**Quick answer:** On many TENWAYS bikes, the frame number is under the bottom bracket. On CGO600-series bikes, remove the plastic cover under the bottom bracket to see it. On AGO and Cargo mid-drive models, check the right side near the chainring, just above the motor. TENWAYS says CGO600-series frame numbers start with 1.

TENWAYS gives clear model-specific frame-number locations, and several are not visible until you remove a cover. On CGO600-series bikes, the frame number is under the bottom bracket behind a plastic cover. On mid-drive models such as the AGO X, AGO T, CARGO ONE, AGO Air and Longtail Duo, the number is on the right side near the chainring, above the motor.

## Start under the bottom bracket, then check the cover.

On CGO600-series bikes the number hides behind a removable plastic cover under the bottom bracket. On mid-drive AGO and Cargo models, it sits on the right side near the chainring, above the motor.

1. Put the bike somewhere stable and well lit.
2. Check under the bottom bracket between the pedals.
3. On CGO600-series bikes, carefully remove the plastic cover under the bottom bracket.
4. On AGO X, AGO T, CARGO ONE, AGO Air and Longtail Duo, check the right side near the chainring, above the motor.
5. On the CGO009, check below the CE marking.
6. Take a clear photo before typing the number into a checker.

## What a TENWAYS frame number looks like

TENWAYS says CGO600-series frame numbers start with the digit 1. Use the full number shown on the frame, not just the starting digit. Do not confuse the frame number with CE markings, motor labels or battery numbers.

## The plastic cover is the key detail

The plastic cover under the bottom bracket is the key TENWAYS detail. If you cannot see the number on a CGO600-series bike, it may not be missing. It may be behind the cover.

## Buying a used TENWAYS

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