I remember all my bikes, but then I have only had nine, 4 of which I still own, and 3 of which have been purchased within the last 8 years. Of those, four were new; the 3 speed Royce Union I got for my 11th birthday, the 10 speed Bianchi I got for a college graduation present, the 10 speed VeloSolex I bought myself 3 years later (and sold the Bianchi to my roommate), and the Lemond Zurich I bought in 2006.
