Each Brompton leaves the factory with two numbers that uniquely identify your bicycle. These are the serial number and frame number.
Post-2022
For all our bicycles manufactured since 2022, only the serial number appears on the identification plate.
Post-2016
For all our bicycles manufactured since 2016, the serial number and the frame number appear together on the identification plate.
The 6 digit frame number is located on the seat tube, at the spot indicated in the second image, circled in yellow. 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.
Pre-2016
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.
You can view the video to locate the frame and serial number here.
