Disclosed is a self-balancing vehicle including a left housing assembly, a right housing assembly, a left wheel train, a right wheel train and a rotation mechanism. The left wheel train is connected with the left housing assembly. The first end of the rotation mechanism is connected with the right wheel train and the right housing assembly, and the second end of the rotation mechanism is inserted into the left housing assembly and rotationally connected with the left housing assembly. The rotation mechanism is just arranged in the right housing assembly, but connected with the right housing assembly and the right wheel train respectively, thus reducing the strength requirements of the self-balancing vehicle on the left housing assembly and simplifying the components of the left housing assembly.

A self-balancing vehicle includes a vehicle body having a housing with left and right sides which are independently moveable. A unitary support bar is disposed within the housing, and a left drive wheel and an opposed right drive wheel are each coupled to the support bar. A bracket encircles the support bar; the bracket has a cylindrical body formed with a slot through the body. A set screw is fixed to the support bar and is received within the slot to limit rotational movement of the support bar with respect to the bracket.

Apparatus and systems are provided that enhance the use of a one wheel skateboard. Some of the apparatus described provide lateral surfaces that engage outer portions of a user's feet. Other apparatus facilitate the engagement of common snowboard bindings to a one wheel skateboard, thereby widening the spectrum of tricks that can be performed.

A steering system for a snowboard includes two binding interface pods, one of which may be active and one of which may be passive. Rotation or tilting of a top plate of the active binding interface pod in response to rotation or tilting of the rider's steering foot causes counter-rotation of a steering fin under the rider's steering foot. The passive binding interface pod is responsive via a linkage between the active and passive binding interface pods to cause rotation of a steering fin under the rider's non-steering foot. Coordinated counter-rotation of the steering fins causes the board to turn in the direction of rotation of the rider's steering foot when the steering fins are unaligned. Optionally, both binding pods may be active in steering, i.e. enabling two footed steering.

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.

A fore-aft self-balancing transportation device, typically in a pair, one for the right foot and the other for the left foot of a rider. The platform is limited in size and positioned with a top surface wholly above the drive wheel, such that the platform straddles the axis of rotation of the drive wheel. The wheel may extend laterally to enhance side-to-side stability. The devices are configured for hands-free control, a device being driven forward or backward in response to the fore-aft tilt angle of a rider's foot on the platform (and hence, the fore-aft tilt angle of that platform). Various embodiments and features are disclosed.

An auto-balancing transportation device having a compact form. Left and right foot platform sections are coupled for fore-aft tilt angle movement relative to one another. Left and right wheels are provided under the respective foot platforms. With a rider's weight directed primarily downward onto the wheels and not onto the coupling structure, the coupling structure may have sufficient space to house the battery. In addition, more efficient and lighter weight supports and bearing arrangements may be used in the coupling structure. Various embodiments are disclosed.

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.
