The currently state of affairs is that "e-bikes" with more than 750W didn't have a legal classification. They couldn't be treated as motorized bicycles or motorcycles under state law so were it seems they were probably legally limited to private property in Connecticut.
This law seems to expand access as to where these kinds of devices can be legally used, so it doesn't make immediate sense in the context of the article. My best guess for actual relevancy is that it also effectively expands the penalties for using them illegally (i.e. in bike paths or without the appropriate license or insurance) since they now qualify legally as a motor vehicle.
Not a lawyer, just an enthusiast who tries to understand the changing regulatory landscape for my hobby.
