1st gen. gusset by the bottom bracket, a coaster tab but no brake bridge. (Sept'75-Jan'77)
Serial Numbers
(located on the underside of hanger cup/bottom bracket shell):
1975 serial numbers were a hand-stamped five number, individual frame ID. They begin at 10001 and continue until early 1976 when a revised stamp begins to include place of manufacture indicated with the letter 'C' ( for Chatsworth, California) followed by the five number individual frame ID. It then changes again later into 1976 to include place of manufacture/month/year code followed by a five number individual frame ID. Example: CB6 ##### (C=Chatsworth B=February 6=1976). After February 1977, (CB7) the second generation frames appear without the extra gusset between down tube and seat post tube.
2nd gen. removed BB gusset and added brake bridge. (Feb'77-June'79)
3rd gen. removed coaster tab. (July'79-June'81)
4th gen. step down, 2-hole dropouts were added. July '81

PATTERSON BMX has 1,309 members. Dedicated to all things Patterson BMX. Buy and Sell Group. I have been interested in trying to figure out the key to the serial numbers on early and later Patterson Frames. I'd like to compile all serial number for known bikes on this forum. You can put an X as the last digit if that's preferred. I'd like to know the year, month, model and complete serial or with an x as the last digit. Patterson Pr 200 bmx, used. Patterson PR 200 serial no 2840668owned since patterson bmx pad set repo in yellow used good con. 'If the purchased item you have received is defective, please contact us, we would settle it'.
