Riding and stopping recommendations
• Leave the e-bike on after every ride until the display permanently shows 0.0 km/h (kilometre countdown).
• During short stops, keep one foot on the pedal so the countdown does not start.
• During longer stops, allow at least a partial countdown to complete.
• Do not disconnect the display before the countdown is finished.
• Do not perform firmware updates — disable automatic updates.
• Always activate/deactivate the tuning when stationary, never while riding.
• On a brand-new bike, ride at least 10 km before activating the tuning for the first time.
Warning
• The use of unlocked e-bikes varies by country — please check your local legislation before riding.
• SpeedBox is intended for off-road use only and is used entirely at your own risk.
• The manufacturer accepts no liability for damages caused by illegal or improper use.
• Installation may also void the warranty of your e-bike.
• The warranty does not cover malfunctions caused by a motor update.
• For your safety, use appropriate protective gear and ride with maximum caution.
