Seems like a pretty solid kit. For $500 you get a hub motor kit and battery with integrated controller.

They even send you the tools to swap out your cassette.
Anybody try installing one of their kits?
If not, maybe any experience with their hub motor from Aikema or AKM? I think the kit has this one, https://www.aikema.com.cn/en/product/product-54-377.html
