My bike with all the hardware and personal item weigh in right at 40 lbs. That's about as reasonable as it gets for me especially when I have to carry my bike up the stair at the train station if the elevator is out of service. It gets much heavier when I do some grocerie shopping before going home. I easily have a 50+ lb bike under me. Needless to say, when it is at that weight, I don't need to climb anymore stair.

I had guys picked up my bike just to see how much stuff I am carrying and some just about get an hernia while other will say "Not too bad". I often wonder who is really telling the truth?
