Register your Brompton for an extended 7-year frame warranty

Registration is a quick and easy way to protect your bike and investment. It provides a record of your serial number in case your bike is ever lost or stolen, and will help us get in touch with you with important product information.

You can register old and new Brompton bikes to take advantage of our extended 7-year frame warranty and a 3-year electrical system warranty on Brompton Electric bikes.


Find your 10-digit frame serial number

For bikes made pre-2016, the frame serial number is on a silver sticker near your seat clamp.

For bikes made in or after 2016, the frame serial number is on a plaque by your bottom bracket.

After entering your 10-digit frame serial number in the box below, you will need to create an account or login to continue with the registration process.
