A gyro scooter is a two-wheeled scooter, a street electric vehicle made in the form of two connected transverse foot pads, movable relative to each other, with wheels on the sides. Uses electric motors powered by an electroaccumulator and a series of gyro sensors to self-balance and maintain the horizontal position of the footrest.
