Really interesting, thanks for sharing.
I tried an ebike but went with a poor bike conversion and one that was legal in my country (uk, 250w, max speed 15.5mph). It was under powered for my needs of covering 16 miles of countryside each way to work. Naturally that's my fault but didn't want to venture into illegal even thou I suspect it would have been fine.
I got rid of my car 3yrs back in place of an electric moped-shaped object and have really enjoyed it. 50 mile range, 50mph top speed and it's perfect.
I'll go back to an bike once/if the laws are relaxed
Clearly no exercise at all mind you. I do use an adult push scooter for last mile stuff which works well
