New to eBikes - where to start?

Subject: New to eBikes - Just ordered an Aventon Soltera! Where do I even begin?

Hey everyone! Super excited to finally join the eBike world. I just ordered an Aventon Soltera.2 and I'm eagerly awaiting its arrival. I'm planning to use it for city commutes (about 5-7 miles each way) and some light weekend trail riding, but I'm completely new to all of this. What are the absolute must-have accessories or first steps you'd recommend for a total beginner? Any tips for a new Soltera owner would be amazing!
