The disclosure relates to a skateboard and control method thereof. A skateboard deck is fixed on an axle of the skateboard, and a first sensor group and a second sensor group are sequentially arranged on the skateboard deck in a width direction. The method includes acquiring a first pressure value of the first sensor group and a second pressure value of the second sensor group; controlling the skateboard to turn to a first direction when the first pressure value is greater than the second pressure value and a difference value between the first pressure value and the second pressure value is greater than a first threshold, and controlling the skateboard to turn to a second direction when the second pressure value is greater than the first pressure value and a difference value between the second pressure value and the first pressure value is greater than a second threshold.

A braking system having a rotating element that rotates about an axis, and a braking device for braking the rotating element. The braking device has a first braking element that is movable between a rest position and a braking position and has an annular braking surface which is arranged concentrically with respect to the axis and has a brake disc which is co-rotationally connected to the rotating element and has first and second frictional surfaces. The annular braking surface of the first braking element is arranged at a distance from the brake disc in the rest position, and is in contact with the first frictional surface thereof in the braking position. A second braking element is arranged such that in the braking position the first braking element presses the brake disc against the second braking element such that the second braking element is in contact with the second frictional surface.

Soft-tipped pole designs and methods for their use on pavement are disclosed. The soft, gripping pole tip can slow down a roller skier or skateboarder by slowing down the rider directly and by providing increased rider stability during breaking. This is accomplished by the rider pressing one or two pole tips against the pavement, with or without the use of a fulcrum point for increased leverage. The soft rubberlike tip has a large surface area that provides durability as well as variable levels of frictional force imparted against the pavement. The fulcrum for the pole can be the user's arm or leg as well as fulcrum element fastened to the rolling device.

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.
