Their description:
SpeedBox Platinum for Giant 2017-2018 is a revolutionary process-control module which suppresses the speed limiter of your electric bike.
The display will show the actual speed, also other data such as maximum speed, average speed, daily distance travelled and range are correctly displayed.
The SpeedBox Platinum tuning kit is activated by briefly pressing the WALK button, which is located at the front of the control panel. After pressing this button, the current speed of 9.9 km/h will be displayed on the control panel for about 3 seconds. This confirms that the SpeedBox Platinum tuning kit has been activated, and the supplementary assistance of your electric motor now works up to a speed of 99 km/h.
When the WALK button is pressed again, the current speed of 2.5 km/h will be displayed. This confirms that the SpeedBox Platinum tuning kit has been deactivated, and everything will work as if the speedbox had never been installed. The supplementary assistance of your electric bike now works up to its original speed limit of 25 km/h.
