Hoverboards are quite simple to ride. The hoverboard goes forward, reverse, and you can maneuver it wherever you want to. The hoverboard also goes up on an incline, without having to put in any extra effort.
Learning to balance yourself, and go forward and backward will only require a couple of hours of practice. The concept of balancing is quite foreign to most people – however, the hoverboard does most of the work for you. Mastering the hoverboard, including maneuvering it here and there should take a couple of hours, maximum.
