Sgt Owen Messenger, roads policing officer for Devon & Cornwall Police, said running the operations was important “to educate and deter their unsafe and illegal use”.
“Our focus remains on keeping all riders, road users and other members of the public safe,” he said.
The force said it would be carrying out similar activities “into the New Year and beyond”.
It said it spoke with 19 riders during the operation, which was led by the Roads Policing team and supported by the Drone Unit and Falmouth Neighbourhood team.
Sgt Messenger added: “If you’re looking at buying or gifting an e-scooter or e-bike over the festive season, please make sure know the laws and stick to them.
“If you don’t, you could run the risk of it being seized and destroyed.”
