**Quick answer:** The frame number on a Pendleton bike is usually stamped underneath the bottom bracket, between the pedals. On step-through models with a chaincase or skirt guard, you may need to look past the guard to see the shell clearly.

On a Pendleton, check underneath the bottom bracket first. Pendleton bikes are Halfords town and leisure models, often with a step-through frame, mudguards and a chaincase, so parts of the frame are covered. The bottom bracket shell is still the place to start.

## Start under the bottom bracket.

This is the most common place to find a Pendleton 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 fits 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 sales receipt.
- In your Pendleton registration email or paperwork.
- With the Pendleton dealer that sold the bike.

## What a Pendleton frame number looks like

A unique alphanumeric code stamped into the frame near the bottom bracket. Halfords does not publish a Pendleton serial format, so use the full code rather than looking for a prefix.

### Not the frame number

- Pendleton Somerby
- Pendleton Ashwell
- Pendleton Initial
- Pendleton Brooke
- Frame size
- Basket or rack part numbers
- Halfords stock labels
- Safety standard numbers

## Guards and covers get in the way

Town bikes carry chaincases, skirt guards and full mudguards, and these sit close to the frame around the bottom bracket. If you cannot see the shell, do not force anything. Lay the bike on its side on something soft and use a torch at an angle rather than removing guards.

## Buying a used Pendleton

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 Pendleton 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 Pendleton can be a brilliant buy, but the frame number is the detail that protects you.

## Frequently asked questions

### Is a Pendleton frame number the same as a serial number?

Yes. Most people use frame number and serial number to mean the same thing. It is the unique identifying code attached to the bike frame.

### Do all Pendleton bikes have a frame number?

Most Pendleton bikes have a frame number or serial number. Check the locations described above first; on older frames the marking can be shallow or worn, so clean the area and check in good light before concluding it is missing.

### What if the Pendleton frame number has been removed?

Do not buy the bike. A removed or damaged frame number is a major red flag. It may make the bike harder to register, insure, resell or prove as yours.

### Can I check if a Pendleton bike is stolen by the frame number?

Yes. Use the frame number to run a stolen-bike check before buying. You should also ask the seller for proof of ownership and check that the details match the bike.

### How do I register a Pendleton bike in the UK?

Find the frame number using the locations described above, then record it against your Pendleton. It is free, and you need an account so we know where to send the alert. If that exact number is ever reported stolen to us, we email you. If anyone then lists a bike carrying it, the listing is hidden until the seller proves it is theirs.
