I just bought a Rad Power Bikes RadRover Electric Fat Bike. $1674 USD after shipping. I didn't need any crazy range but wanted something a bit nicer than the Sondors bike and had a similar budget to you. I have not yet received it as it is backordered a few weeks, but I hear great things about it.

There are quite a review fairly in depth reviews on YouTube and they seem to be highly thought of. I think.
