No idea but I don't go round anything in the Black Forest. Straight up normally. Steep enough for most people.
And you are right. I take no satisfaction getting up steep climbs like I do on motorbikes . I only go up to go down. That's part of the reason for buying one. If you get a bigger buzz out of shagging yourself out for an hour going up followed by five minutes of going down, then you don't need an e-bike.
You misunderstand. It's about the joy that comes from exercise and fitness as well as the pleasure of actually riding a bike.
