Longboarding is a fun thing to do and is enjoyable for a lot of people but it's a pain to carry them around. For example, if you were going on the train or the bus there isn't much space to have a longboard. Our product uses a simple sliding mechanism to expand and contract the board. With this mechanism, we can shorten the longboard from a length of 44 inches down to a length of 12 inches. Once it slides into its 12-inch form it can then fold in half and fit in your backpack.
