Unfortunately no tuning kits are 100% guaranteed. You can reduce the risk of triggering an error code by following these simple steps:

If your eBike uses a smartphone app, switch off automatic updates before installing your tuning kit

Remove your tuning kit before doing any software updates

If possible, remove your battery before starting your installation

Keep your average speed below 50km/h

All Speedbox products come with a lifetime warranty. In the unlikely event your product develops a fault or defect. We will replace it for free.

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.
