I am a 34 year post injury C-7 incomplete Quad, until SoftWheel I used and pushed many different types of wheels however, none of them have offered the ride quality or comfort provided by the SoftWheel.
At first I was concerned about the increase in weight but, after pushing the wheel I noticed that the little bit of extra weight was not a factor. The mechanism of the wheel actually helped me to propel up the hills and city streets. It was the most amazing sensation to actually feel the wheels release energy back that I normally loose.
While traversing streets in Seattle recently I encountered a curb and simply popped up my front casters hit it straight on and felt the energy release again as it help me climb the face of the curb. Again, after 34 years of pushing a wheelchair this is the first time my wheels actually helped me up the curb.
Needless to say that everyday travel in my chair is quite comfortable without having the day to day vibrations of rough surfaces radiate up through my back and neck.
My next venture with the SoftWheels is to mount a lager diameter "off road" tire on them and go for a long push on the 4x4 trails behind my home. I have no doubt that the ride will be smooth.
