This is the world’s only stackable and expandable skateboard ramp. Locking together various geometric shapes, skaters can build their own ramp system. Rubber feet keeps the product in place while plastic connectors accommodate a child's physical growth (it can even withstand a weight capacity of up to 300lb.). Such flexability and durability preclude the need for older skaters to upgrade. In six months, the product has sold forty $200 combination kits, consisting of two ramps and one deck, surpassing other items comparable in price to become a top feature on Jump USA, America’s #1 sports training superstore.
