I have an ´04 Big Buzz which I have been commuting on. I like the bike but have had some issues. Like other people, I have had problems with the wheels, specifically, breaking spokes on the rear. A friend of mine worked at the bike repair shop in the flagship REI store in Seattle and admitted that the Big Buzz wheels were notorious for spoke problems. Also, the M425 rear hubs which are widely used on OEM wheels are famous for blowing out freehubs, and mine went out twice with less than 1000 miles each time. The freehub is easy and cheap to replace, but I finally gave up on the wheelset and built my own with XT hubs, Alex Adventurer rims, and DT Competition spokes. I also had the ISIS bottom bracket fail at about 5000 miles, and the replacement is now failing with about the same mileage on it. I will not use an ISIS crank again.
