The Wheeltech Powerstroll Wheelchair Powerpack makes pushing a wheelchair easy, and will turn most manual wheelchairs into a carer controlled electric wheelchair. Once fitted, it helps to make light work of hills, ramps and uneven surfaces. It is very versatile and can easily be transferred between wheelchairs, or removed, in seconds. The sensitive finger control makes it very easy to use. A variable speed control and attendant controlled brake system are available as optional extras.
