That's not a Langster, that USED to be a Langster, but the brakes have been removed and bullhorns put on. Now it's just a fixed gear conversion... not that there's anything wrong with that.

Langsters aren't "cool" around here, BTW. It's not "cool" to buy an inexpensive, ready-made and hassle-free single speed bike. Better to do a search for "cool" bikes and buy one of those. And make sure it's fixed cus everyone knows that fixed is the "cool" thing! Just like our ebay friend here.
