New to eBikes - where to start?

Hey everyone!

Just picked up my first eBike – a RadRover 6 Plus, super excited! I'm planning on using it for my 10-mile commute on mostly paved paths, but also some light gravel trails on weekends. As a newbie, I'm a bit overwhelmed with all the safety gear out there. Beyond the obvious helmet, what are some must-have safety accessories or practices you seasoned eBike riders swear by, especially for urban and mixed-terrain riding? Any tips for a beginner on staying safe out there?
