My commuter bike with everything weighs in at 55 lbs. The bike itself is not all that heavy. It is a Novarra Randonee road bike but the everything includes: numerous lights, water bottle, rear rack/panniers, pump & repair stuff, full rain gear, work clothes for the day, and finally a backpack with laptop computer. I don't really mind the weight. I could be more organized and drop stuff off at work but I like being self contained. I just have a different riding style when I commute. Obviously it is more like loaded touring than the typical club ride. But I'm loving the commuting.
