1979 Lawwill Pro Cruiser. One of the bikes that bridged the gap between BMX bikes and mountain bikes. The frame design was based on a 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 1979 though 1980 (approximate run of 600 bikes). Text courtesy of the Museum of Mountain Bike Art and Technology.
