How does SpeedBox 3.1 for TQ work?.
Activate tuning by briefly pressing the assistance mode combinations:
↑↓↑↓ or ↓↑↓↑.
The display will briefly show 99 KMH, indicating that tuning is activated and you can exceed the speed limit, restricted only by your pedaling cadence.
To deactivate tuning, repeat the same combination — the display will show 25 KMH.
You can also activate or deactivate tuning by holding the WALK button and then pressing ↑↓.
It is recommended to activate or deactivate tuning before starting your ride.
Setting the maximum speed.
Set the speed limit by changing the modes in the following sequence:

The current limit will appear on the display.
The limit can be adjusted by turning the rear wheel — each full rotation increases the speed by 5 km/h.
You can also change the limit using the WALK + ↑↓ combination.
The last selected limit is automatically saved after 5 seconds of inactivity.
