I've been commuting on a Big Buzz since March last year. I've really enjoyed it to date, though I've also had some issues with blowing spokes on the rear tire. Some of this is probably my fault - my previous route had me going down/up a curb with a loaded pannier once each way. (I've replaced a couple spokes since I switched routes, but I suspect the original damage was done prior to the route change.) Anyway, my father in law helped me replace the spokes with some reported to be better quality, and I haven't had any problems since.
