Have you seen a mobility scooter? It is often referred to as a power-operated scooter or electric scooter. It has a seat over three, four or now five wheels, a flat area or plate for the feet and handlebars in front to turn one, two or three steerable wheels. The seat may swivel to allow a person to get onto it when the front is blocked by the handlebars. The scooter is usually battery powered. A battery or two is stored on board the scooter and is charged by an onboard or separate battery charger unit from standard electric power. Petrol-powered scooters are also available in some countries, though they are rapidly being replaced by electric models.
The handle is the steering column which is centrally located at the front of the scooter. It has controls for forward/reverse directions and speed.The directions can be controlled by thumb paddles, finger controls or a switch.
