Where to find your serial number
Look on the back of your seat tube for a 10-digit number starting with the year and month of production (e.g. 1903ā¦ = March 2019). On bikes made before 2015, this is a sticker with barcode. On newer bikes, it's a metal badge in the same location.
Your frame number is stamped into the bottom bracket area, on the flat section behind the seat tube.
Either number works for registration. The serial number was introduced in late 2001 ā older Bromptons only have the stamped frame number.
