How does SpeedBox 1.4 B.Tuning for Bosch work?

This chip is also characterized by its easy operation. You activate the SpeedBox 1.4 B.Tuning chip either in the mobile app or on the e-bike display (always before riding, do not do it while riding!). After briefly activating the WALK function (holding the "-" button), the display shows 3.5 km/h (2.2 mph) and from then on you can ride 35 km/h (35 mph). You can change the default speed limit to any limit (up to 99 km/h), but to minimize the risk of error codes we recommend not to exceed 35 km/h.

You can deactivate the chip function by reactivating the WALK function (holding the "-" button). The display will show 2.5 km/h (1.6 mph) and the 25 km/h speed limit is re-enabled. The e-bike then operates in the same way as before the chip was installed. Do not deactivate while riding.

We have also thought about electric bikes that do not have the WALK function available or active. In this case, you can activate and deactivate the tuning by double switching between the two modes, i.e. the combination of the - + - + buttons.

When you start the SpeedBox App for the first time, you will be prompted to set a PIN. You will then use this PIN every time you run the SpeedBox App again. After selecting the PIN, you will also be prompted to set a service password to use in case you forget the PIN or want to change it.

Set the maximum assist speed by switching modes from TURBO mode down three levels and then up three levels (eMTB - TOUR+ - ECO - TOUR+ - eMTB - TURBO). The current speed limit will then be shown on the display. Switch the maximum assist speed by briefly pressing the WALK button or by turning the wheel 360°. Displaying 2.5 km/h corresponds to 25 km/h, 3.0 corresponds to 30 km/h, 3.5 corresponds to 35 km/h, etc. The last displayed limit is saved after 15 seconds of inactivity.

When you have finished riding, leave the e-bike switched on until the display shows 0.0 km/h permanently. During this phase, the remaining time will be shown on the display. You can then safely switch the bike off and look forward to your next trip.

The SpeedBox App designed specifically for SpeedBox B.Tuning uses Bluetooth technology to connect the e-bike to your mobile phone. After downloading the app and connecting your phone to the e-bike, you can see the current data and ride parameters on your phone's display. You can save individual trips, compare with friends and track your own performance. So you can enjoy your ride to the fullest and leave checking the parameters for later.

SpeedBox App options:

• Tuning control
• Setting the speed limit
• Save and view ride data
• Invisible tuning mode
• Engine diagnostics

The SpeedBox B.Tuning chip is not dependent on the SpeedBox App. However, it is a great add-on that will give you a complete overview of your performance.

Download the SpeedBox App to your phone before ordering the SpeedBox 1.4 B.Tuning chip. You can try the demo version, get to know all the gadgets and at the same time make sure the app is fully functional on your phone. To connect to the SpeedBox B.Tuning chip, your phone must be equipped with Bluetooth 4.0 or higher.

Installation

Original connectors are used to manufacture the SpeedBox chips to make the installation of the chip really easy and the wiring correct. Detailed instructions and videos are available to help any customer handle the SpeedBox installation themselves. Disassembly of the tuning chip is as easy as assembly. If you have any problems with the wiring, please do not hesitate to contact us.

In case you are going to install the SpeedBox on a brand new bike, you need to ride it at least 10 km before running the chip for the first time.

Important

Connect the male-female connectors in the direction of the lock. Do not turn the connectors while plugging them in!

Caution

Please note that the operation of electric bicycles modified in this way on roads may be in contravention of current legislation in some countries. Neither the manufacturer nor the supplier accepts any liability for damage resulting from the use of SpeedBox products. E-bikes equipped with SpeedBox products may not be used on roads, cycle paths or public spaces. E-bikes equipped with SpeedBox products may only be used on your own property, solely at your own risk. Use of SpeedBox products may void your e-bike's warranty.

Please contact us if you lose your service password or pin.

We recommend the use of additional safety features and protective products to prevent injury.

We recommend that you do not update the firmware of your e-bike. Updating increases the risk of tuning detection.

Turn off automatic updates in the eBike Flow settings.

We recommend keeping one foot on the pedal during short stops to avoid triggering the odometer.

For longer stops, allow at least a partial odometer count to run.

Do not remove the display to lock the e-bike until the odometer has been counted.

Activate/deactivate the tuning system during a stop, not while driving.

We recommend that you do not exceed the recommended maximum speed of 35 km/h.
