1976 Super Mirage. VIN 3277973. 602 (February of 1976?) From looking at other postings and my other 3 Motobecane bicycles from 1976 to 1978 that is my guess what the 602 means. 1976 and 1977 frames had similar stampings. Why 1976? According to the Motobecane catalogue, there was no Super Mirage in 1975 and the 1977 Super Mirage was 2040 tubing. This is 1020 tubing which was the 1976 model. Plus the Silver Blue color of the 1976 model did not have the black stripings on the down tube. The 1977 model did. This is a 23 inch frame. Original tires are long gone. Missing wheel reflectors. Rear carrier has been added. Otherwise all is original.
