Every Speedbox tuning kit comes with a lifetime warranty, offering peace of mind and a guarantee of satisfaction for every rider.

Please note, Speedbox warranty does not cover malfunctions from updating the motor

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
