The main aim of a four wheel mobility scooter is to give people a richer quality of life and give them the freedom of choice that a wheelchair does not afford.
4 wheel mobility scooters give people independence and allows them to manage a lot of the everyday tasks themselves, such as shopping, going out with friends, going out for "walks" with people, they no longer are housebound.
4 wheel scooters are the most reliable when it comes to outdoor use.
If you are certain that the turning radius of the larger scooter will not affect your mobility, especially indoors, then a full-size 4 wheel scooter is a good choice, though some 4 wheel electric scooters have a hybrid design that places the front wheels close together giving users a good mix of stability and maneuverability.
Many 4 wheel model mobility scooters include front and rear suspension to provide a much smoother ride at higher speeds than 3 wheel scooters.
Four wheel scooters are designed for maximum stability, and are mainly intended for outdoor use. They are only slightly less maneuverable than the 3 wheel, yet most four wheel mobility scooters do maintain a turning radius that allows you to perform daily functions inside your home. Some of the larger models have knobby tires and high ground clearance which make them great choices for use off road and in rugged terrain.

Mobility scooters come in various types: · small, light scooters for travel, which fold or are easily disassembled into smaller parts for transport; · large, heavy scooters for rough outdoor terrain; · mid-range scooters, which are intended for both indoor and outdoor use. Usually mid-range mobility scooters have a speed of about 5 to 7 mph (8 to 11 km/h).
