I won this cool looking bike in a drawing from a local watering hole, and know absolutely nothing about single speed bikes. It looks like it has a flip-flop hub, which I will have to research to figure out how all that works, too. I haven't seen anything like it, but it looks like it would be fun to ride, although I am not fond of a front brake only bike. The handlebars are crazy short at 18 inches as well, which means they will have to get changed out as that is way too short. Either way, once I go through it all it should make a fun grocery getter or something...
