We use original connectors for the production of SpeedBox chips, so that the installation of the chip is really easy and the connection is correct. We have prepared detailed instructions and recorded videos thanks to which every customer can install the SpeedBox themselves. Disassembling the tuning chip is just as easy as assembly. If you have any problems with the connection, please contact us!
The activation/deactivation of the tuning should always be done before driving and not while driving. Options for the SpeedBox app: Tuning control Setting the maximum auxiliary speed Save and display driving data Possibility to hide tuning Engine diagnosis
If you want to install a SpeedBox into a brand new bike, you need to ride at least 10km on this e-bike before starting the chip for the first time. https://youtu.be/4JNAbzm0KAA?si=Fakwf4L_OZ1S76Io

Disable automatic update in the eBike Flow app. Please note that the warranty for the SpeedBox products does not apply to malfunctions caused by updating the engine.
