85% art 10% usable bike 5% I got one and you don't.
I think the interesting angle is, unlike a rare gas bike or car that just sits and is hardly used and goes up in value, those batteries will die used or not.
I mean in 15 years if left in it's "original" form it will be unusable. I'm sure you could replace them with much better technology at that time but then it's no longer original.
