Can anyone recommend an "adaptive bike" for use by a person like me, with MS for 25 years. I use Lofstrand crutches to walk, hold on to surfaces & walls indoors. General weakness and other symptoms = I'd need a lightweight bike so I could push it to park/lock it when done, a place on it to place my crutches(though I was considering somehow putting them in a bag on my back). Big enough wheels so that I could manage bumpy roads, as I have scoliosis and am quite thin. I'd need an electric/battery powered bike that I could cycle on and use the battery as needed. thanks again!
