New to eBikes - where to start?

Hey everyone!

Just joined the forum and super excited to dive into the eBike world, specifically looking at fat tire models. I live in an area with a lot of sandy trails and some snowy winters, so a fat tire seems like the perfect fit for year-round adventures. For someone completely new, what are the absolute must-knows or key features I should be looking for in a fat tire eBike? Any specific brands or motor types you'd recommend for a beginner who wants to tackle varied terrain?
