Sorry but I don't exactly see what the problem is here...
Are they considered an eyesore? Or is it a problem with parking spaces being taken up?
I think in these economic times we should be sympathetic to people advertising their businesses, be that on signs, in shop windows, on cars, bikes....
I've seen nice bikes with adverts on them in places like Shoreditch and nobody seems to complain about them. Is it because they look pretty?
Also a bit unfair to mention where this guy lives. It's all getting a bit East Dulwich Forum on here[/u] if you ask me...
