Abstract: Various powered unicycles are disclosed. In some embodiments, the powered unicycle includes a central wheel, a motor to power the central wheel, and a control system configured to control the application of power from the motor to the central wheel. The unicycle comprises a body portion and at least one platform for supporting the user. The unicycle can includes a handle that extends upwardly to a position that it can be grasped by a user of the unicycle. The handle can be partially or fully retractable into the body of the unicycle. In some configurations, two platforms upon which the user can stand are provided with one on each side of the central wheel. In some configurations, a pair of auxiliary or outrigger wheels is provided, such as with one outrigger wheel on each side of the central wheel.

Abstract: 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.

Abstract: 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.

Abstract: Various powered mobility systems, such as scooters and wheeled boards, are disclosed. The powered mobility system can be a drive assembly, which can include a motor, transmission assembly, driving wheel, and power supply. The drive assembly can be detachable from the rest of the personal mobility vehicle.

Abstract: A caster board can include a front platform, a rear platform, and at least two neck sections extending between the front platform and the rear platform. The neck sections can serve as a torsion element allowing twisting of the front platform relative to the rear platform. An aperture between the neck sections can be configured to receive an insert. The insert can alter a structural characteristic of the caster board, such as the torsional stiffness of the caster board.

Abstract: 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.
