Xtender Wheels

Xtender Wheels

The Xtender power assist wheels are manufactured and distributed by Sunrise Medical and should be available for compatible Quickie wheelchairs from their dealers in most countries.

What are they?

Xtender wheels are a power assist device that can be ordered on new Quickie wheelchairs or added to existing compatible Quickie wheelchairs to allow users to travel longer distances, climb steeper hills and traverse less than ideal terrains.

In addition to added stamina and power for the user, these wheels also reduce the strain put on the user's wrists, arms and shoulders, enabling them to continue using a manual wheelchair longer before having to upgrade to a conventional power wheelchair and helping reduce the chances of injury.

Xtender types

The Xtender power assist wheels come in two different models.:

• Type A - multiplies the user's strength by 1.5 times and is designed for users who can deliver good propulsion and torque to handrim but want to reduce risk of secondary injuries on upper limbs and wrists.
  • Linear assist feel over various terrain
  • Take-off boost on flat terrain is not significant.
  • Good maneuverability on slope (maximum assist torque is higher than Type B on slopes)


• Type B - multiplies the user's strength by 3 times and is designed for those with limited mobility range who have difficulty delivering enough torque, for example due to C5, C6, C7 spinal cord injuries.
  • Good take-off boost and assist on flat and slight uphill terrain
  • Not suitable for steep slopes (pushrim torque sensor bottoms out, consequently assist power gets flat)

How do they work?

The hand rim of the wheels are attached to switches that send signals to the motors housed in the hubs of the wheels. When the push rims are pushed forward the motors propel the wheelchair forward. When the push rims are pulled back the motors effectively brake the wheelchair or propel it backwards. The movement of the hand rim is minimal (about 1") to go from forward to reverse.

Becoming accustomed to the wheels is quite fast because the user basically uses the standard techniques to propel the chair as they would using conventional wheels.
