Actually, there is no active suspension mechanism involved in a hoverboard. In spite of a lack of a suspension mechanism, the hoverboard can take quite a few rough roads. This doesn’t mean you go ahead and drive it on bumpy, bouncy roads. Hoverboards are quite delicate but can handle bumps in the road, about ¼ to ½ inch.
As you get more and more comfortable with your board, you will realize how a passive suspension mechanism works while riding. You can use your knees to serve as suspension – bend them a little, according to your liking.
