there is a collector of 1910-1920 cars and bikes, Mike Giddens, who found a 1917 Excelsior in parts in an attic, with only a couple thousand miles on it

He carried each piece down a ladder, then rubbed down every little bit with soap, water and some degreaser to expose the factory army green paint and decals under the decades of dust. The bike had just a couple thousand miles on it when it went into storage long ago. The rubber bits weren't worn, the clutch and brakes had 100% of their material still. A brand new 97 year old bike. It is not on display, he rides it just as Ignatz Schwinn expected him to.
