the thing is....... downhill must be earned.
I had a bike with motorized rear wheel and that was OK for commuting since I got somewhere less stinky. But that was a long time ago and then there was no real alternative. Today on the other hand there are those e-scooter which a way cheaper that entry level bike and more practical to store out of sight.
I get that with e-bike you can actually do the same and go the same as with bicycle but I really don't see them as the same. That's all.
Not that I mind them in general.
