I don't get why he repeatedly throws in that it might be better for the cyclist to lose weight than it would be for the bike to lose weight. That wasn't part of his experiment. In fact, the heavier bike was slightly faster, so if he wanted to extend that to some "heavier is better" conclusion, he'd have a better basis to speculate that it would be better for the cyclist to gain weight. He's got no data to indicate that rider weight has anything to do with commute speed. I suspect it might, but he didn't test for it.
