**Quick answer:** The frame number on a Fantic is usually near the bottom bracket, but the mid motor and suspension linkage often cover that area. Check the underside of the down tube and the head tube as well, and do not use the number on the motor casing.

On a Fantic, check underneath the bottom bracket first, but expect it to be crowded. Fantic builds electric mountain bikes with a mid-mounted motor and full suspension, so the motor housing and the linkage both sit around the bottom bracket. If the shell is covered, check the underside of the down tube and the head tube.

## Start under the bottom bracket.

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

## What a Fantic frame number looks like

A unique alphanumeric code stamped or laser-etched into the frame. Fantic does not publish a serial format, so read the whole code.

### Not the frame number

- Fantic Integra
- Fantic XF1
- Fantic Issimo
- Motor serial number
- Battery serial number
- Shock serial number
- Fork serial number
- Safety standard numbers

## Buying a used Fantic

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

## Frequently asked questions

### Is a Fantic 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 Fantic bikes have a frame number?

Most Fantic 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.

### Where is the frame number on a Fantic Integra?

On most Fantic Integra electric mountain bikes, check underneath the bottom bracket first. If the motor housing covers the shell, look along the underside of the down tube. The number on the motor casing identifies the motor, not the bike.

### Where is the frame number on a Fantic XF1?

On most Fantic XF1 electric mountain bikes, check underneath the bottom bracket first. If the motor housing covers the shell, look along the underside of the down tube. The number on the motor casing identifies the motor, not the bike.

### What if the Fantic 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 Fantic 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 Fantic bike in the UK?

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