That's sweet.. I've been looking at a Fastback, too. I'm wondering what y'all think about Fastbacks vs. standard StingRays as adult riders... I'm not a light guy, so I'm thinking the bigger wheels/higher tire pressure of the Fastback would be the way to go. Any thoughts? I rode with a group of guys last week, and everyone (11 guys) had some kind of a StingRay but me, and I wanted in on the fun!
