Technical specifications

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.

If we have tested and confirmed compatibility with the latest Bosch firmware and your chip includes the so-called Factory Bootloader (the icon is marked on the back of the chip), you can safely update your SpeedBox via the app.

Installation

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

Recommendations for trouble-free SpeedBox operation

• Keep the e-bike turned on after each ride until the “Countdown” (distance recalculation) is completed.

• During short stops, keep one foot on the pedal to prevent the countdown from starting.

• During longer stops, allow at least part of the countdown process to complete.

• Do not disconnect the display before the countdown is finished.

• Do not perform software updates – disable automatic updates.

• Always activate/deactivate tuning before or after the ride, not during.

• Do not increase the set maximum speed of 35 km/h.
