Due to increased demands of portable electricity, during outdoor activities, the handle 10 allows a means to easily carry and supply electricity for devices.

Sports equipment comprising a ski (1) and a lift group (G); the ski (1) comprises a longitudinal axis (Z), a tip (11), a tail (12), two lateral edges (13) and a bridge-like structure (15), arranged between the tail (12) and the tip (11), above the ski (1); the bridge-like structure (15) comprises a hooking surface (15a) for bindings (AT) of a user's boot and defining, on a lower side, a duct (16); said lift group (G) comprising an engine unit (M) comprising a motor (2) and a drum (4) moved by the motor (2), a management and control unit (U) connected to the motor (2), a first roller (51) arranged on the tip (11) of the ski (1), a second roller (52) arranged on the tail (12) of the ski (1) and a belt (6) closed on itself and wound longitudinally around the ski under a condition for which it slides around the two rollers (51, 52), being dragged in rotation by the above-mentioned drum (4) and being slidingly inserted on the duct (16); the belt (6) is equipped with a rib sliding in a groove of the ski (1).

An electric weight sensing skateboard using one or more strain gauge systems to detect rider-induced strain on one or both trucks, an inertial sensor to detect accelerations and balance position, and wheel speed sensors. Throttle is controlled by rider position, for example, lean forward to increase speed, lean back to slow down. Several drive methods include a driver position detection velocity setpoint control, torque setpoint control, and direct velocity/torque control. A throttle remote is note required. Rider weight activates the motors.

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 personal transport system is provided including, in an embodiment, an electrically powered vehicle, a companion remote control, and a companion mobile phone application. The vehicle includes an operator-supporting deck, one or more deck-mounted trucks, one or more axle-mounted wheels on each of the one or more trucks, one or more batteries, and a deck lighting system. The one or more batteries power a motor configured to drive the wheels by way of a pulley system, at least one battery of which is disposed under a battery enclosure. The battery enclosure has a first light indicator system, and the companion remote control has a second light indicator system, each of which is configured for communicating with the operator. The deck lighting system includes a light strip of light-emitting diodes disposed in a groove of the deck configured to change state to communicate with the operator or others sharing a road.

An apparatus and method for reducing the incidence of sudden stoppage while riding a self balancing skateboard. Wheels are mounted with the front of the bumper, or integrated within a special replacement bumper, of the skateboard to provide a low-friction rollout instead of an instant stop, allowing the rider to maintain control in the event that the front of the board contacts the ground. The wheels protrude from a lower surface of the bumper to limit contact of the bumper with the ground.

A motorized vehicle assembly includes an axle comprising a channel extending along a central axis of the axle, a socket positioned within the channel of the axle, and a motorized wheel configured to be mounted on an end the axle. The motorized wheel includes a boss configured to engage the end of the axle when the motorized wheel is mounted on the axle, an electric motor, a tire mounted on the rotor, and a plug positioned within the boss, the plug configured to engage with the socket when the motorized wheel is mounted on the axle. The electric motor includes a stator fixed to the boss and a rotor surrounding the stator, the rotor configured to rotate relative to the stator. The electric motor is configured to cause the rotor to rotate relative to the stator to cause the tire to rotate.

A self-balancing vehicle includes a vehicle body having a housing with a top cover and a bottom cover. It includes a unitary support bar disposed between the top and bottom covers, about which the top and bottom covers are mounted, and which extends entirely along the top and bottom covers between opposed left and right ends of the unitary support bar. The vehicle further includes a left drive wheel and an opposed right drive wheel, each indirectly coupled to the unitary support bar.

The novel system of the present invention includes a plurality of moveable markers, such as cones, having two visually contrasting indicators useful for physically and visually demarcating activity zones. The markers can be dispersed spatially, such as being placed on the ground or on posts, to demarcate areas, zones, regions or boundaries, for conducting an activity, such as soccer practice. The system is useful to guide, instruct, monitor or constrain the activity of an individual, or object. Alignment of the markers can visually separate one zone from another zone so as to indicate different activities for each zone.
