Tutorial: Add a Kiox 300, 500 or SmartphoneGrip Display to Your Bosch System Controller

This is how to add a Kiox 300, 500 or SmartphoneGrip display to your Bosch System Controller easily and without much effort.

The easiest solution would of course be to pair an Intuvia 100 display via bluetooth, see our video. Here we will see how to add a Kiox 300, 500 or a Bosch SmartphoneGrip display to the System Controller, because all 3 use the same bracket. So we will see how to mount the bracket and then you decide whether to add a Kiox or the SmartphoneGrip.

For mounting the bracket and connecting it to the System Controller, there are two options:

1. 1. The classic method with two cables: one cable is laid between the motor and the display bracket and another cable is laid between the display bracket and the System Controller.
   2. The second mounting method arrived with the 2024 models. There is in fact a new Y-shaped display cable, which replaces the two cables of the first method.

Classic method with two cables

1. First disassemble the System Controller by unscrewing the small Torx screw, remove it from the upper tube and then disconnect the display cable.
2. With a little dexterity, you will now have to take out this cable that is already connected to the motor by the headset, via the cable grommets, and bring it to the front of the handlebar.
3. Then, you will take a shorter screen cable – about 20, 25 centimeters, or more – it is better that the cable is too long than too short.
   

   

   Remove the System Controller from the upper tube and unplug the cable.

4. This must then be reintroduced into the stem or the headset, depending on the solution chosen. Then this cable is connected to the System Controller.
5. Once connected, you can put the System Controller back in the top tube without forgetting to put the seal back.
6. There you go, we can now mount the support, having screwed the screen interface into the support. When you buy your interface, pay attention to the cable exit. You have the choice between 2 interfaces, one with the cable exit to the front, and the other to the rear. This will depend on where the cables will be connected at the end of the assembly. In our case, we opt for the cable exit to the rear, which allows the screen to be mounted offset to the front of the handlebar, easier to read. The interface with the cable exit to the front allows the cable to be mounted offset behind the handlebar, which protects it better from shocks.
7. We can now insert the two cables into the screen interface. It may be necessary to turn the interface slightly using the small adjustment screw, so that you can easily pass your cables. It doesn’t matter whether the cables are routed on the left or the right.

8. Then screw the screen support back on and place the screen interface in the position that suits you best.
9. You can now attach your Kiox screen or the SmartphoneGrip to this support.

As I said before, this support is compatible with the SmartphoneGrip, the Kiox 500 and the Kiox 300. You also have the option of screwing in a small safety device, which is located on the back of the interface. If you want more information on this device and on the assembly of the Kiox 300, we invite you to watch our full tutorial. The assembly is already complete.

Method with the new Y-display cable

The Y-display cable is connected directly to the motor and then runs through the frame. The shorter part runs to the System Controller and the longer part comes out at the front towards the display bracket, depending on how it is mounted on your bike. So you only have one cable that goes into the display interface and out towards the System Controller. This makes for a slightly cleaner installation.

It’s up to you to decide which method suits you best. Perhaps the first option is the easiest if you already have the System Controller and therefore already have a connection to the motor. In any case, you will find all the parts required for this installation in our online shop. See also our video tutorial.
