I work at a campsite in Sweden. Yesterday a couple of fully loaded tourers rolled in with e-bikes. Never seen that before, although I do see more and e-bike commuters.
Here they are allowed to go at max 25kmh on the same paths and MUPs as regular bikes, though some have obviously been modded.

It wouldn't surprise me if the number of e-bike tourers increase as the batteries get lighter and can go for longer distances between charging.

I'll definitely consider an e-bike if and when I get too old and frail for a regular bike. Hopefully by then the battery will be a retro fit internally to any bike, weigh next to nothing and be charged by the solar painted frame

Thoughts?
