New to eBikes - where to start?

Hey Engwe Fam!

Just picked up my first eBike, an Engwe Engine Pro, and I'm super stoked! I've been eyeing these for a while and finally pulled the trigger. As a complete newbie to the eBike world, I'm wondering what are the absolute must-know tips or accessories you'd recommend for someone just starting out? Any advice on maintenance, riding techniques, or cool mods specific to Engwe bikes would be awesome!
