Maybe the frame does, but aside from that I expect it to be a bike of Theseus after a decade. And the original commenter is of course right about the "computerized, electric mopeds" part. That's what makes those bikes useful. The drive unit is likely the expensive part. It also means many parts get a lot more wear because the bikes accelerate faster (= much bigger forces involved) and drive faster on average (= heavier vibrations/bumps). Combine this with accidents (from the bike falling over while stationary, to the rider wiping out, to car crashes) and the useful life of the vehicle is limited.
