New to eBikes - where to start?

Hey everyone!

Just joined the forum and super excited to finally be an eBike owner! I just picked up an Aventon Pace 500.3 and I'm totally new to this whole world. I'm planning on mostly using it for commuting about 10 miles round trip on paved paths and some light city streets. Any tips for a complete newbie on things like maintenance, accessories, or even just general riding etiquette? What's one thing you wish you knew when you first started out with your Aventon?
