1972 Columbia Tourist Expert III, Columbia Roadster
Regardless of whether his vehicle was technically a moped or a motorized bicycle, he was travelling faster than the allowed speed. He should be ticketed for that.
The laws regarding what is considered a moped vary from state to state, there is not national uniformity - so it's not ever worth getting into the discussion of what a motorized bike is compared to a moped compared to a scooter compared to a motorcycle, you'd get over 50 completely different answers that are all right in their own state, but completely wrong anywhere else.

Agreed they should be ticketed if speeding. I do think it interesting that quite often human powered cyclists travel over 20mph in the BL.
