Found a couple of these on Craigslist. Ad says he'd take $1200 for both of them, but before I even ask about them I wanted to try and find some info on these and am not having much luck.

 

My buddy has one and is on his 3rd kid, needs a rear chain now but has otherwise been solid. If you want more then 15 mph out of them you have to remove a spacer from the clutch. Has nice big tires and gets round good.
