Every Pashley cycle has its own unique frame and serial numbers. These numbers help to identify each bike, and should be noted down for insurance purposes. Both numbers appear on the guarantee card that you received with your cycle. They can also be found on the cycle frame: the frame number is either stamped into a plate that forms the mount for the rear hub-brake arm on the left chainstay (the non-drive side), or under the bottom bracket (where the pedal crank-shaft is held); the serial number can be found on the security label affixed low down on the seat tube (the security label also displays the barcode unique to your cycle, plus a Union Jack).
