30 - 40 yrs old = Vintage
40 - 60 yrs old = Antique
60 - 80 yrs old = Historic
80+ yrs = Museum piece
It does not matter whether it's a bike, car, or spoons.
It's a generational thing.
It's also flexable as the time gaps often change with different generations.
Some will consider Di-2's, classic, 30 yrs from now.
So yea, you got a Classic.

Interesting! But there are a lot of opinions!
I think there's Old, Vintage, and Classic. Old includes everything past a selected age cutoff, regardless of condition. Any such system should account for stuff that is old but not worth collecting or upgrading. Vintage includes Old, but also stuff that is worth collecting or upgrading. The value judgements should consider history, use by famous people or at famous events, and unique and innovative design and execution. Classic is the same as vintage, but may include post-cutoff or contemporary items sharing those qualities. I don't think it should include items less than 10 years old unless it's a revival of past techniques, design, or technology.
I think catmandew's scale is interesting as a way to establish cutoff points on a timeline.
