Unipack / Create / Sports Direct singlespeed track bikes?

... they are purely fashion items. its like fake ralph lauren, from a distance it looks alright but then the label says "rolph laverne" and the logo is someone riding a cow. the stitching will fuck up, it wont fit properly and will be terribly made.

do you know anywhere in London where I might be able to try on / purchase one of these Rolph Laverne shirts?
