An electric unicycle is a type of transportation that has one wheel and can be powered by electricity. It works like a regular unicycle, but instead of using your feet to pedal it, you use a motor that runs on electric power. The motor is usually powered by a rechargeable battery, so you don't need to buy gas like you would for a car or motorcycle. Electric unicycles can be used for fun or as a form of transportation. They are easy to ride and maneuver, and some models can go up to 25 miles per hour.
