Sorry to be a stickler on this but (a pet peeve) I won't likely ever be a road "biker." "Bikers" hang out in biker bars, have "bike" rallies, and hold an annual event in Sturgis. That's not my thing.

More to the point (perhaps) is that all groups or distinctive activities have their own traits and foibles, and it's not difficult to find the humor in that. This is hardly the first effort to lampoon people who ride road bikes.
