I think what he means is he thought our bikes did not require registration and plates or drivers license to be street legal in the State of California.
If he was in my state he would be correct, but not in California.
The 30 mph may be correct but I know it can be larger than 50cc in California. Where's that @Wrench when you need him? I know an electric up to 750w and a 20 mph speed limit doesn't require a license, registration, or insurance.
