Ever thought about how cool it would be to turn your hover board into a go-kart? Me either. But MonoRover has accomplished just that. It looks fairly easy to hook up and then controls similarly to how you control your hover board with your feet except you use the handles. Push both handles towards the ground so it will go forward and pull back towards you so it will go backward. Push down on the right handle to go left and vice versa. You can add on to any 6.5, 8 or 10-inch hoverboard for endless fun. Move fast while it’s on sale for just $150.
