The present invention relates to an electric scooter. The invention comprises a driving unit formed to perform a rolling motion for each of a front wheel, which is mounted on a base frame to be steered by a handle and first and second rear wheels, which are mounted to be spaced apart from each other in a direction crossing the longitudinal direction of the base frame while being separated from the rear side of the front wheel in the longitudinal direction of the base frame; a steering unit rotating the first and second rear wheels to be steered around the base frame; a mode selecting unit enabling a driver to select a driving support mode while the steering angles of the first and second rear wheels are adjusted; and a control unit controlling a rear wheel steering unit to steer the first and second rear wheels corresponding to the modes selected by the mode selecting unit and, when driving signals are received, controlling the driving unit so that the front wheel and the first and second rear wheels perform the rolling motion corresponding to the driving signals. The electric scooter runs in a narrow space, such as an elevator or a vertically curved narrow path, in a desired direction while the driver is on the scooter and does not need to get off the scooter as the scooter rotates in place and horizontally and diagonally runs with a three-wheel structure.
