Register your bike using the Bike Registration Form.
After you complete this form, a bicycle registration sticker will be mailed to your campus address or home address. There is no fee for this service. Registering your bike helps to recover it should your bike become lost or stolen. Questions about bicycle registration should be directed towards MIT Parking & Transportation, firstname.lastname@example.org
If your bike is missing from campus call the MIT Police at (617) 253-1212. If your bike is stolen off campus contact the police in that city.
