Toecutter is the hero though! Max just finishes the film as a bit of a prick imho, Toecutter and the boys aren't just crazy they're biker crazies. The bikes represent the the flipside of the hippy / freedom association engendered by Easy Rider - the disorder, violence and willingness to do whatever they want. They represent a society about to fall apart and the cynicism the 70s had for the broken dreams of the 60s.
