SpeedBox 3.0 – the third generation tuning chip for Brose engines, which allows you to select the desired speed limit for electric assistance. Once installed, you’ll see the correct data on the display (max/vid speed, daily mileage, total distance) and you can change the limit directly from the bike’s controller.
How does SpeedBox 3.0 work?
- Activation by WALK button: after briefly activating WALK, the WALK assist will display 9.9 km/h – from this point on, the assist will work up to 40 / 50 / 60+ km/h (depending on setting).
- Switching off: briefly activate WALK again – the display shows 2.5 km/h and the limit returns to 25 km/h (OEM).
- No screen / no WALK: use the + – + – button combination – SpeedBox can also be activated/deactivated.
- Changing the limit (on screens with modes): switch down 3 levels and up 3 levels:
TURBO → TRAIL → ECO → OFF → ECO → TRAIL → TURBO.
Then briefly activate WALK or turn the rear wheel 360° to confirm the setting.
Displayed value = selected limit:
1,5 = 15 km/h, 2,0 = 20 km/h, 2,5 = 25 km/h, 3,0 = 30 km/h, 9,9 = 99 km/h.
After ~5 seconds of inactivity the new limit is saved.

FAQ

Yes – the + – – + – combination is possible; the limit will be set by a sequence of modes.
Are real speeds above 25 km/h displayed?
Yes – SpeedBox 3.0 maintains the correct display (different from older generations).
