The age of the “hoverboard” is over. The Segway miniPRO is the next evolutionary step of two-wheeled, self-balancing personal transporters. Segway and Ninebot utilized decades of combined industry knowledge to create smarter software, stronger hardware, and safer features. The miniPRO’s precision sensors automatically react to the rider’s movements and maintain stability over a variety of indoor and outdoor terrains. The knee control bar provides innovative steering precision that allows you to maneuver more effectively than two-wheel hover boards.
The Segway miniPRO is the first personal transporter, before any hoverboard, to become UL 2272 Certified for the highest standards of electrical and fire safety requirements established by Underwriter Laboratories. Not only does it come with the highest fire and electric safety certification, but it also integrates with the Ninebot & Segway phone app to give you access to a wide array of premium features and functions. From the app, you can remote control the miniPRO without riding it, view dashboard performance, customize lighting on the unit, and enable a tamper-proof security alarm.
