Devices and methods of transport are disclosed. Various embodiments include structural aspects related to steering and changing the direction of conveyances including features which utilize leaning or shifting of weight as part of turning.

A skateboard system includes a first suspension member having first through third portions, each portion having a largest flat planar surface. The first portion includes a plurality of mount holes to mount it with a skateboard deck. The largest flat planar surface of the second portion is angled between fifteen and sixty degrees relative to the largest flat planar surface of the first portion and relative to the deck. The largest flat planar surface of the third portion is angled between fifteen and eighty degrees relative to the largest flat planar surface of the second portion. The third portion includes at least one opening to mount a truck assembly and/or a hanger with the third portion. The first suspension member flexes, such that an angle between the largest flat planar surface of the second portion and the deck decreases, in response to a first downward force on the deck.

The subject of the invention is an in-line skate braking system designed to brake in-line skate wheels. This is achieved by an electric motor controlling the action of the brake segment on in-line skate wheels.

In a preferred embodiment a wheeled platform apparatus and method for use in rolling on a surface are provided. The apparatus includes a platform having a top surface, a bottom surface, a front portion, a center portion, a rear portion, and a first wheel and a second wheel that interface with or are positioned below the bottom surface of the platform to facilitate rolling movement of the platform. The apparatus may further include an attachment device interfacing with the top surface and the footwear, as well as a footrest to support the forefoot of another foot, or footwear.

A sport board or freestyle skateboard which may include at least a central aluminum honeycomb portion between layers of carbon nanotube fiber, fiberglass cloth, and covered with a soft outer layer.

A device which may include first and second cross skate bodies each having a frame configured to support at least first and second wheels situated inline of each other, each frame having at least one compartment configured to position a corresponding power source of first and second power sources; first and second foot couplers, each foot coupler configured to couple a foot of a user to a corresponding cross skate body of the cross skate bodies; a first traction motor coupled to drive at least one of the first and second wheels of the first cross skate body; a second traction motor coupled to drive at least one of the first and second wheels of the second cross skate body; and a controller which may be configured to: receive a drive signal from a drive controller, and control the first and second traction motors to drive the corresponding wheels in accordance with the drive signal.

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.
