Great Bike!

I've had the bike for almost 6 months. I had to custom make a rear kickstand, install pedals (it doesn't come with any), and grease the rear shock which had been installed dry. That said, I'm enjoying this bike immensely. It's fun to ride, both on the street and on the trails, it looks good, and it has a general solid high quality feel to it.
