How do I find my frame and serial number?

Each Brompton leaves the factory with two numbers that uniquely identify your bicycle. These are the serial number and frame number.


For all our bicycles manufactured since 2016, the serial number and the frame number appear together on the identification plate.

This is located on the seat tube. You can find this by standing at the rear of your bike, below the seat post. 


You can view the video to locate the frame and serial number here.


For pre-2016 bikes, the serial number can be found on a silver sticker, which also contains a barcode. The sticker is on the frame of the bicycle, located at the back of the seat tube, below the seat post.
