My commute is typically bike one-way (17 miles), multimodal (bike-train-bike, 5 miles on the bike) three days a week. Depending on my work requirements, the weather and my mood, I use the train more.

I use a 2004 Specialized Sirrus comp with racks, panniers, lights and fenders. It's great, and a huge improvement over doing it on a MTB, which I did for years and years.
