When selecting a base for a complex rehab power wheelchair, the drive wheel configuration is a key consideration. Rear‑wheel drive offers many benefits, especially for outdoor and more demanding terrain.
What is rear‑wheel drive?
In a rear‑wheel drive configuration the two large drive wheels are positioned at the back of the base, with two casters at the front. The placement of the drive wheels provides the source of the wheelchair’s propulsion power.
Key advantages
-
Extra power: A rear‑wheel drive power wheelchair can perform better on more aggressive outdoor terrain and push forward through softer surfaces.
-
Stability and ride comfort: These models typically include independent suspension or shock absorbers on all wheels, which helps deliver a smoother ride experience on uneven ground.
-
Better control: The turning speed of the chair is slower in a rear‑wheel drive configuration, giving the user more time to adjust their joystick and complete turns safely.
-
Large drive area: With the weight of the chair focused where the drive wheels are located and a larger base, the stability is enhanced under many conditions.
When it is a good choice
If you spend a lot of time outdoors, encounter uneven terrain, soft ground or slopes, or require a chair with strong stability and traction, a rear‑wheel drive power wheelchair may be the right fit. It is also beneficial where ride comfort on challenging surfaces is important.
Key takeaway
A rear‑wheel drive power wheelchair provides strong performance, enhanced stability and improved control making it an excellent choice for users with outdoor mobility needs and those navigating more demanding surfaces. Working with your therapist and ATP to match this configuration to your lifestyle and environment ensures you get the best possible support.
