I'm waiting on delivery of a Canyon Strive:ON. Looking at screen options as the Bosch Smart System doesn't integrate with Garmin. Is the Kiox 300/500 wireless/Bluetooth?
I had the same idea and it looks like you connect the cable from the motor into the Kiox, and then from the kiox to the system controller on the top tube. So depending on the lenght of the cable from the motor to the system controller, you might need to buy a longer cable. Then you need a short cable between kios and system controller.
