The Servo

Bridging the Gap Between Manual and Automatic Wheelchairs

Starting at $8275

The Servo power-assist system makes it possible for wheelchair users — even with reduced strength — to move independently and increase the distance they can travel.

The Servo uses technology that mimics the effect of power steering in a car – it augments the user’s strength when pushing the wheel rims! Using the servo is just like using a wheelchair. Just easier.

That means you can maintain a healthy level of activity while reducing the strain on your muscles and joints.

The Servo gives you the control of a manual wheelchair with the added mobility and freedom of movement that comes with a traditional electric wheelchair.

DETAILS

Advantages over manual (unpowered) wheelchairs:

  • Much easier to self-propel over challenging surfaces such as thick carpets, rugs, and door transitions.
  • Easier and safer to travel both uphill and downhill.
  • Ability to independently travel longer distances without getting tired.

Advantages over traditionally powered wheelchairs:

  • Easier to control with reduced fine motor skills.
  • Adjustable degrees of assistance to maintain a healthy level of activity.
  • Decreased potential to injure yourself or others
  • Lighter and easier to disassemble for transport
