This high-strength lightweight skateboard with an adjustable wheelbase is made of hollow magnesium alloy. By dispensing with wood, the designers have created a product that is both ecological and ultra-light. Fittingly, the design was inspired by the structure of a leaf, which is light, flexible and high in strength. The four main design advantages of this skateboard are that it does not slip, absorbs shock, has an adjustable wheelbase, and turns smoothly.
