Recommendations for trouble-free SpeedBox operation

• Keep the e-bike turned on after each ride until the “Countdown” (distance recalculation) is completed.

• During short stops, keep one foot on the pedal to prevent the countdown from starting.

• During longer stops, allow at least part of the countdown process to complete.

• Do not disconnect the display before the countdown is finished.

• Do not perform software updates – disable automatic updates.

• Always activate/deactivate tuning before or after the ride, not during.

• Do not increase the set maximum speed of 35 km/h.

• SpeedBox is intended for off-road use only and you use it at your own risk.

• The manufacturer is not liable for damage caused by illegal or improper use.
