A skateboard is a wheeled device used for recreational and sports activities. It consists of a flat board with four wheels attached to the underside, allowing riders to propel themselves by pushing off the ground with one foot while balancing on the board. Skateboarding involves performing various tricks and maneuvers, such as ollies, kickflips, and grinds, often in skate parks or urban environments. It is a popular activity among individuals of all ages and is associated with creativity, athleticism, and a sense of freedom.
