A brake device has a cam and a switch. The cam is securely attached to the steering bar of the electric scooter. The cam has a circular periphery with a plain portion and a notch. The switch is secured to the body of the electric scooter and is electrically connected to the actuator. The switch has an arm with a distal end abutting either the plain portion or the notch according to whether the scooter is turning or traveling straight. With such a brake device, the scooter will be automatically slowed down when the scooter is turned right or left.
