Scooter

A scooter device that can be propelled by side to side movement of a user is disclosed. The scooter device includes at least a first front wheel, at least a second and a third rearward located wheel, a frame structure through which the first wheel is coupled to the second and third wheels, wherein the second and third rearward located wheels are mounted in a biased direction arrangement and a steering mechanism that has a vertically ascending control member and is coupled to the first wheel such that turning of the steering mechanism achieves a turning of the first wheel, the steering mechanism further coupled to the frame structure such that the steering mechanism may be tilted relative to the frame structure. The frame structure can includes a first foot placement platform extending above the second wheel and a second foot placement platform extending above the third wheel.

Scooter with rotational connection

A caster board can include a front platform section connected by a torsion bar or other neck portion to a rear platform section. The caster board can be convertible between a first configuration in which the caster board has three wheels, and a second configuration in which the caster board has two wheels. In the first configuration, the rear platform section can be supported by two wheels laterally offset from a longitudinal axis of the caster board. In the second configuration, the rear platform section can be supported by one wheel aligned with a longitudinal axis of the caster board. The rear platform section can include at least three mounting locations configured to have caster assemblies installed therein.

Convertible caster board

Personal mobility vehicle

Various powered mobility systems for users are described. The powered mobility system can include at least one powered skate. The powered skate can include a platform, a plurality of wheels, and a motor assembly. The motor assembly can include a motor. The motor can be powered by a power supply. A motor control can be implemented to determine when power is supplied to the motor from the power supply.

Various hub motor arrangements, systems, and methods are disclosed. The hub motor arrangement may include a transmission assembly to provide increased torque. The transmission assembly may include a motor gear, a planetary gear, an idler gear, and a ring gear. The idler gear may be positioned farther away from an axis of rotation of the hub motor arrangement compared to the planetary gear. The motor gear may drive the planetary gear, the planetary gear may drive the idler gear, and idler gear may drive the ring gear. The rotation of the ring gear may rotate a housing of the hub motor arrangement to propel a vehicle incorporating the hub motor arrangement.

Hub motor arrangements, systems, and methods

Various electric balance vehicles are described. In some embodiments, the vehicle has first and second housings with platforms to support a user's feet. The first and second housings can be rotatable relative to each other. The vehicle can have first and second wheel assemblies. A support member can extend within tapered portions of the first and second housings. In some embodiments, one of the first and second housings can rotate relative to the support member and the other of the housings can be rotationally fixed relative to the support member. The vehicle can balance and provide locomotion to the user. The vehicle can be light, compact, and/or have a low center of gravity.
