I'm not certain, but perhaps your referencing moped law... Isn't there a difference between moped laws and bicycles that do not fall under moped laws? To my novice understanding, they are bicycles that only go 20mph max on engine power alone and have engine displacement limitation like 49-50cc or less.

If your ride is within those specs, seems like moped laws don't apply to power assisted bikes, because it's not a moped as defined by the law.
