I know they're an entry-level/mid range fixed gear bike that is all black and comes complete with mismatching rims/tires...pretty sure it's a white rim w/ black tire in front and a black rim w/ white tire in front. What bike is that?

I'm not thinking of getting one or anything, but I saw a dude riding one last night and it's just been one of those things where I'm struggling to recall what bike it is.

While typing this, my wife just said maybe I think about bikes too much.
