New to eBikes - where to start?

Hey everyone!

Just picked up my first eBike, a Lectric XP 3.0, and I'm super excited to join the community! I've been riding traditional bikes for years, mostly on paved trails and some light gravel, but the assist is a game-changer. My question for all you seasoned Lectric owners is: what are your absolute must-have accessories or first upgrades for a new rider? I'm thinking about things like comfort, safety, or just making the ride more enjoyable. Thanks in advance for any tips!
