I was (and still am) a non-serious roady before I started commuting.

It was kind of a natural progression:
I like to ride my bike on roads,
I commute to work on roads,
I have to work even when I really want to ride,
hence Ride My Bike To Work!

So did you come to commuting from one of the other bike lifes?

And I'm talking primary here, even if you do a mix of riding and one of them takes 50.0001 percent of your time, pick that one.
