A Segway is a two-wheeled, self-balancing personal transportation device. It uses sensors and gyroscopes to help riders maintain their balance while standing on a platform. To move, riders simply lean forward to go faster or lean back to slow down or stop. This makes it easy and fun to navigate through city streets or parks. Originally introduced in 2001, the Segway was designed to revolutionize personal transport. While it gained popularity for tours and short commutes, it faced competition from other devices like electric scooters and bicycles. Today, Segways are often used in guided tours and by security personnel in large areas.
