    Activating the tuning kit is a breeze – simply use your bike's display. Press the LIGHT button or ????, and witness a display of 99 km/h (62 mph), granting you the freedom to ride at unlimited speeds.

    To deactivate the tuning kit, press the LIGHT button or ???? again. Your display will show a value of 25 km/h (16 mph), resetting the speed limit to 25 km/h, restoring your e-bike to its original configuration.

    Setting the maximum speed of electric assistance is effortless. Switch between modes by toggling three levels down and then three levels up. The actual speed limit will be displayed, allowing you to customize your e-bike's assistance speed. Quick presses of the LIGHT button or a 360° turn of the rear wheel will switch the maximum speed, and the last displayed limit is automatically saved after 5 seconds of inactivity.

    Upgrade your cycling experience in Liverpool with the SpeedBox 3.1 Tuning Chip – the perfect blend of performance and customization for your e-bike. Unleash the power at your fingertips and ride with unmatched freedom!

    Very nice little box.
    This is a great little jewelry box. I don’t have tons of jewelry right now, so this fits everything well, and the leather-look material is very nice. I like the simple design and organization, and it is a nice size to travel with. It looks really pretty sitting on my dresser and goes with the aesthetic of my home well.

    Pretty
    Very nice simple jewelry box. My only issue is spacing to put necklaces is a bit tight, but there is plenty of room in this little guy. I put a lighter next to it, for size comparison.
