A board apparatus that a user can ride and use to traverse inclines is disclosed. The board apparatus comprises an elongated board with a pivot wheel protruding through the board. A user of the board apparatus can stand on the board with feet in front and behind the pivot wheel, balancing a substantial portion of their weight on the pivot wheel. By adjusting their weight on the pivot wheel, the user is able to control the board's direction of travel. The board apparatus may further comprise a brake apparatus integrated to the pivot wheel that allows the user to maintain control over their speed as the board apparatus gains momentum going down an incline. The board apparatus may further comprise low friction elements at their front and/or rear ends to assist in maintaining momentum if the front or rear end comes into contact with the ground or an obstacle.

A multi-link wheel base includes a main body composed of a plurality of links connected in series and wheels provided on the main body, and the wheels are provided on the link assembly the link assembly includes an intermediate link and an end link, wherein both sides of the intermediate link are provided with a rotational connection position, one side of the end link is provided with a rotational connection position, and the rotational connection positions on the adjacent link assemblies are rotationally connected by means of a connecting device.

A mobility device comprising a motorized shoe to be worn by a user to increase the speed of walking. The motorized shoe has a plurality of wheels, with at least one wheel driven by an electric motor through a geartrain. On onboard controller gathers data from at least one of an inertial measurement unit, an ultrasonic sensor, and a vision system to generate a command speed to the electric motor. A user wearing a pair of the mobility devices, one on each foot, is able to walk with a normal gait, but at an increased speed.

Skating device (1) provided with a plurality of wheels (2a, 2b, 2c, 2d), comprising: an electric motor (3) operatively coupled with at least one wheel (2a) of said plurality of wheels; at least one acceleration sensor (4) operatively coupled with at least one wheel (2a) of said plurality of wheels (2a, 2b, 2c, 2d); at least one speed sensor operatively coupled with at least one wheel (2a) of said plurality of wheels (2a, 2b, 2c, 2d); and at least one control unity adapted to actuate the operations of said electric motor (3) at least when said acceleration sensor (4) detects positive acceleration of said at least one wheel (2a), wherein the amount of electric power supplied by said electric motor to said at least one wheel (2a) is calculated according to the speed measured by said at least one speed sensor (5), at least when said acceleration sensor (4) detects said positive acceleration.

A method of controlling a four-wheel skateboard, the method comprising: applying a load on an induction switch of the four-wheel skateboard, the induction switch starting a power switch of the four-wheel skateboard; driving the four-wheel skateboard to slide by the assistance of the load; controlling and starting a motor, by a controller of the four-wheel skateboard, to drive the four-wheel skateboard to slide; and taking the load off from the induction switch of the four-wheel skateboard and the induction switch shutting down the power switch of the four-wheel skateboard. The four-wheel skateboard relies on the load-assisted driving, not entirely on the driving force of the motor, so that the four-wheel skateboard consumes less electricity for sliding the same distance as conventional skateboards, requires relatively small amounts of lithium-ion batteries, and requires not too large battery capacity and not too high voltage, thus reducing the manufacturing cost of the four-wheel skateboard.

An illustrated side view of a skateboard brake device for providing braking to a wheel assembly of a skateboard is presented. The skate brake device is useful easily and safely apply braking to wheels of a skateboard when riding a skateboard. The skateboard brake device allows for a rider of the skateboard to apply the brakes without having to put a foot on the ground to stop the skateboard, instead the rider applies pressure to the skateboard brake apparatus using their foot. The skateboard brake device provides controlled braking for the skateboard. The skateboard brake device has a saddle and a foot pedal. The foot pedal is coupled to a neck of the saddle. The saddle has a first arm and a second arm protruding from it. The first arm and the second arm each have a brake pad coupled to it. The device is coupled to the bottom of a skateboard using a hinged bracket with springs. The hinged bracket is coupled to the bottom of the skateboard by screws and the middle portion of the saddle by screws into predrilled screw holes.

A flyboard comprising a base element and an upper element in communication with each other by magnetic fields having the same polarity and magnetic fields having opposite polarities to permit floatation of the upper element over the lower element while a user is standing on the upper element.
