Three Most Common Types of Electric Wheelchairs

The Electric wheelchairs, also called Power Wheelchairs, are often a more suitable option for those who are physically unable to self propel a manual wheelchair. Before purchasing an electric wheelchair be sure to consult with an occupational or physical therapist. Electric Wheelchairs are available in a wide variety of seat widths, depths and heights, and feature a number of armrest, legrest and seating options. Power wheelchairs allow users of every strength to control the electric wheelchair with a joystick, but higher end models offer a multitude of alternative control options such as proximity switches, sip-n-puff, head arrays, infrared switches and magnetic angle sensors just to name a few.

The Three most common types of electric wheelchairs are front wheel drive, mid-wheel drive and rear-wheel drive.

Front wheel Drive for Power Wheelchair:
Feature six wheels, including two rear anti tip wheels because they turn from the center like a top, they are considered the most maneuverable power wheelchair, even in tight spaces. The power base is usually separate from the seat and will accept any number of seating or power seating options, depending on wheelchair features.

  • Front drive wheels are placed forward of where you sit
  • very stable for uneven terrain or up and down hills
  • climbs over small obstacles well
  • slower overall speeds (about 5 - 5 ½ mph) because front wheel drive tends to "fish tail" at higher speeds

 Your center of gravity is about even with the center of the drive wheel in a mid wheel drive chair, so the drive wheels essentially are under the user. You end up with equal parts of the chair in front of and behind your body. This type of chair is maneuverable in small spaces, with a turning radius of 24 to 26", depending on the manufacturer. Overall speeds are limited to about 5 ½ mph. Another consideration is terrain. When riding on uneven terrain or up and down curb cuts with a steep transition, there is a possibility of getting "stuck" on the front or rear casters, suspending the drive wheels so they have no contact with the ground.
