The problem isn't knowing how to work on them. The problem, for shops, is the liability of working on them. Often, replacement parts are hard to find and the brand won't stand behind their product. I'm not sure if Zoomo will be like that or now. Even Aventon, a popular and reputable brand, gave the shop I used to work at issues.
I was in south philly bikes and they were working on someones ebike. I cant speak to what they were working on but the bike owner seemed encouraged that he found someone to do whatever needed to be done.
Depending on the problem Kayuh Bikes in Fish Town might be able to help. I go there a lot and see all manner of bikes being worked on. No idea specifically about Zoomo but their bikes don't appear to be particularly proprietary.
