We have a couple of these at my shop. At first glance, the rear hub looks like a dual freewheel. I haven't really checked to see if they installed the freewheel on the fixed side, but it doesn't look that way. Doesn't make sense considering the marketing we've seen. On top of that, the rear brake is clearly meant to be cleanly removed, with the cable housing essentially zip-tied to the the frame as mentioned before. Maybe it's all just a quirk of assembly.

Other than that, it looks like a neat bike...nothing interesting about the spec, but I like the subdued look of the frame.
