I have always found standing on a “hoverboard” to get around a bit silly. Turning your hoverboard into a GoKart is probably a better idea. The Hoverboard Cart lets you do just that. It is easy to set up and drive. You can attach your favorite beach chair to the aluminum frame to get started.
The Hoverboard Cart can be ridden over grass, gravel, and packed sand. It is strong enough to pull a kayak down to the beach. More information is available here.
