Speedbox Brose 3.1 speed increasing device

Smart third-generation tuning for Brose and Specialized motors, including the SRAM Powertrain.

SpeedBox 3.1 for Brose unlocks the speed limiter and allows riding at an almost unlimited speed, which will depend only on the pedaling cadence.

The tuning kit can be activated directly on your bike’s controller. By activating the WALK assist function shortly, a value of 99 km/h (62 mph) is displayed. From now on, you will be able to ride at a speed of 40 km/h, 50 km/h and even more than 60 km/h.

To deactivate the tuning kit, activate the WALK assist function shortly again. The value of 25 km/h (16 mph) will appear on your display and the speed limit will reset to 25 km/h. Your e-bike will then work the same as before installation of the tuning.

SpeedBox was also designed for e-bikes that do not have a classic control unit with WALK assist function. In this case, you can just use the combination of + - + - buttons and SpeedBox will be activated. You can easily deactivate SpeedBox in the same way.

You can set the maximum speed of electric assistance by switching modes three levels down and then three levels up: TURBO TRAIL ECO OFF ECO TRAIL TURBO. An actual speed limit will be displayed after that. The maximum speed of electric assistance can be adjusted by briefly activating the WALK assist function or by turning the rear wheel 360°. The speed will always increase by 5 km/h. The last displayed limit will be saved after 5 seconds of inactivity.
