The bikes are in good condition, Deputy Chief Andy Jackson said, and have been reported abandoned by people who call to report seeing them.
Thus far none have been matched in records the police department keeps on bikes reported stolen, he said.
If the bikes are not claimed they will be donated to local charities.
Persons who can prove ownership must contact the police department at 252-533-2810/ 2811 to submit a claim.
