V_TWIN sounds like a Karen.
Driving an unregistered bicycle that may be a moped, sounds like the cop was confused since the boys house was 300 feet away the prudent thing would be a citation and a call to city attorney for clarification of Florida law in low power electric bicycles. If it has pedals and less than a HP it is a power assisted bicycle in my book, over a HP a moped. Over 5 a motorcycle...really simple. 50 years ago the cop would have been named and shamed locally, like a health inspector shutting down a little girls lemonade stand.
RIF. It's not the cop who's confused about the law. It's you.
A 'bicycle' has pedals. A 'moped' has pedals. An 'e-bicycle' has pedals.
The kid was riding an 'e-motorcycle' that did not have pedals. It also didn't have lights, registration, insurance.
Nor, did the 11 y-o have a driver license with a motorcycle endorsement.
