Stolen Dahon Bikes: UK Frame-Number Check (Free)
Last updated
Quick answer
Dahon frame numbers are under the bottom bracket or on the main frame tube close to the folding hinge. Unfold the bike completely first, because a folded frame hides most of the tube where the number sits. Hinge and latch part numbers are cast into the mechanism and are not the serial. Run the frame code through Cyclesite's free lookup for an instant UK check against a stolen-bike registry and rider-filed theft reports.
Where Dahon stamps the frame number
Under the bottom bracket, or along the main tube near the folding hinge. The step people skip is unfolding the bike: with the frame closed the hinge area is clamped shut and the bottom bracket is pressed against the rear wheel, so neither location can be read. Open it fully, then look. The numbers cast or printed on the hinge and latch hardware identify those parts, not the bike.
Dahon on the UK used market
Dahon has been the mainstream alternative to Brompton in the UK folding market for years, and the Mariner and Speed turn over steadily second hand. Folding bikes are stolen differently from other bikes: they are taken from offices, station racks, trains and hallways rather than cut from street locks, and they are easy to carry away and hard to describe afterwards. The frame code is often the only thing tying one to its owner.
FAQs
- Where is the frame number on a Dahon?
- Under the bottom bracket or on the main frame tube near the folding hinge. Unfold the bike completely first, because folding conceals both.
- Is the number on the hinge the serial?
- No. Hinge and latch part numbers identify the hardware. The frame number is stamped or printed on the frame tube itself.
- What if a used Dahon has no receipt?
- Common on a bike bought years ago as a commuter. Run the frame code through Cyclesite's free stolen-bike check and confirm the number is on the frame rather than only on a sticker.
