The Models page has been revised and updated to include previously unlisted bicycles. The titanium Bertin C 75 T and the welded aluminum C 80 Dural are interesting curiosities. The list does not include children’s or juveniles’ bikes nor the BMX and Duralinox line of Vitus cycles. It does, however, show illustrations of the Bertin small wheel and folding bicycles. You may access the revisions from the tab at the top of the page or click here.
