Ok, so I read often how bike travelers like ride with a tail wind and that it helps a lot, especially if thebike is bulky.
Well, wind makes it a little easier to pedal. So, why not make a big sail, that will push the bike fast without even need to pedal, or maybe will significantly help pedaling up the hill.
If they say, tail wind blows approximately 25% of the time, it could be a noticable help.
What do you think?
