I don't know much yet about how the regulations play out in my local area. I'm just aware of the 3 Class definitions.
If there are going to be regulations for a particular area or trail, I'd personally like those to be by Speed, not what my bike can do.
When I have to ride home from a trail, the power of my bike, and the ability to accelerate, could actually save my life.
I definitely agree people shouldn't be doing 50mph on an eBike. Certainly not on a trail where people are walking.
Someone pointed out lack of panic stop skill. That's a really good point. It's a key lesson in motorcycle safety, but I imagine the typical self taught eBiker hasn't given much thought to practicing a controlled panic stop at a higher speed.
I wouldn't mind having to register eBikes with a simple approach - read safety material online, take a quiz, get a card. Wouldn't want to overcomplicate it, but, some simple way to get everyone to read safety info wouldn't be a bad idea in my opinion.
