I sent that link to a few of my cycling friends. We had the same questions. Maybe the shop has a reputation of selling really cool bikes. It is kind of a neat idea, though. AND the bikes do look pretty neat with the comics.
If you look at the feedback and check out some of the earlier Pop Art bikes they have had, they mention their process in a couple of earlier sales/descriptions. It really didn't seem too difficult to do the comics like they did. Still, I think it's a neat idea.
Beauty is in the eye of the beholder. I didn't make that up.
