As some of you know, I rent a lot of e-bikes. I get to use some of them when they're new, and then ride them again several months or even years later. Some older bikes feel exactly like the first day, but others feel like they have less power. It might be the battery, or the drive itself. Perhaps it's even my own subjective perception.
So I'm curious: do you have the impression that your e-bike has 'faded' over time? And if it has, did changing a component (such as the battery) restore the bike to its original condition?
