I'm interested to hear how this goes. I was interested to put a roller drive on a 700c bike. If you are not going to try to ride it like a motorcycle, I expect you could do ok if you are used to a road bike anyway. I think it would be a great ultra-light vehicle, but you might have to stock up on some fat 700c tires, whatever will fit in your frame. Some "touring bikes" from the 80's and these new "hybrid" bikes will take a pretty fat tire, like 700x35. Try some out in the store if possible, or buy $10 ones you can give your friends.
The good thing about this is if it doesn't work well on my "10 speed" I can just move it to another bike, like my wife's.
