Assistive and small sit-down electric mobility scooters provide important advantages to people with mobility problems throughout the world. A scooter is useful for persons without the stamina or arm/shoulder flexibility necessary to use a manual wheelchair. Also, swiveling the seat of an electric scooter is generally easier than moving the foot supports on most conventional wheelchairs. A mobility scooter is very helpful for persons with systemic or whole-body disabling conditions (coronary or lung issues, some forms of arthritis, obesity, etc.) who are still able to stand and walk a few steps, sit upright without torso support, and control the steering tiller.
