A wheel includes a primary ring having a stepped core part and a tire formed of a urethane material as an outer surface thereof, and an auxiliary ring provided on a circumferentially-central portion of the primary ring, on which the tire is provided, in an insertion manner. The primary ring is formed of a plastic material, and the auxiliary ring is formed of a metallic material that is different from the material of the primary ring.

Embodiments disclosed herein describe systems and methods for a bead lock wheel line in scaled vehicles. The bead lock wheel line may include a wheel center section and a bead lock ring. The bead lock ring may be configured to be overlaid on the wheel center section, wherein screws may be inserted through orifices positioned within the bead lock ring and into orifices positioned on the wheel center section.

A wearable motorized device comprising a shoe bracket, which can be fastened to a shoe; wheels that are installed on the left and right sides of the shoe bracket in parallel to support the wearer's lateral skating and longitudinal walking; a driving motor for rotationally driving the wheels; and a battery pack for powering the driving motor. The wheels are not coaxially installed on the two sides of the shoe bracket to drive the wearer's longitudinal skating, but instead are installed on the two sides of the shoe bracket in parallel to drive the wearer's lateral skating; the wearer can position his/her legs apart during skating, so the skating stability is improved. Its general contour does not significantly exceed the contour of the shoe in the longitudinal direction, thus and it will not strain the wearer when ascending or descending stairs.

The present invention relates to a foldable tricycle, operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an attendant pushing the tricycle. The tricycle comprising: a pair of rear wheels, each rotatably supported by a rear support; a foldable seat comprising a chair and a back support, for accommodating said tricycle rider; a foldable arm rest, connected to said foldable seat; a parental handle, for steering said tricycle by said attendant pushing the tricycle; a main frame, configured to rotatably hold said rear support, to support said foldable seat, to rotatably support said rider handle, to rotatably support said fork; and a latching mechanism, capable of locking and unlocking the rotatable movement, of the rear support, in relations to the main frame.

A number of variations may include a foldable scooter comprising a first frame component, wherein the first frame component comprises a steering column and a handlebar, wherein the steering column is integrated with an electric drive unit speed controller which is constructed and arranged to operatively control a removeable electric drive module; a second frame component, wherein the second frame component is rotatably attached to the first frame component so that the first frame component can fold onto the second frame component and wherein the second frame component includes a deck; a front wheel operatively connected to the first frame component; and a rear wheel operatively connected to the second frame component.

The system disclosed and claimed herein is an electric propelling wheel and battery/motor control subsystem enabling the retrofitting of a standard skateboard, having standard truck and wheels, with electrical propulsion capabilities.

Various embodiments of an airless tire are disclosed. In some embodiments, the tire can include a hub and a tread. A cushioning unit can be positioned between the hub and the tread. A support can be positioned between, and can provide structural support to, the cushioning unit and the tread.

The two-axle vehicle balance scooter includes an upper shell, lower shell, pedal, pressure sensors, brackets, wheels, press block, shaft, chip, and battery pack. The brackets include a pedal bracket, hardware support, battery support and chip support. The press block includes a wheel pressure block and an axial compression block, from bottom to top on the housing gasket installed the pedal bracket and pedals. Both sides of the body are disposed around a middle section that is a battery holder below which a battery is installed. Accordingly, the scooter is symmetrical thus providing better stability, easier handling, easy installation and removal of a battery and other benefits.

A modular motorized drive system for skateboards allows users to quickly and easily swap out electronics, battery packs, motors, and other components on their skateboards with replacement or upgraded components. Users can thereby keep their skateboards for long periods of time without the skateboards becoming outdated. The modular motorized drive system also allows users to easily convert non-motorized skateboards into motorized skateboards. The modular drive system can be mounted on most skateboards on the market using both the new and old school industry-standard truck mounting patterns.

A child drift car comprises a car frame, a wheel assembly, a seat, a driving mechanism and a direction control mechanism; the wheel assembly comprises a driving wheel assembly, and the driving wheel assembly comprises driving wheels, and an axle fixedly connected to the driving wheels; the driving mechanism comprises a driver and a transmission device; the direction control mechanism comprises a steering column, a steering wheel fixedly connected to the steering column, and a steering device separately connected to the steering column and the driving wheel assembly; the driving mechanism further comprises a main shaft rotatably disposed on the car frame along its own axis and driven by the transmission device to rotate, and the main shaft is connected to the axle through a universal joint. When the driving wheels turn, the speed of the driving wheels is not affected, and a higher drifting speed can be achieved.
