Legal regulations for eBikes

Hey everyone!

Been hitting the trails a lot lately on my full-suspension eMTB, usually doing 20-30 mile loops in the local mountains. It got me thinking about all the different rules out there for eBikes, especially when it comes to Class 1, 2, and 3 classifications and where we're actually allowed to ride. What's the situation like in your area for eMTBs on singletrack and multi-use trails? Are you finding it's generally accepted, or are there still a lot of restrictions and confusion?
