Yeah, the metric used (energy output) is a strange way to decide if e-bikes are “worth it” compared to an analogue bike.
Some people will never touch a regular bike, for one reason or another. But they’ll happily get on their e-bike at any chance they get.
If an e-bike motivates someone to not drive, or to be more active, or to explore their community, or to improve their mental health… or all of the above… then, hell yeah, it’s worth it!
