Segway: the first self-balancing means of transport designed to take you anywhere.
The Segway is fantastic because it can stay upright even though it only has two wheels side by side. Gyroscopes detect when it starts to tilt, the information is fed to a computer that controls the motor that drives the wheels in the right direction and at the right speed, and the scooter keeps its balance. Lots of units take care of safety, so you can enjoy the thrill of speeding up and down hillsides, all under the canopy of beautiful centuries-old ancient trees.
