I remember when I was in China, electric bike was an absolute necessity. And what made it so easy to use was charging points set up almost all over the city. Even if there was an are that didn’t have charging spots, you could find a shop that was always willing to let us charge for some time.
There were also supercharge spots that where charging for only about 10 mins used to be enough to reach our destination (where of course there would be charging spots!).
