No matter how I look at it, I think I need two bikes. Looks like you're in the same position.

Nice bike for social just-because rides; and a beater I can let out of my sight without having a heart attack. I have a beater now - commuting to work every day on a $160 bike that's 30 years old. Works fine and it's not worth the effort of busting a U-lock to steal. It's stupid to say you can't commute anymore, there are solutions.
