Gazelle frame numbers are usually easier to locate than on some brands. Check the bottom of the down tube near the bottom bracket, or under the down tube above the motor on e-bikes. For Gazelle Bloom service checks, Gazelle says the frame number is printed on a white sticker and consists of GZ followed by 8 digits.
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.

The frame number on a Gazelle bike is usually on the bottom of the down tube near the bottom bracket. On Gazelle e-bikes, check under the down tube above the motor. For the Gazelle Bloom, the frame number is GZ plus 8 digits on a white sticker.
Start at the bottom of the down tube.
Gazelle puts the frame number on the bottom of the down tube near the bottom bracket. On e-bikes, check under the down tube above the motor.
- Put the bike somewhere stable and well lit.
- Check the bottom of the down tube, near the bottom bracket.
- On e-bikes, check under the down tube just above the motor.
- Look for a white sticker with the frame number printed on it.
- Wipe away dirt and use a torch if the sticker is hard to read.
- Take a clear photo before typing the number into a checker.
Make sure you copy the full number. A single missing or misread character can give the wrong result.
Can’t find it underneath the bike?
If the number is not under the bottom bracket, check these places next:
- The original invoice or dealer paperwork.
- The Gazelle registration record.
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.
What does a Gazelle frame number look like?
On Gazelle Bloom models, the number consists of the letters GZ followed by 8 digits, and the Gazelle checker asks for only the digits. For other Gazelle bikes, use the full frame number shown on the bike and match it with the invoice or dealer paperwork.
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:
- Gazelle Bloom
- Gazelle Ultimate
- Gazelle Chamonix
- Gazelle Grenoble
- Gazelle Orange
- Gazelle Medeo
- Gazelle Avignon
- Gazelle Paris
- Gazelle Arroyo
- HMB
- C7
- C8
- C380
- Bosch motor number
- Battery serial number
- Display serial number
- Charger number
- CE mark alone
The number you want is the unique frame code that belongs to the frame itself.
GZ plus 8 digits on the Bloom
On the Gazelle Bloom, the frame number is GZ followed by 8 digits, printed on a white sticker and used for its service-action checker.
For used Gazelle e-bikes generally, the main issue is confusing Bosch system numbers with the Gazelle frame number. Use the frame number for ownership and stolen-bike checks.
The detail that protects you.
A frame number is one of the most useful details on a used bike. It connects a Gazelle to its owner, its registration record and any stolen-bike reports.
You may need it to:
- Check if a Gazelle bike has been reported stolen.
- Register your bike.
- Sell your bike with confidence.
- Get an accurate bike valuation.
- Make an insurance claim.
- Report a stolen bike to the police.
- Prove the bike is yours.
If you own a Gazelle, 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.
Buying a used Gazelle? Check the frame number first.
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.
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.
