In order to deter theft and to help law enforcement match recovered bicycles to their owners, the Mill Valley Police Department offers a bicycle registration service for its community members. The best way to track a stolen bike or to identify the owner of a found bike, is through the bicycle's serial number. Having your bicycle information on file will help us if your bicycle is ever stolen or lost. By participating in the Bicycle Registration Program, you will assist law enforcement in matching recovered bikes to their rightful owners. The program is open to all Mill Valley residents.
