Strictly speaking, my Nishiki Landau is not a "vintage" bike, since nothing but the frame survives from the original stock machine ... and it's been that way since the first year of its existence--1978.
I've owned my Landau since 1979. It was my one love for more than a decade and I still take it out on dates.
It also serves now as my "camera dolly" of choice when I'm making videos.
I created a bit of a history about my old flame on VeloWeb.
Lovely machine
