Sweet!

Track bikes are neat. Looks like yours has fairly generous tire clearance. And front and rear brakes!

Some advice I've seen on here before - the first time you ride it, set up your saddle 1/2"-3/4" lower than you normally would want it.

This will give you some room to move around when you forget you're on a fixed gear and try to coast. It will give you a fighting chance when the bike tries to buck you off
