Basically, electric wheelchairs are chairs that are mounted on wheels. By moving the wheels, the chair can be moved from one place to the other. Hence, the electric wheelchairs are a substitute for the natural mobility of locomotion impaired people and those people who cannot walk because they are recuperating from an illness, or are sick. Also, people who are obese or old might experience difficulties in walking. Electric wheelchairs could be a good solution for them. Electric wheelchairs can be operated either manually or mechanically.
