Abstract: According to an aspect, there is provided a vehicle system that includes a foot-deck-based vehicle and a seat accessory structure. The foot-deck-based vehicle includes a foot deck, a handle structure and a plurality of wheels. The foot deck is positioned to support—a user and includes a first handle structure receiving feature. The handle structure is detachably connectable to the first handle structure receiving feature. The seat accessory structure has a seat body and is detachably connectable to the foot deck so as to form a seat-based vehicle. The seat accessory structure has a second handle structure receiving feature thereon. The handle structure is detachably connectable to the second handle structure receiving feature, so as to be positioned for gripping by a secondary person when the secondary person is urging the seat-based vehicle to roll on the ground surface while the user is seated on the seat body.

Abstract: In an aspect there is provided a swing scooter, comprising a frame, a steering member, a front wheel, at least two support legs, and at least two platforms. A rear wheel support is pivotally attached each support leg. A rear wheel is rotatably attached to each rear wheel support. Each platform is movably attached to an associated support leg, and positioned for supporting a foot of a user. Each platform has a longitudinal platform axis and is movable between a first position in which the platform is angled down laterally towards a first lateral side of the swing scooter, and a second position in which the platform is angled down laterally towards a second lateral side of the swing scooter. The platform is movable to the first and second positions by movement of the foot of the user.

Abstract: In an aspect, a pivot joint for a collapsing foot-deck-based vehicle is described, comprising a foot deck, at least two wheels coupled to the foot deck, and a handlebar assembly coupled to the foot deck via a locking pivot joint, also referred to as a locking swivel joint, the handlebar assembly comprising at least one handle, the locking pivot joint having a pivot axis that is generally unparallel with a horizontal plane defined by the lowermost surfaces of the at least two wheels, the handlebar assembly being selectively pivotable via the locking pivot joint between a riding configuration in which the handle is generally distal from the foot deck and a collapsed configuration in which the handle is generally proximal to the foot deck.

Abstract: In an aspect, a collapsing foot-deck-based vehicle is provided and includes a foot deck, at least two wheels coupled to the foot deck, and a handle structure coupled to the foot deck via a locking pivot joint. The handle structure includes at least one handle. The locking pivot joint has a pivot axis that is generally unparallel with a horizontal plane defined by the lowermost surfaces of the at least two wheels. The handle structure is selectively pivotable via the locking pivot joint between a riding configuration in which the handle is generally distal from the foot deck for gripping by a rider of the foot-deck-based vehicle, and a collapsed configuration in which the handle is generally proximal to the foot deck.

Abstract: A foot-deck-based vehicle having an adjustable steering characteristic is provided. The foot-deck-based vehicle has a foot-deck with a front end, a rear end, and at least one rear wheel proximal to the rear end. A front wheel assembly is coupled to the foot-deck proximal to the front end to pivot relative to the foot-deck about a front wheel assembly pivot axis that is at an acute angle to a vertical axis when the foot-deck-based vehicle is upright. The front wheel assembly includes at least one front wheel rotatably coupled to a front wheel support. A steering characteristic adjustment structure adjustably controls a steering characteristic of the foot-deck-based vehicle.

Abstract: In an aspect a vehicle is provided, and includes a frame a front wheel and a rear assembly. The front wheel is rotatably mounted to the frame. The rear assembly includes a first rear wheel support and a second rear wheel support. Each of the wheel supports is movably mounted to the frame. The rear assembly further includes a first rear wheel and a second rear wheel. The first and second rear wheels are rotatably mounted to the first rear wheel supports respectively. The rear assembly is positionable in a first position in which the first and second rear wheels are substantially immediately adjacent one another to operate as a single rear wheel, and a second position in which the first and second rear wheels are spaced apart from one another.

Abstract: The improvement of the invention is a permanent fixed or removable carriage for a third inline scooter wheel behind a second scooter wheel that allows the user to ride the scooter in an inclined position simulating a single wheel ride referred to as a “Wheelie” or a “Manual”. The key is to place the third wheel within a range of 100 millimeters from the second wheel and a vertical distance variations of 25 millimeters to wheel enable a rider to achieve this Wheelie effect, where the angle of the scooter can be raised to twenty (20) and even to thirty (30) degrees.
