The Segway 99997-00004 Mini Pro is the next evolutionary step of two-wheeled, self-balancing personal transporters. It goes beyond hoverboard technology by utilizing smarter software, stronger hardware, and safer features. The Segway miniPRO is the first electric scooter, before any hoverboard, to become UL 2272 Certified for the highest standards of electrical and fire safety requirements established by Underwriter Laboratories. It integrates with the Ninebot & Segway phone app to give you access to a wide array of premium features and functions, including remote control of the miniPRO without riding it, dashboard vehicle diagnostics, LED lighting customization, and a tamper-proof security alarm. The miniPRO's height-adjustable knee control bar allows the rider to maneuver more easily and precisely than other electric scooters and hoverboards. Rather than turn by pivoting each foot individually, riders steer by gentle pressing left or right on the knee bar. The miniPROs large, air-filled tires are rated for many indoor and outdoor terrains. These pneumatic tires absorb shocks better than the smaller, solid tires commonly found on hoverboards. The refined tread minimizes skidding and reinforces traction, keeping the rider safe and stable on the road.
