Nothing can stand in your way with Flexup. This single-wheeled device allows users to weave through city streets effortlessly, providing them unparalleled mobility. With a small repulsive force between individual motions of expanding tread blocks, this electromagnetic force-activated transporter allows smooth riding on obstacles and even on stairs. Flexup can freely turn corners on flat ground by using the tilting principle inspired by skiing motions. The user controls the direction according to the up and down behavior of the left and right footrests.
