Unfortunately none of our tuning kits are guaranteed against error codes.

To reduce the risk of errors, follow these steps:

- Avoid updating the firmware of your e-bike. Updating increases the risk of tuning detection

- Disable automatic updates in the eBike Flow App

- Activate/deactivate the tuning before the ride (when the e-bike is standing still), not during riding

Updating your eBike’s motor firmware may block or disable your tuning kit.

We recommend avoiding firmware updates—especially through service centres—unless absolutely necessary. Most updates are optional, and a working eBike doesn’t usually need one.

Keep in mind:

✔ Firmware upgrades can remove tuning compatibility

✔ Tuning is only guaranteed to work with the firmware version available at time of purchase

✔ A blocked tuning kit due to a firmware update is not covered under warranty

If you’re unsure, reach out before updating. We’re here to help you keep your ride running exactly how you like it.
