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 before installing your tuning kit

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. On completion of your ride allow the bike to turn itself off
