Legal regulations for eBikes

Hey Engwe fam!

I've been loving my Engwe Engine Pro for my daily commute and weekend trail rides, but it got me thinking about something important: the legal side of things. With so many different classes and power levels, it seems like the rules for eBikes can vary wildly from state to state, or even country to country. What are your experiences navigating the legal regulations for your Engwe? Have any of you run into issues, or found particularly clear resources for understanding where you can and can't ride, especially with our higher-powered models?

Cheers!
