The SpeedBox 1.1 for Bosch Smart System is a game - changer for your e - bike. It allows you to suppress the speed limiter, giving you more freedom on your rides. If you want accurate speed and all riding data during your journey, opt for the SpeedBox 1.1 B.Tuning for Bosch. You can view real values right on your phone with the SpeedBox App. To activate all functions correctly, enter the menu after the first startup of your e - bike post - tuning installation and set the wheel circumference. Remember, activate or deactivate the tuning when the e - bike is stationary, not while riding. Activate the tuning by briefly holding the “ - ” button to activate the WALK assist function. Your e - bike display will show 3.5 km/h (2.2 mph), and you can ride up to 35 km/h. You can change the speed limit up to 99 kph, but to reduce error codes, we suggest not exceeding 35 km/h. Deactivate the tuning by pressing the “ - ” button again for the WALK assist function. The display will show 2.5 km/h (1.6 mph), and the speed limit resets to 25 km/h. For e - bikes without the WALK assist function, switch between two assistance modes twice (press - + - +). Set the maximum speed limit by shifting from TURBO mode: eMTB - TOUR+ - ECO - TOUR+ - eMTB - TURBO. After the ride, keep the bike on until the display shows 0.0 km/h. Our SpeedBox uses original connectors for easy installation and disassembly. We also provide detailed instructions and videos. If installing on a new bike, ride it for at least 10 km before activating the tuning. Connect male - female connectors in the lock direction. Note that using modified e - bikes on public roads may be illegal in some countries. The manufacturer is not liable 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 firmware, and following speed and stopping guidelines.

Hey there! Here's a simple guide to using your SpeedBox 1.1 for Bosch Smart System. First, after installing the tuning, when you start your e - bike for the first time, go into the menu and set the wheel circumference. This gets all the functions working properly. Before you start your ride, and only when the bike is standing still, you can activate the tuning. Press and hold the “ - ” button to turn on the WALK assist function. Your display will show 3.5 km/h, and you can now go up to 35 km/h. You can change the speed limit, but it's best not to go over 35 km/h to avoid error codes.
