New to eBikes - where to start?

Hey everyone!

Just got my first eBike – a Class 1 commuter style, and I'm super excited to hit some local paved trails and maybe even some light gravel paths. As a newbie, I'm thinking a lot about safety, especially with the added speed and weight. What are your absolute must-have safety accessories or tips for someone just starting out, beyond the obvious helmet? I'm particularly interested in things that help with visibility or emergency situations.
