, with the seat support including a third pivot-connected end connected to the first pivot-connected end and pivotal about a second axis and a fourth pivot-connected end; and a pedal mechanism movable between use and stowed positions, with the pedal mechanism including a carrier with a fifth pivot-connected end connected to the fourth pivot-connected end and pivotal about a third axis and with a sixth pivot-connected end, with the pedal mechanism including at least one linkage with a seventh pivot-connected end connected to the second pivot-connected end and pivotal about a fourth phantom axis and with an eighth pivot-connected end connected to the sixth pivot-connected end and pivotal about a fifth axis, and with the pedal mechanism including a bottom bracket engaging with and rotatable relative to the carrier about a sixth axis and coupling two pedal structures; wherein the first, second, third, fourth, fifth, and sixth axes are parallel to each other; and wherein the frame is movable between extended and folded positions; and wherein when the frame moves from the extended position to the folded position, the front and rear ends of the frame pivot in a first direction, the front wheel moves towards the rear wheel, the seat support pivots towards the front end of the frame, the seat support and the seat move towards the front end of the frame, the fifth axis moves towards the second axis, and the third axis moves away from the front end of the frame; and wherein when the frame moves from the folded position to the extended position, the front and rear ends of the frame pivot in a second direction, the front wheel moves away from the rear wheel, the seat support pivots away from the front end of the frame, the seat support and the seat move away from the front end of the frame, the fifth axis moves away from the second axis, and the third axis moves towards the front end of the frame; and wherein in the extended position, the steering handle is located symmetrically with respect to the frame, the pedal mechanism moves to the use position, the front wheel to be located distal to the rear wheel, and the front and rear wheels rotate on a surface; and wherein in the folded position, the steering handle is located symmetrically with respect to the frame, the pedal mechanism moves to the stowed position, the front wheel is located adjacent to the rear wheel, the front wheel is located at a higher height than the rear wheel and not to abut the surface, and the rear wheel rotates on the surface.
