Im a fan of Lectric ebikes. They pack a lot of features and quality into a rock bottom price, and seem to be in a good position as a company, so no sudden bankruptcy leaving you stranded like some brands recently.
I bought one of their ebikes, and was impressed at the overall quality. They do tend to use "generic" or "in house" bike components to likely save on spend, but nothing seems shoddy. My bike has a 750w motor and is a class 3, so it can and does hit 28mph smoothly and easily and has a 20-40 mile real world range.
I did have an issue with a leaky hydraulic brake line after storing it for a few months. I reached out to them about it, and they instantly mailed me a replacement brake and lever for free. That was nice, but as a counter point their "break replacement" video was for an entirely different model and was only about 70% applicable.
Some give and take to be sure, but I'm glad to have the bike and would buy again.
