My dream in life....well one of them.....believe it or not is simple....a bit expensive but simple. I am disabled and in a wheelchair for anyone that has no idea already. I have a bad back so it is getting harder to get around and would give deep gratitude if I could get a handbike attachment for My chair. They usually run about 1500 bucks is the problem. I think I uploaded a couple pics of basically what I would like something similar to.
