The Powerpack attaches to any wheelchair in literally seconds. Once fitted you will never need to push the chair again. With speeds up to 4mph and a range of up to 10 miles there is more than enough capacity for most days out.
The standard single wheel version is capable of transporting up to 18 stone user weight. The twin wheel model has the same user weight limit but gives much greater traction - really effective on loose gravel and wet grass.
