Legal regulations for eBikes

Hey everyone!

I'm new to the cargo eBike scene – just picked up a RadWagon 4 and absolutely loving it for school runs and grocery hauls around my suburban neighborhood. It's awesome how much I can carry, but it also got me thinking about the legal side of things, especially with the extra weight and size. Are there any specific regulations or classifications for cargo eBikes that differ from regular eBikes in your area, particularly regarding speed limits or motor wattage? I'm curious if anyone has run into issues or has tips on staying compliant.
