Looks like you’re gonna have to be your own e-bike mechanic like me lol. These bikes are pretty simple, they aren’t cars or trucks. Between this forum, and the University of YouTube, you should be able to find a solution to your problems.
I have a 2020 NCM Moscow Plus, and I’ve went from being a dumb drywaller, to an unpaid expert e-mtb technician lol. It’s hard to find timely service this time of year, all the shops what to keep my bike for a week or more, sorry not gonna happen. Anyways, I know how difficult it is to find...
