The SpeedBox 3.0 tuning kit allows you to choose your own speed limit. Once installed, your e - bike's display will show real - time data like maximum and average speeds, daily mileage, and cruising range. Activate the tuning kit directly on your bike's display. Briefly activate the WALK assist function to activate SpeedBox 3.0. A 9.9 km/h (6.2 mph) value will show up, and you can then ride at speeds of 40 km/h, 50 km/h, or even over 60 km/h. To deactivate, briefly activate the WALK assist again. A 2.5 km/h (1.6 mph) value will appear, and the speed limit will reset to 25 km/h. For e - bikes without a classic control unit with the WALK assist function, use the - + - + button combination to activate and deactivate. You can set the maximum electric assistance speed by changing modes: Turbo - EMTB - Tour - Eco - Tour - EMTB - Turbo. The actual speed limit will then be displayed. Switch the maximum speed by briefly activating the WALK assist or turning the rear wheel 360°. Display values correspond to specific speed limits (e.g., 1.5 km/h to 15 km/h). The last limit will be saved after 5 seconds of inactivity. When using with 4th - generation Bosch motors (produced in 2020 or later), leave the bike on until 0.0 km/h is displayed after a ride. The remaining time will show in minutes. Then it's safe to turn off. The SpeedBox has colored connectors for easy installation. We've provided detailed instructions and videos. Disassembly is also easy. If you're installing on a new bike, ride it for at least 10 km before activating the tuning. Note that using modified e - bikes 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 features and protective gear and don't recommend updating the e - bike software. If you do update, uninstall SpeedBox first, update the software, and then reinstall it.
