I just built up a Cowan a few months ago. It's geared right now, but I'd like to make it single speed. Maybe I'll pick up one of those conversion kits for a standard hub. Anyway, It's a sweet bike. I use it for park, street and some dj. No complaints so far. The bike has held up like a champ. I've made a few changes since, but here's a pic from when I first built it up.
