Hi. My first post here – i'm more of a mountainbiker (rigid 1×9 On-One) who became a london fixed-gear and single-speed fakenger 🙂
Unipack/CREATE is not only a cheap/heavy/uncool bike – it's proven dangerous (stems, bolts, cranks, chains failing in full traffic….). We have had a lot of discussions about it here since 2008:

…and many more.
This sums it up: "…the unipack is what it is, a cheaply built bike designed to cash in on the rise of the fixed gear, no one would think about upgrading one of those Apollo full suspension mountain bikes you get for a hundred quid, so why would you want to upgrade the fixed equivalent."
