I disagree a little. Yeah, I ride a bike. I also often tech at a bike shop and run a small company that sells fixed gear-related products/parts/accessories. My wife is just as much into bikes as I am (thankfully) and the majority of what I do every single day has to do with bicycles. I would say that might qualify as a "lifestyle" (for lack of a better term).

But - I don't go out of my way in attempt to glorify something that just is.
