What do you use to get around town? A car? A bike? Your feet ? perhaps you should try a segway!
The Segway is perfect for short journeys. It’s an electric vehicle that consists of a platform between two wheels, with a pole that connects the platform to the handlebars. To ride it , you step up onto the platform, and control the Segway by moving your body. Lean forwards to go faster, and back-wards to slow down.
On older models, direction was controlled by a twist grip（扭转把手）on the left handlebar. This varies the speeds between the two motors, and a decrease in the speed of the left wheel would turn the Segway to the left . With newer models you simply lean to the left or right. Meanwhile, a gyroscope （陀螺仪）detects your movements and prevents the machine from falling over. The Segway has a maximum speed of 19 km per hour and a range of about 38 km. after that, you need to plug it and recharge the battery.
Segways are used for a variety of purposes. People with mobility problems can now enjoy walks in the country with their friends and family. Some golfers see them as an alternative to the golf cart . And dog owners now have an easier way to take the dog to the park. A few police forces use Segways, too. They allow officers to move quickly while maintaining contact with the public. They’re also becoming a common sight on airport . However, the most popular use is in tourism , particularly for city tours . Visit any major tourist city in summer, sit outside a cafe for a while and there’s a good chance you’ll see a group of tourists passing on Segways.
