Hey, Isn't "Fellowship of The Ring" by Stephen R Donaldson?
Its been a while since I've read those sort of books but I always liked them.
"Dune" was a great book but the movie kinda crapped out in comparrison.
BTW, To classify as a moped, Ya couldn't go more than 30mph and it also couldn't have more than 2hp in the propulsion system but, I think that I would be willing to get it registered and insured to be able to ride one.
Maybe some of us will wee our grandchildren riding something like that to school.
