**Quick answer:** To check a used VanMoof, look for the frame or bike ID on the bike and match it with the VanMoof app, paperwork and seller account. VanMoof does not publish one universal frame-number location or prefix, so check the usual frame locations and never rely on a guessed format.

VanMoof bikes are different from normal used bikes because the app matters as much as the number on the frame. If you are buying used, you need the physical bike identifier, proof of ownership and a clean app handover. Check the usual bike-frame locations first, especially underneath the bottom bracket and around the lower frame. Then make sure the seller can remove the bike from their VanMoof account before you pay.

## Start under the bottom bracket.

This is the most common place to find a VanMoof 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 VanMoof registration email or paperwork.
- With the VanMoof dealer that sold the bike.

## What a VanMoof frame number looks like

A VanMoof identifier may be shown as a bike ID, frame number or serial number depending on model, paperwork and app view. Use the full code exactly as shown on the bike and in the account. If the code on the bike, app and seller paperwork does not match, pause the purchase and ask VanMoof support or the seller to resolve it first.

### Not the frame number

- VanMoof S3
- VanMoof X3
- VanMoof S5
- VanMoof A5
- VanMoof S6
- VanMoof S4
- Electrified
- SmartBike
- Peace of Mind
- Theft Proof
- Apple Find My ID
- SIM or GSM number
- Bluetooth ID
- Charger number
- Battery label
- Motor number
- Order number alone

## The app handover is the real check

The app handover is the key VanMoof-specific check. A genuine seller should be able to show the bike in their account and remove it before ownership transfer.

A bike that still belongs to someone else’s app account can be difficult to activate or prove as yours.

## Buying a used VanMoof

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

With a VanMoof, the bike identifier and the app handover matter together. Match the code on the bike with the VanMoof account and paperwork, make sure the seller removes the bike from their account, then run a stolen-bike check before you pay. A used VanMoof can be a brilliant buy, but the identifier and a clean handover are the details that protect you.

## Frequently asked questions

### Where is the frame number on a VanMoof S3?

Check the physical bike identifier on the frame, starting with the usual locations around the bottom bracket and lower frame, and compare it with the VanMoof app and paperwork. Do not rely on a guessed spot alone.

### Where is the frame number on a VanMoof X3?

Check the bike itself, the VanMoof account and the original paperwork. The app handover is just as important as the number.

### Where is the frame number on a VanMoof S5?

Use the bike ID or frame identifier shown on the bike and compare it with the VanMoof account before buying.

### Can I buy a VanMoof that is still linked to the seller’s account?

Do not complete the purchase until the seller removes the bike from their account and you can activate it properly.

### Is the VanMoof tracking ID the same as the frame number?

No. Tracking technology and physical bike ID are separate checks. Use the physical identifier for ownership and stolen-bike checks.

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

Find the frame number using the locations described above, then record it against your VanMoof. 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.
