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 get riding! I'm completely new to the eBike world and feeling a bit overwhelmed with all the accessories, riding tips, and maintenance info out there. For those of you who've been riding your Lectrics for a while, what's one piece of advice you wish you knew when you first started? Any must-have accessories for city commuting or light trail riding, or things to avoid? Thanks in advance for any wisdom!
