I have been a respected member of since just after its inception. I raced competitively until a bad crash a few years ago taught me the tough lessons of being old and healing time. I've seen and owned a LOT of great bikes. You want to own one of the rarest BMX bikes in the world? Here is a 1980 CW-Z, the very first model CW ever made with the legendary oval top tube, aka-the ball buster, lol, and this one is VERY early, if not a prototype once the switch from brass to chrome (hence no serial number).I have spoke to several BMX historians (and I am somewhat of one myself) and they all agree that this is a RARE one.
