I don't have SCI but I am similar to a low level quad. I desperately need to get physical activity back into my life. I have a Theracycle at home, but I think part of my problem making exercise a habit is I get bored with just a stationary bike. We live on a really rough dirt road and the old arm push tricycle I had when I lived near a level bike path is just to hard for me to get up even a small incline. I miss biking terribly. Are there handcycles with gears that would allow someone with less than normal upper body strength to get up the hills on the average bike path? I will probably need to find a used one as I am a working artist and don't make tons of money.
