Provided is an accessory for a self-balancing board having two lateral foot-deck ends, each being coupled to a motor that drives a wheel in response to its orientation. The foot-deck has at least one sensor that is triggered when a rider is in a riding position thereon. The accessory includes a chassis, at least one travel surface-contacting element, a seat, and an engagement structure that releasably engages the self-balancing board. At least one sensor-triggering element is actuatable between an idle position and a triggering position, wherein the at least one sensor-triggering element triggers the at least one sensor. At least one control member actuates at least one of the engagement structure and the at least one sensor-triggering element to control the orientation of the lateral foot-deck ends. At least one manually actuatable actuator actuates the at least one sensor-triggering element between the idle position and the triggering position.

A powered board vehicle can include a deck having a support surface, a rear wheel assembly, and a front wheel assembly. The support surface can include a forward portion, a rearward portion, and a neck that connects the forward portion with the rearward portion. The forward portion, the rearward portion, and the neck can be integrally formed. The rear wheel assembly can include a powered rear wheel. The front wheel assembly can include at least one front wheel configured to swivel about a first axis and rotate about a second axis.

Skateboard having a board with a first platform and a second platform, fastenings fixed to the board, wheels rotatably mounted in the fastenings in order to move the board, a first frame-fixed to the first platform and a second frame fixed to the second platform, and connection means rotatably connecting the first frame to the second frame in such manner that the skateboard can be in an open position, in which the first platform and the second platform are aligned and coplanar, and in a closed position, in which the first platform and the second platform are parallel and disposed on different planes.

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.

An accessory for a self-balancing board is provided. The self-balancing board comprises a foot-deck having two lateral foot-deck ends. Each lateral foot-deck end is coupled to a motor that drives a wheel in response to an orientation of the lateral foot-deck end relative to a horizontal plane. The accessory includes a chassis, at least one travel surface-contacting element coupled proximal to a first longitudinal end of the chassis to facilitate travel of the chassis over a travel surface, and a seat coupled to the chassis and configured to support a person. The accessory further includes a first foot-deck engagement element proximal to a second longitudinal end of the chassis distal to the first longitudinal end and constructed to engage the foot-deck of the self-balancing board proximal to the first lateral foot-deck end, and a second foot-deck engagement element proximal to the second longitudinal end of the chassis and constructed to engage the foot-deck of the self-balancing board proximal to the second lateral foot-deck end. At least one control member coupled to the first foot-deck engagement element and the second foot-deck engagement element controls the orientation of the lateral foot-deck ends relative to a horizontal plane via the first foot-deck engagement element and the second foot-deck engagement element.

Various powered wheeled board vehicles are disclosed. In some embodiments, the vehicle includes a deck having a forward portion and a rearward portion. At least one front wheel can be connected with the deck under the forward portion. The front wheel can be configured to swivel about a first axis and rotate about a second axis. A powered wheel can be connected with the rearward portion. In some configurations, the rear wheel comprises a hub motor.

Skateboard having a board with a first platform and a second platform, fastenings fixed to the board, wheels rotatably mounted in the fastenings in order to move the board, a first frame-fixed to the first platform and a second frame fixed to the second platform, and connection means rotatably connecting the first frame to the second frame in such manner that the skateboard can be in an open position, in which the first platform and the second platform are aligned and coplanar, and in a closed position, in which the first platform and the second platform are parallel and disposed on different planes.

The present invention is a personal mobility device having multiple modes of operation, including a deck, and a first and second wheel assembly, and at least one battery powered electric motor, and actuation means. The deck includes an elongate substantially flat body, and each wheel assembly is attached to the deck in the vicinity of a respective end of the elongate body. The respective axle of each wheel assembly is located upon the plane of the deck. The at least one battery powered electric motor is adapted to be actuated via the actuation means when a user steps onto the deck, and adapted to drive the first and second wheel assemblies, and wherein in the first mode of operation, both the first and second wheel assemblies are adapted to roll in a circumferential direction, predominately under the influence of the at least one electric motor, so that the device moves in an orthogonal direction to the longitudinal axis of the deck, and wherein in a second mode of operation, both the first and second wheel assemblies are also adapted to optionally free-roll in an orthogonal direction to the plane of the wheel assembly, thereby allowing the device to move substantially in the direction of the longitudinal axis of the deck. There is a transitional mode of operation, where the device is capable of continuously and smoothly transitioning between the first and second mode of operation, while the device is being ridden.

Various powered personal mobility vehicles are disclosed. In some embodiments, the vehicle can include a deck having a forward portion, a rearward portion, and a neck portion. A front swivel wheel assembly and a rear swivel wheel assembly can be connected with the deck. In some embodiments, the front swivel wheel assembly comprises a motor.

A bifurcated spring-tethered electric skateboard is bifurcated into a front deck and rear deck with each deck having independently powered wheels. The skateboard has a mounted power source, generating electrical power for a motor that is transmitted to the wheels. A controller is configured to control the speed of the motor, and the wheels. The controller is electrically connected to the motor for direct control, or a wireless transmitter for remote control. A spring assembly connects the decks, creating a spring-tensioned effect between the decks while riding the skateboard. The uneven ride requires that the trucks do not rotate fully. A cable that connects the electrical components can also be damaged from excessive rotation of the trucks. Thus, the skateboard also provides a restriction tab at the bottom surface of the decks that engages the trucks to limit rotations thereof.
