The technology built into a Segway consists of intelligent sensors, robust mechanical components and a steering mechanism that maintains balance and allows you to ride on two wheels.
When you climb onto a Segway, five electrostatic gyros and two accelerometers instantly detect the slope of the surface you are on and the way you are standing on the machine. They do this 100 times a second!
If you stand upright on a Segway, without leaning in any direction, it will stand still and maintain the balance. If you lean forward, backward or to the side, your Segway will immediately recognise this and compensate for the movement by going in that direction at exactly the speed you want. If you stand straight up, it will gently come to a stop.
