I see very few ebikes. I don't think I've ever seen an "illegal" ebike. I've never seen one on in use that goes beyond 20 mph. Until it becomes a real or perceived problem where I live, I think it's appropriate to hold off on any new legislation. I know many of the local police officers and I've talked "ebikes" with many of them. Not one has said that he/she would enforce an ebike laws unless they saw the bicycle (ebike or regular bike) being operated in an extremely unsafe manner that put someone in danger other than the operator. None of them really know what the ebike laws or criteria are so enforcement would be difficult anyway.
I think many of us that post here want us to feel good about being in compliance with ebike laws... but, when it comes right down to it, the general population and law enforcement doesn't care at all. Ride your bikes and ride them safely, you most likely will not have any problems.
