Installation & Use
SpeedBox 1.6 connects via original Bosch connectors for secure and reversible installation. After setup, activate tuning while stationary using WALK assist or the button sequence. To set a custom speed limit, switch modes in the following order:

TURBO → eMTB → TOUR+ → ECO → TOUR+ → eMTB → TURBO

The display will show the selected limit (e.g., 3.5 km/h = 35 km/h). After 15 seconds of inactivity, the setting is saved.

After riding, leave the bike powered on until the display shows 0.0 km/h. This ensures proper data logging and safe shutdown. Do not remove the display before the countdown completes.

Legal & Safety Notice
SpeedBox products are intended for use on private property only. Use on public roads may violate local laws and void your e-bike’s warranty. Always wear protective gear and disable automatic firmware updates via the eBike Flow App to prevent tuning detection.

Additional Notes
Ride at least 10 km before activating tuning on a new bike

Countdown duration may vary after long rides

Activate/deactivate tuning only while stationary

Do not exceed 35 km/h to avoid error codes
