Ah, well the difference is that modern bicycles are ridden quite a bit differently than your good ol' 65 pound cruisers from Sears, Wards, and even the Schwinn phantom. Those were neighborhood crawlers that kids mostly walked up hill. A modern bicycle weighs anywhere from the neighborhood of 1/3 of that for mountain bikes, to 1/4 of that for road bikes. The speed and manner that bicycles are ridden have increased dramatically. The result is a lot more stress on the equipment and risk to the rider. It's not the same world anymore.

I had a three speed Schwinn, I walked up certain hills.
