For whatever reason people abandon all logic or sense when it comes to ebikes. My city's shared pathways have a posted speed limit in many areas. Just because you can do 45km/h doesn't mean you must.
Hell, on multi use paths I tend to practice my slow speed stability drills whilst navigating through dogs, children, strollers, quail and the occasional snake. I only drag race ATVs on jeep trails.
If someone is doing 45kph in a 30kph posted bike path they should get a ticket. That's pretty straightforward.
I wish more bike paths would be like this. I really dislike when they do stuff like "this path is Class I only" as if anybody, cops included, has any idea what that means.
I would also make it apply to pedal bikes. If someone's pumping the pedals real hard and doing 35kph in a 25kph zone that's also a ticket.
Slightly derailing the thread, yeah, we need speed limits and cops on scooters. Of course, we won't get any enforcement in the vast majority of places because the US doesn't do that. Aircraft carriers don't build themselves....
The class II setup on this bike is interesting. Of course, this is clearly NOT a mountain bike but you could ride it on some MTB adjacent trails. In my neck of the woods, class II bikes are limited to the same places as motorcycles. The very occasional BLM enforcement includes checking for a throttle. If it has one, it's a motorcycle. But that has really little relevance for this particular bike.
