Introducing the new - generation tuning chip with Bluetooth and a mobile app for your e - bike! This is our most powerful and versatile product yet. It creates a unique link between your e - bike and mobile phone. The SpeedBox 3.0 B.Tuning chip is top - notch, perfectly optimized for an amazing riding experience. It overrides the speed limiter, allowing you to ride at unlimited speeds. With the SpeedBox App, you can monitor and save all your trip parameters on your phone screen anytime, anywhere. How does it work? It has an easy - to - use control unit. You can activate the tuning kit from the mobile app or your bike's display. Press the WALK button, and a 9.9 km/h (6.2 mph) value will show up. From then on, you can reach speeds of 40 km/h, 50 km/h, or even over 60 km/h. To deactivate it, press the WALK button again, and the speed limit will reset to 25 km/h. For e - bikes without a classic control unit with a Walk button, use the + - + - button combination to activate and deactivate SpeedBox. At first startup, the SpeedBox App will prompt you to create a PIN code for security, and then a Service password in case you need to change the PIN. You can set the maximum electric assistance speed by changing modes: Turbo - EMTB - Tour - Eco - Tour - EMTB - Turbo. The actual speed limit will display, and you can switch it by pressing the WALK button briefly or turning the rear wheel 360°. The displayed values correspond to different speed limits, and the last limit will be saved after 5 seconds of inactivity. When using SpeedBox 3.0 with 4th - generation Bosch motors (2020 or later), leave the bike on until 0.0 km/h shows up. The remaining time will display in minutes. Then it's safe to turn off the bike. The SpeedBox App uses Bluetooth to connect your e - bike to your phone. You can view current data and trip parameters, save individual trips, and compare results with friends. It has features like tuning control, trip saving, hide tuning, motor lock, and motor diagnostics. Download the SpeedBox App before ordering the chip.
