Having a registered serial number gives you the best chance of recovering a stolen bicycle. These numbers are used by cops all over the country.
Where to Find it
The majority of serial numbers can be found beneath the bottom bracket, where the two pedal cranks come together. Turn your bike upside down and write down the serial number.
