It's not just old, it's also rare. Bikes all but died out within a couple of years of cars becoming ubiquitous. Since it was always possible to fit a bike inside a car, there wasn't any incentive to keep manufacturing bikes after you'd tooled up for car production.
bikes, like vinyl LP's, CD's and porn you had to buy, now finds itself at the BSO and retro-poseur ends of the market, but not anywhere in between.
All hail the doom-sayer.
