E-bike Tuning SpeedBox 1.0 BOSCH SMART SYSTEM (Gen4) The tuning chip for e-bikes with the newest Bosch Gen4 motor and Smart System. SpeedBox 1.0 enables you to suppress the speed limiter on your e-bike. When in use, the display shows the real speed up to 22.2 km/h. After exceeding this speed your actual speed is indicated on the last two digits of the display. Example: - 22.3 corresponds to a speed of 23 km/h - 23.1 corresponds to a speed of 31 km/h If you want to see correct speed and all riding data during your ride, we recommend choosing SpeedBox 1.0 B.Tuning for Bosch. With SpeedBox 1.0 B.Tuning for Bosch, you can see the real values in our SpeedBox App – right on the display of your phone. How does SpeedBox 1.0 work? To activate all the functions of the SpeedBox correctly, it is necessary to enter the menu after the first switching on of the e-bike after the tuning installation and switch to the circumference of your bike. You will activate the SpeedBox 1.0 tuning chip directly on your e-bike’s control unit by activating the WALK assist function shortly (holding down the “-†button). Your e-bike display will show a value of 9,9 km/h (6,2 mph) and from now on you will be able to ride at unlimited speed. To deactivate the tuning chip, activate the WALK assist function shortly again (by holding down the “-†button). Your e-bike display will show a value of 2,5 km/h (1,6 mph) and the speed limit will be reset to 25 km/h. Your e-bike will then work the same as before the chip installation. SpeedBox was also designed for e-bikes that do not have the WALK assist function enabled, or activated. In this case, you can activate/deactivate tuning by switching between two assistance modes twice, i.e. by pressing the +-+- buttons. The "countdown" process will continue concealed during charging, therefore, if you charge your e-bike with a connected battery, you can ignore the following instructions. If you need to remove the battery from your e-bike in order to charge it, you need to wait for the SpeedBox to carry out the "countdown" process after the ride. When you stop your e-bike, the ongoing "countdown" process will be indicated by the increasing riding time. Once the "countdown" process is completed, the riding time stops and the e-bike display shows the correct distance travelled. The countdown process can be interrupted by turning off the e-bike or by setting off, so it does not restrict the use of your e-bike in any way. However, you still need to have the countdown process run regularly to prevent tuning detection.
