The present invention discloses a smart balance wheel with a bolt-shaft structure, comprising a fixedly connected bearing and shaft system, a balance control and drive system, a safety control and prompt system and a charging system. The fixedly connected bearing and shaft system comprises a main frame and a shaft system. The main frame comprises a left frame and a right frame symmetric to each other and rotating relative to each other. The shaft system passes through the left and right frames to realize relative rotation. The balance control and drive system is located under the fixedly connected bearing and shaft system. The present invention uses a bolt-shaft structure and a closed dustproof structure, realizes fixing of the left and right main frames, increases connection strength and bearing capacity of the frame, improves safety of balancing, controlling and driving and improves the service life.

A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing.

An apparatus and method for a piston head assembly for an R/C car shock absorber provides for differing flow rates through the piston depending on whether the piston is presently in rebound or compression movement. A piston head may be constructed with a plurality of separate recesses further having at least first and second one way valve holes and a plurality of two way valve holes surrounding the central recess. In one embodiment, two sealing members fit within two separate recesses whereby the sealing member keeps the first and second one way valve holes generally closed. When fluid flow contacts the sealing member during the rebound stroke, fluid flows through the first and second one way valve holes moves the seal member to the open position thereby providing more fluid flow and a quicker rebound damping response.

A battery powered ride-on vehicle is provided that has vehicle body, a plurality of wheels, a battery dock, a battery having battery terminals that mate with battery dock terminals, an accelerator switch and an accelerator switch controller, a power line to allow current to flow between the battery dock and the accelerator switch controller, a plurality of electrical components, an electronics controller in electrical communication with the accelerator switch controller and the electrical components, a power line connecting the electronics controller with the accelerator switch controller to allow current to flow between the accelerator switch controller and the electronics controller, a timer that calculates the time between actuations of the accelerator switch, and when the time between actuations of the accelerator switch is greater than a timer threshold the accelerator switch controller prevents a release of current to the electronics controller until the accelerator switch is actuated again.

A ride-on vehicle is provided that has a speed controlled switching system. The ride-on vehicle has a vehicle body having a driver's seat, a plurality of wheels, a motor, a battery electrically connected to the motor, a direction switch assembly electrically connected between the battery and the motor, and a speed switch electrically connected between the direction switch assembly and the motor. The direction switch assembly has a forward button and a reverse button, and is proximal the driver's seat in the vehicle body. The speed switch has a high speed setting and a low speed setting and is distal the driver's seat and generally not accessible by a rider seated in the driver's seat. When the reverse button is actuated the direction switch assembly causes the voltage observed by the motor to be at the low speed setting regardless of the setting of the speed switch.

A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing.

A method of operating a personal transporter includes mounting the personal transporter. A torque stick apparatus having a rotating wheel is provided. The wheel of the torque stick apparatus is positioned against a drive surface to drive the personal transporter across a transport surface.

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 powered skateboard having a powered wheel. The powered wheel formed of a motor within tire of the wheel. The powered wheel fixed to a truck of the powered skateboard. The powered skateboard including at least one onboard battery to provide electrical power to the powered wheel.
