I'm saying they changed their method of labeling.įrom 1975 to late 1977 the frames have no brake bridge, and had the coaster brake mount welded on. H1D is not an 81 serial number because it doesn't fit the way they numbered their bikes back then, and H is not a plant. What are you talking about, you can clearly identify Mongooses for the first 10 years or more because they did stick to methods of labeling their bikes.

'Hmm, yeah without a pic it's hard to tell mongoose never stuck to one method of labeling their bikes '

I recently bought an '85 Californian on ebay and had it shipped from Florida to my house in Indiana and sure enough it was the same exact one I had sold 3 years earlier! It's amazing how these bikes get passed around. And I keep my old numbers in case I ever see it again. I always keep track of my serial numbers in case they are ever stolen. Hmm, yeah without a pic it's hard to tell mongoose never stuck to one method of labeling their bikes and most times the stickers have been removed so it makes identification really difficult I only know so much about them because I run my own bike repair service and I've owned so many of them.
