A walker-shaped hoverboard attachment provides a center platform having a cavity and a rim around the cavity configured to rest on either side of a hoverboard's upper surface. Support rails and crossbars collectively configured as a walker may be fixedly connected to the platform. One or more brakes on one or more grips may enable a user to control the hoverboard while a user is standing on the platform.

A self-balancing board is provided, comprising a primary wheel assembly, a platform, at least one sensor, a controller, a first auxiliary wheel assembly, and a first brake element. The primary wheel assembly comprises a primary wheel and a motor driving the primary wheel. The platform is secured to the primary wheel assembly and has a foot deck. The at least one sensor senses the orientation of the platform. The controller receives data from the at least one sensor and controls the motor in response to the received data. The first auxiliary wheel assembly is secured to the platform distal the primary wheel assembly, and is elevated from contacting a flat surface upon which the primary wheel rests when the foot deck is parallel to the flat surface. The first brake element is manually movable relative to the first auxiliary wheel assembly to engage the first auxiliary wheel assembly to provide resistance to rotation of the first auxiliary wheel assembly.

A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.

An improvement to a traditional skateboard or traditional longboard with the addition of an attached, low-lying handlebar and riding methods. A traditional skateboard or traditional longboard limits riding positions or choices amid a standing position being standard riding practice. Although some riders attempt other riding positions, such as squatting, these unconventional riding positions are not technically pursuant to the current design, purpose, proper usage or intended use of a traditional skateboard or traditional longboard. These unconventional practices restrict board control and therefore increase the risk of injuries overall. The purpose of this improvement is to present the rider of a traditional skateboard or traditional longboard flexibility to implement different riding positions. With the attachment of a low-lying handlebar, the traditional skateboard or traditional longboard ultimately becomes a hybrid board allowing to ride kneeling or squatted. Additionally, there is an increase of board control and safety while in alternate riding positions.

A skateboard with hand brake comprises a skateboard, a handle and a hand brake.

A skateboard can be an ordinary skateboard or an electric motor skateboard.

The handlebar has an L shape.

The end of the lower part of the handle is fitted to the hanger of the front truck of the skateboard.

A hand brake comprises a brake lever, a brake cable and a brake module.

A brake lever is fitted to the upper part of the handle and a brake cable connects the brake lever to the brake module that is fitted underneath the deck.

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 user powered ride-on device and assemblies to facilitate ride-on device reconfiguration.

A self-balancing board is provided, comprising a primary wheel assembly, a platform, at least one sensor, a controller, a first auxiliary wheel assembly, and a first brake element. The primary wheel assembly comprises a primary wheel and a motor driving the primary wheel. The platform is secured to the primary wheel assembly and has a foot deck. The at least one sensor senses the orientation of the platform. The controller receives data from the at least one sensor and controls the motor in response to the received data. The first auxiliary wheel assembly is secured to the platform distal the primary wheel assembly, and is elevated from contacting a flat surface upon which the primary wheel rests when the foot deck is parallel to the flat surface. The first brake element is manually movable relative to the first auxiliary wheel assembly to engage the first auxiliary wheel assembly to provide resistance to rotation of the first auxiliary wheel assembly.

An apparatus for receiving one or more activity attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a circular aperture for receiving an accessory of a set of accessories. Each accessory of the set of accessories providing an activity for a user of the activity. Each accessory having an attachment platform configured to attach the accessory to the board. The attachment platform having a locking mechanism to engaging with a complementary locking mechanism of the board.

A roller board device like a skateboard or scooter operated by a user with one or more user-maneuverable wheel assemblies that are automatically returned to their true north position is provided according to the invention. The roller board device comprises an elongated deck., at least one wheel assembly, a rotation assembly operatively engaging and extending through the opening in the deck, one end of the rotation assembly being connected to the wheel assembly positioned below the deck, the other end of the rotation assembly being connected to a user interface member extending upward beyond the top surface of the deck, and a north-seeking return mechanism secured to the deck containing an engagement member movable along a linear axis within a housing and engaging a spring disposed between the engagement member and an interior wall of the housing, the rotation assembly operatively connected to the engagement member to convert rotational movement of the rotation member into linear movement of the engagement member. When the user applies rotational force to the user engagement member to turn it to the left or right, the rotation assembly and wheel assembly are rotated in the same direction and degree to allow the roller board device to be turned, the rotated rotation assembly interacting with the engagement member of the north-seeking return mechanism to move the engagement member along its linear axis to a retracted position to compress the spring. But, when the user releases the rotational force upon the user interface member, the spring extends from its compressed state to its elongated state to move the engagement member of the north-seeking return mechanism back along the linear axis from its retracted position to its standby position, counter interacting with the rotation assembly to return the wheel assembly of the roller board device to its true north position.
