Where is the frame number on a Cowboy bike?
Find your Cowboy bike frame number before you buy, sell or register it.
Find your Cowboy bike frame number before you buy, sell or register it.
Cowboy bikes have a clearly documented frame number. Cowboy says it is underneath the bike, just below the bottom bracket. There should also be a QR sticker and a code starting with CBFM or FM. Once the bike is activated, the frame number can also be found in the Cowboy app under Settings, Advanced, Serial Number.
That number matters. It helps you register the bike, check if it has been reported stolen, prove ownership, value it and sell it with more buyer confidence. Here is where to find it, how to read it, and how to check it before you buy.
Check a Cowboy frame number
Free, instant, no signup. Enter the number stamped on the frame to check it against a stolen-bike registry and rider-filed theft reports.
The frame number on a Cowboy bike is underneath the bike, just below the bottom bracket. Look for a QR sticker and a code starting with CBFM or FM. Once activated, the same number should be visible in the Cowboy app under Settings, Advanced, Serial Number.
This is the most common place to find a Cowboy frame number. It is the part of the frame between the pedals, on the underside.
Make sure you copy the full number. A single missing or misread character can give the wrong result.
If the number is not under the bottom bracket, check these places next:
On older bikes, repainted frames and heavily used bikes, the number can be harder to read. If it has been scratched off, covered, filed down or looks tampered with, treat that as a serious warning sign.
Cowboy says the frame number can start with CBFM or FM, with CBFM18A00967 as an example. The MAC address is different. It is the bike’s digital identifier, not the frame number.
Do not use the model name, tyre size, barcode on a shop label, or any number printed on a component. The frame number belongs to the bike frame itself. For example, these are not usually the frame number:
The number you want is the unique frame code that belongs to the frame itself.
Cowboy has both a frame number and a MAC address. The frame number is the physical bike identifier. The MAC address is the digital identifier. For police, insurance, resale and stolen-bike checks, use the frame number.
A frame number is one of the most useful details on a used bike. It connects a Cowboy to its owner, its registration record and any stolen-bike reports.
You may need it to:
If you own a Cowboy, take a photo of the frame number and keep it with your receipt. If the bike is ever stolen, that detail can make a real difference.
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:
Red flag. Be careful if the seller refuses to show the frame number, says they cannot find it, gives only a partial code, or pressures you to pay quickly. A genuine seller should understand why you are checking.
Found the number? Run a free stolen-bike check before you buy. Enter the Cowboy frame number into the checker and look for any matching reports. It only takes a moment, and it can help you avoid buying a bike with a bad history. If the bike looks clear, you can also value it and compare similar Cowboy bikes for sale.
Report it as soon as possible. You will usually need the frame number, photos, make, model, colour, size, location and any unique marks or upgrades.
Include anything distinctive, such as upgraded wheels, unusual tyres, scratches, stickers, lights, mudguards, racks or replacement parts. The more detail you provide, the easier it is to identify the bike if it appears for sale.
Underneath the bike, just below the bottom bracket. Look for the QR sticker and code starting CBFM or FM.
Check underneath the bike below the bottom bracket, then confirm it in the Cowboy app if the bike is activated.
Start underneath the bottom bracket. The code should be on the QR sticker area.
No. Cowboy says the MAC address is the bike’s digital identifier. The frame number is the physical identifier.
Ask the seller to unlink the bike before you pay. Second-hand buyers may need the previous owner to unlink the bike in the app.

The quickest place to find a Cowboy 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 Cowboy can be a brilliant buy, but the frame number is the detail that protects you.
