Benefits of connecting
the B.Tuning version with the SpeedBox App
SpeedBox labeled B.Tuning uses Bluetooth technology, which allows you to connect your e-bike to the SpeedBox App. Thanks to this, you can control the tuning, set a custom speed limit, monitor real-time data, save ride records, or even lock the e-bike motor.
Tuning control
Switching the e-bike speed limit from 25 km/h to unlimited mode.
Tuning hide function
After activating the Tuning Hide function, tuning can no longer be turned on using the walk/light button on the e-bike.
Motor lock
In the mobile app, you can temporarily deactivate the e-bike motor and add an extra level of security.

Remote updates

Bosch regularly releases new firmware versions for its motors, which may affect compatibility with our products or increase the risk of tuning detection. Therefore, we strongly recommend not performing these updates in order to ensure the continued full functionality of our products.

However, we continuously respond to these changes by updating our firmware. One of the biggest advantages of the B.Tuning version is the ability to update your SpeedBox directly via the SpeedBox App – without the need to purchase a new chip, even if you have already updated the system.

Installation

Installing the device is easy and intuitive. Choose the option that suits you best — a video tutorial, a printed manual, or a detailed step-by-step picture guide.

Video guide

You can find a detailed installation and tuning activation walkthrough on our YouTube channel

Printed manual

The product package includes a printed manual, including a wiring diagram showing how to connect the chip to the motor

Step by step

The picture guide will walk you through the installation step by step — from removing the motor cover to the test ride. Each step is supplemented with photos and a clear description.

Tuning control

You can activate tuning in the SpeedBox App (Tuning off / Tuning on).
Or you can turn it on using your e-bike controller by activating the WALK function.
The display will briefly show 3.5 km/h (2.2 mph), which means tuning is on — from that moment, no speed limit applies and your speed depends only on the motor output and your pedaling cadence.
Tuning is deactivated the same way.
The display will show 2.5 km/h (1.6 mph) and the e-bike will return to the original 25 km/h limit.
If your controller does not have the WALK function, you can control tuning using the + – + – button combination.

Custom speed limit setting

SpeedBox allows you to set a custom speed limit (for example, to save battery).
You can change the speed limit again in the SpeedBox App.
Or, on the controller, switch to Turbo mode and then toggle 3× down and 3× up in the following order:
→ EMTB → Tour → Eco → Tour → EMTB → Turbo.
The display will show the current limit.
Increase it by 5 km/h with a short activation of the WALK function (or by rotating the rear wheel 360°).
Example: display shows 3.0 km/h = 30 km/h limit, 4.5 km/h = 45 km/h limit, etc.
The last selected limit is automatically saved after 5 seconds of inactivity.

Recommendations for riding and stopping

When stopping briefly, keep one foot on the pedal so the countdown does not start.
When stopping for longer, let the countdown run at least partially.
After a longer ride, the countdown may take several minutes — do not disconnect the display until the process is finished.
