Registering your bike with the St. Thomas Public Safety department increases the chances your bicycle won't get stolen. And if it does for some reason, it will help in getting your bike back. You only need to register once. It is a FREE service for University of St. Thomas students, faculty and staff.
You can also register with the National Bike Registry for $1.00 per year, or purchase a bike license with the cities of Minneapolis and St. Paul: click on the Links pedal.
