I used to watch the build offs and American Chopper, but I don't much anymore. The thing about American Chopper is that the Tuttles are in it for the money and have been since fairly early on. Note that they had branded an amazing amount of crap -- including playing cards sold at my local Autozone -- after just a couple of seasons. After season two, they moved to building bikes primarily for corporate sponsors, and about that time, we saw the American Chopper Bicycle. I understand there is an American Chopper video game. Last year, I caught their episode about the horror show that became their "production bike."
Now, that doesn't make them good, bad or otherwise, and I respect how they've been able to turn their show into a gold mine. As I see it, American Chopper is entertainment. We're not going to buy their bikes, nor am I going to fork over some cash for American Chopper playing cards. I think their show is entertainment with some bike design thrown in. Some of that design is interesting. Given their massive saturation, I'm surprised they are still as popular as they are.
