"Fully faired you will laugh at the wind." There may be laughter involved, but I doubt that's the way it works.
I just crank on through at about 12 mph. Not much alternative on a single speed, though.
Actually, other things being similar, large people should have an advantage in the wind. As you scale things up and down, a person double the size in each direction would have 4 times the frontal area but 8 times the muscle, and should be able to go faster.
