I can hardly count my commute as anything more than a warmup. It takes just 7 minutes, 8 on a bad day. But, when I started riding to work, it was the same time I started riding everywhere else, too.

That being said, I, at 6'1", weighed in the low 200's, probably between 205-215 when I started biking a lot in 2007. After, let's see, a couple years, I had gotten up to 235. That was in Sept-Oct 2009, and it was the highest number I've ever seen on my bathroom scale.

Biking alone obviously wasn't doing it for me. I started doing other workouts and changing how I ate.

I weighed 183 this morning.
