Technology is developing rapidly and there have been many interesting transport inventions. Here are some of them.The Ryno is a one-wheeled electric motorcycle. Just shift your body weight forward to go forward or lean back to stop or slow down. There's also a hand brake. You can ride it anywhere and with just a little bit of practice, nearly anybody can ride it. In my opinion, it's a convenient, environment-friendly vehicle. Hovertrax is the world's first portable, double-wheeled, self-balancing electric scooter. It's controlled by shifting the body weight. Stand on the foot platform and lean forward to move forward. Lean back to stop or move backward. Shift more weight to one foot to turn. One problem is that it can be only used on a smooth surface. Personally, I think when using it, there is risk of injury, especially for children. Which invention do you prefer to use in the future? I'm sure it will be very interesting to try one of them.
