Thanks, that's a lot of help. So I know how to be a hipster now and how not to be (because 5 minutes ago i didn't know what that meant). As we often are here in Ireland, I think we might be a couple of years behind in this trend. Right now fixie bikes like the yellow and blue one pictured above are popular among the kids that wear thick framed glasses with no lenses and work in 'new aged media'! I am not one of those people, I'm just trying to suss out how uncool this trend actually is?
