So you love using hoverboards but would love to use them in a safer fashion? HoverBars may help. They improve your stance, allowing you to hold on while you hover. There are also safety wheels that keep you steady when you begin to fall.
HoverBars provide you with handles to support your upper body. They also make it easier to steer your hoverboard. You can also adjust the height of the safety wheels. The developers are raising funds for it on Kickstarter.
