Townies are pretty damn sexy bikes. If your commute is pretty flat, it should be great. I wish my commute was less like a rollarcoaster, I'd be rocking a townie too.

I'll echo others here in starting off easy. When I first started commuting(around 26 miles round trip), I rode to work and got a friend to drive me home. I'd drive in the next day and if the weather was good and I was feeling good, I'd ride my bike home. I did several one way trips in this fashion for 2 weeks and I'm pretty much riding to and from work 4 days a week now(1 month later). I can't get enough now.
