SpeedBox 1.3 makes it possible to double the speed limit of the e-bike from the original 25 km/h to 50 km/h. After installing the chip, real data up to 23 km/h are displayed on the e-bike display.

How does SpeedBox 1.3 work?

You can activate the SpeedBox 1.3 chip on the control panel of the e-bike. After pressing the LIGHT button, the active lights icon will briefly appear on the display, and from that moment you can drive at a speed of 50 km/h. You can turn off the chip function by pressing the LIGHT button again.

If you want to use the SpeedBox at the same time as the lights, we recommend buying a Bafank cable for lighting .

Assembly

To connect the SpeedBox chip to the e-bike, we use colored connectors equipped with a key for correct connection, which is why installing the chip is really easy. We have written detailed instructions and filmed videos, thanks to which each customer can install the SpeedBox by himself. Dismantling the tuning chip is as easy as mounting it. If you have any problem with connection, do not hesitate to contact us.

If you are going to install the SpeedBox on a completely new bike, you need to ride it for at least 1 km before starting the chip for the first time.

WARNING

Operating an electric bicycle equipped with a chip to remove the speed limit may be illegal in some countries. An electric bicycle equipped with a Chip loses the status of a bicycle according to EN15194:2017, therefore its operation may not be in accordance with the applicable legislation for the operation of electric bicycles on roads (including roads intended exclusively for cyclists and pedestrians). Installing the Chip may result in the loss of the warranty on the drive or bicycle. The manufacturer or seller is not liable for any damage to health or life or property. Use at your own risk.

LIFETIME WARRANTY

It covers the functionality and compatibility of the chip on the current and previous firmware of the drive at the time of sale . The warranty does not cover the inoperability of the chip after a later update of the drive, with which the chip may no longer be compatible!

WARNING BEFORE UPDATING

Before visiting the service center, it is necessary to physically remove the Chip from the drive! The Chip manufacturer does not recommend updating the drive. If using a mobile application (e.g. Ebike flow), turn off automatic updates. If this is not necessary, please always consider updating the drive. Each update contains improved anti-tuning software that can detect the Chip and disable the Chip or temporarily block the drive (Emergency mode / Limbo mode). In such a case, we recommend removing the Chip and checking the functionality of the drive.
If the drive works without removing the Chip (i.e. the Chip is defective), contact us with an exact description of the bike and the situation. If the problem persists (i.e. the drive itself is defective, not the Chip), please visit your bike dealer.
