I truly don't know if I could ride a single speed. Am I weird because I like shifting and it is one of the most intuitive things in cycling for me? Electronic shifting has eliminated any issues with the derailleur on the bike I ride the most. There are huge climbs around here; not long, but short and steep. I can't imagine doing them on a single speed. Even with the really low gearing, I like preparing by shifting up and down and back up again.
