That's awsome! I built one 4 years ago to ride to work in the winter, 7 blocks and I beat guys that live near me there! :lol: I've heard a lot of people say I outta put an engine on it, but I'm 6'3" and my hammerhead is a bit top heavy. Turning has to be slow or leaned into. Do you have the same issue and are you only using one caliper brake on the rear? I had to add a second on the back, since mine clocks in at 50lbs! Cool to see other Atomic Zombie fans too!
