Obvious to the initiated maybe. When I first tried commuting a few years back with zero prior experience, I was doing so on my 3 speed Schwinn Collegiate until I had a windy day like yesterday and at one point got off the bike and walked because it was faster than riding against the headwind! That was a 14 mile commute and was enough for me to decide bike commuting was not for me. MOST days I'm glad I eventually gave it another chance.
