Provided are a self-balancing scooter and a control method thereof, and a kart powered by the same. The self-balancing scooter includes two scooter bodies on which foot boards and motorized wheels are disposed, and a rotating shaft device, where the rotating shaft device includes a rotating shaft, two axle seats, and a torsion limiting mechanism. The torsion limiting mechanism controls a rotation angle by the fit between a limiting portion on the rotating shaft and a fitting portion on one axle seat. The present disclosure realizes torsion limit by directly using the rotating shaft and the axle seats without the use of an additional element (for example, a limiting shaft), thus simplifying the structure of the rotating shaft device and facilitating assembly.

A rugged and compact articulated wheel with at least two hubs, and wheeled vehicles that include one or more of such articulated wheels.

Systems and methods for collecting electric scooters are described herein. In some embodiments, the systems and methods facilitate a “snaking” configuration of attaching, coupling, or fixing multiple electric scooters to one another. The snaking configuration enables multiple electric scooters to be collected together and moved to various locations, such as locations where the electric scooters can be rented, serviced, and so on. Further, the systems and methods enable any electric scooter to act as a collecting scooter, and thus a scooter share service or other fleet of scooters can manage the collection and provisioning of scooters in a location without special vehicles or equipment, among other benefits.

A kit of a scooter and a scooter are provided. The kit includes: a deck assembly; a first steering assembly arranged to a first end of the deck assembly; a driven wheel assembly arranged to the first steering assembly and configured to rotate relative to the deck assembly through the first steering assembly; a second steering assembly arranged to a second end of the deck assembly; a connecting device arranged to the second steering assembly and configured to rotate relative to the deck assembly through the second steering assembly. The connecting device is a device of the kit configured to be connected to a power wheel assembly.

An electric scooter includes a deck, a power wheel unit, a power wheel steering unit, a driven wheel, a driven wheel steering unit, a power supply unit and a whole scooter controller. The power wheel unit includes a driving wheel; the power wheel steering unit is arranged between the deck and the power wheel unit; the driven wheel is spaced apart from the power wheel unit; the driven wheel steering unit is arranged between the driven wheel and the deck; the power supply unit is electrically coupled to the power wheel unit; the whole scooter controller is in communication with the power wheel unit and controls rotation of the driving wheel.

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.

Am adjustment device reusable on equipment such as sports equipment for children or as a pram, pushchair, stroller or similar device to adjust the spacing between wheels of such equipment. The adjustment device includes at least one slider body comprising a curved guide track disposed on the body of the equipment mirror-symmetrically to the longitudinal principal plane of the at each side of said longitudinal principal plane, the slider body comprises a sliding member that is configured to correspond in size and shape to the curved guide track of the slider body, and can be displaced along the curved guide track of the slider body, with the curved movement paths of the sliding members and the centrelines of the guide tracks of the slider body constituting mutually corresponding circular arcs.
