This is what happens when ebike companies take every opportunity to skirt the laws like putting easily removable limiters on motorcycles with pedals and a chain with a gear ratio that makes pedalling practically impossible.

I don't know if there was an existing attempt at regulation in NJ specifically but that's happening all around the country.

The problem is that, while ebikes have a ton of really good use cases, the big market for them is basically kids who want to drive a motorcycle before they're allowed. Ebike companies are going to try to sell to that market any way they can.
