To the OP: The page you linked to won't load.

I honestly don't understand why there needs to be a "commuter bike" nitch in the first place. Maybe I just don't get it... but commuters are already well served by the likes of Surly, Jamis, and Bianchi, to name a few, and the bikes from these companies are not marketed specifically as "commuter" bikes. The Breezer series are marketed as "commuter" bikes but, long before Breezer hit the marketplace, bikes like them were around and were called "comfort bikes". I think that manufacturers are just looking for another marketing category so that they can sell more stuff.
