# Where is the frame number on a ROSE bike? Canonical: https://www.cyclesite.co.uk/trust/frame-numbers/rose Last reviewed: 2026-06-11 **Quick answer:** The frame number on a ROSE bike is most likely to be under the bottom bracket. There is no universal ROSE prefix to count on. If there is a QR sticker or printed code under the bottom bracket, match it with the invoice or ROSE support before using it. On a ROSE, check underneath the bottom bracket first. If you find a QR sticker or printed alphanumeric code there, treat it as a strong candidate and match it with the ROSE paperwork or a confirmation from ROSE support. There is no single published ROSE serial prefix or guaranteed location to rely on, so never trust a guessed format. ## Start under the bottom bracket. This is the most common place to find a ROSE frame number. It is the part of the frame between the pedals, on the underside. 1. Put the bike somewhere safe and well lit. 2. Turn it upside down carefully, or place it in a workstand. 3. Look underneath the frame where the cranks meet the bike. 4. Wipe away mud, grease or road dirt. 5. Use a phone torch if the number is hard to read. 6. Take a clear photo before typing the number into a checker. ### If it is not under the bottom bracket - Near the rear dropouts, where the back wheel slots into the frame. - Around the seat tube. - On the underside of the down tube. - Near the head tube at the front of the bike. - On the original ROSE invoice or order confirmation. - In your ROSE account order history. ## What a ROSE frame number looks like A ROSE frame number should be a unique alphanumeric code on the frame or label. Some owners find QR-code stickers under the bottom bracket, but treat that as a candidate to confirm rather than a universal rule. Use the full code shown on the bike and match it with paperwork. ### Not the frame number - ROSE Reveal - ROSE X-Lite - ROSE Backroad - ROSE Pro SL - ROSE Blend - ROSE Root Miller - ROSE Bonero - ROSE Sneak - ROSE Hobo - Di2 serial - Shimano component code - SRAM component code - Wheel serial number - Fork serial number - Order number alone - QR code without matching record ## Direct to consumer, so the order record matters ROSE is direct-to-consumer, so the original order record matters. A used ROSE should come with a frame number that matches the seller’s order or invoice wherever possible. ## Buying a used ROSE A clean-looking bike is not always a safe buy. Before you pay, ask the seller for a clear photo of the frame number and check it against stolen-bike records. You should also ask for: - The original receipt or proof of purchase. - The seller’s name matching the receipt where possible. - Clear photos of the bike from both sides. - A photo of the frame number. - Any service history. - Details of upgrades or replacement parts. ## Bottom line The quickest place to find a ROSE frame number is underneath the bike, near the pedals. Look for a stamped code or barcode sticker, copy the full number, then check it before you buy, sell or register the bike. A used ROSE can be a brilliant buy, but the frame number is the detail that protects you. ## Frequently asked questions ### Where is the frame number on a ROSE Reveal?
