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.

Warning

Rules for using derestricted e-bikes vary by country, so check local legislation before riding.
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.
Installation may also void your e-bike warranty.
For your safety, use appropriate protective gear and ride with maximum caution.
