An electric scooter is disclosed that has a propulsion system switchable between two modes, one of which allows a higher maximum speed than the other. The mode is selected by a user operated button so constructed that the high-speed mode is selected only while the user continues to operate the switch. A steering angle sensor and a tilt switch are provided, which prevent the user from selecting the high-speed mode while steering sharply or while going down or across steep slopes.
