The redesigned scooter allows the rider to steer by leaning to the right or left, rather than by turning the handlebars. It also features a wireless electric key and alarm system.
The scooters feature two side-by-side wheels, and are ridden in a standing position, with the rider grasping handlebars. A gyroscope provides balance, making it fairly easy to remain in the upright position.
Officials at Bedford, New Hampshire,-based Segway Inc. said they have sold tens of thousands of the scooters since they were unveiled with great fanfare in 2002.
The scooters have been adopted by some police and security services in the United States and abroad, but remain an uncommon sight on American streets.
