A mobility scooter has a seat over three, four or more wheels, sometimes a flat area or foot plates for the feet, and handlebars or a delta-style steering arrangement in front to turn the steerable wheels.
The seat may swivel to allow access when the front is blocked by the handlebars.
Mobility scooters are usually battery powered. A battery or two is stored on board the scooter and is charged via an onboard or separate battery charger unit from standard electric power.
