A halfpipe is a U-shaped structure commonly used in extreme sports such as skateboarding, snowboarding, and surfing. It consists of two opposing sloped walls, enabling riders to perform tricks and maneuvers by gaining momentum as they transition from one wall to the other. The design allows athletes to achieve airborne maneuvers while providing the gravitational pull necessary for returning to the ramp. Halfpipes are typically constructed of materials like wood or metal and can vary in size and steepness, influencing the difficulty and type of tricks that can be executed. They are popular features at skate parks, snowboarding resorts, and competitive events, where riders showcase their skills in halfpipe competitions. The term “halfpipe” specifically refers to the shape and functionality of the ramp rather than the specific activity of riding it.
