Stolen GT Bikes: UK Frame-Number Check (Free)

Last updated

Quick answer

GT frame numbers are stamped on the underside of the bottom bracket, including on BMX models. GT mountain bikes and BMX bikes are common theft targets in the UK, so run the number through Cyclesite's free lookup for an instant check against police records, stolen-bike databases and community reports.

Where GT stamps the frame number

On the underside of the bottom bracket shell on the vast majority of GT mountain bikes, and on the bottom bracket area of GT BMX frames. The number is stamped into the metal, not printed on a sticker, so a GT with only a sticker and no stamped number should be treated with suspicion.

GT on the UK used market

GT is well known for both mountain bikes and BMX, and BMX in particular is a high-theft, fast-resale category in UK cities. The Aggressor and Avalanche hardtails, the Zaskar and Sensor trail bikes and the Performer and Pro Series BMX models appear often in used and stolen listings, so always check the frame number before buying.

Yes. BMX is a high-theft, fast-resale category in UK cities, so always check the frame number on a used GT BMX before buying.
