1981 Pro Cruiser

One of the bikes that bridged the gap between BMX bikes and mountain bikes.  The frame design was based on frame that Don Koski fabricated from electrical conduit and a Schwinn Varsity frame.  Mert Lawwill had Terry Knight of Oakland build the frames.  The bikes sold for about $500 new and were made from 1978 though 1982 (approximate run of 600 bikes).  Many of the parts were upgraded on this bike in the couple of years after the bike was made.
