The SpeedBox 1.1 B.Tuning for Bosch Smart System offers a one - of - a - kind connection between your e - bike and mobile phone. It cleverly suppresses the e - bike's speed limiter, giving you a more thrilling ride. All your actual speed and other riding data will be accurately shown on your phone's screen through our SpeedBox App. To use all the functions properly, after installing the tuning, turn on your e - bike, enter the menu, and set the wheel circumference. Remember, activate or deactivate the tuning when the e - bike is stationary, not while riding. You can control this tuning easily. Use the mobile app or briefly activate the WALK assist function on your e - bike's control unit (hold down the “ - ” button). Once activated, your e - bike display will show 3.5 km/h (2.2 mph), and you can reach speeds up to 35 km/h or more. You can adjust the speed limit as you like (up to 99 kph), but to avoid error codes, we suggest not going over 35 km/h. To deactivate, press the “ - ” button again. If your e - bike doesn't have the WALK assist function, switch between two assistance modes twice (press - + - +). When you first open the SpeedBox App, you'll need to set a PIN and then a service password. You can set the maximum speed limit by switching modes: TURBO - eMTB - TOUR+ - ECO - TOUR+ - eMTB - TURBO. After that, the actual speed limit will show up. You can switch the maximum electric assistance speed by briefly activating/deactivating the WALK assist or turning the rear wheel 360°. The last limit shown will be saved after 15 seconds of inactivity. After your ride, keep the bike on until the display shows 0.0 km/h. Don't remove the display until the 'countdown' process is done. Our SpeedBox products use original connectors, making installation and disassembly a breeze. We also have detailed instructions and videos. If you're installing on a new bike, ride it for at least 10 km before activating the tuning. When connecting the male - female connectors, follow the lock direction and don't rotate them. Note that using a modified e - bike on public roads may be illegal in some countries. The manufacturer isn't responsible for damages. E - bikes with SpeedBox can only be used on private property at your own risk. Using SpeedBox may void your e - bike's warranty. We recommend using safety gear, not updating the e - bike's firmware, and following some riding and stopping tips for a smooth experience.
