Stolen Rockrider Bikes: UK Frame-Number Check (Free)
Last updated
Quick answer
Rockrider frame numbers are stamped underneath the bottom bracket, between the pedals, and are often repeated on a barcode label. On the electric E-ST models the motor housing can cover the shell, so check the down tube as well. The model reference such as ST 500 is not the frame number. Run the frame number through Cyclesite's free lookup for an instant UK check against a stolen-bike registry and rider-filed theft reports.
Where Rockrider stamps the frame number
Underneath the bottom bracket, between the pedals, with the same code frequently repeated on a barcode label elsewhere on the frame. If the two disagree, trust the stamping. On the electric E-ST 500 the motor housing sits over the shell, so check the underside of the down tube instead. The Decathlon product reference and the model name, ST 100, ST 500 or ST 900, identify the model rather than the individual bike and are useless for a stolen-bike check.
Rockrider on the UK used market
Rockrider is Decathlon's in-house mountain bike brand and one of the highest-volume bike names in the UK, which puts a lot of them on the street and a lot of them in theft and resale listings. The ST 100 and ST 500 are entry-price bikes bought as first mountain bikes and commuters, so receipts go missing routinely and the buyer rarely has any paperwork to inspect. That makes the stamped frame number the only dependable identifier on most used examples.
FAQs
- Where is the frame number on a Rockrider?
- Stamped underneath the bottom bracket, between the pedals, and often repeated on a barcode label. On the electric E-ST models check the down tube, because the motor housing covers the shell.
- Is the Decathlon product reference the frame number?
- No. The product reference and the model name such as ST 500 identify the model, not the individual bike. The frame number is the unique code stamped into the frame.
- What if a used Rockrider has no receipt?
- Very common at this price point and not disqualifying on its own. Check that the number is stamped into the metal rather than only on a label, then run it through Cyclesite's free stolen-bike check.
