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

• If possible, remove your battery before starting your installation
• If your eBike uses a smartphone app, switch off automatic updates
• Once fitted, avoid updating your motor as this increases the chance of detection
• Remove your tuning kit before doing any software updates
• Avoid activating/deactivating the tuning kit mid-ride
• Keep your average speed below 35km/h
• On some eBikes such as models with the Bosch Gen4 motor, a countdown is required to ensure the correct milage is recorded
• After a long ride, the countdown will take several minutes. The bike must remain on while this completes
• When stopping for a short time, keep your foot on the pedal to stop the countdown from starting

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.
