Bosch Kiox (BES2): pair with the eBike Connect app via Bluetooth
The classic Kiox has Bluetooth and pairs with eBike Connect (not eBike Flow). Five minutes; no dealer needed.
Step by step
- Install 'Bosch eBike Connect' and create or log in to an account. Set your phone to the language you want the app in before registering.
- Switch the Kiox on. Open Settings > 'Bluetooth' (on older firmware: My Kiox > Bluetooth) and set it to on / 'Pair new device'.
- In the app tap 'Connect eBike' or the + symbol. The app searches; select the Kiox when it appears.
- Confirm the pairing code shown on the Kiox in the app.
- Once connected, the app shows your bike; rides, lock and firmware updates for the display now run through it.
Tip: Pair from inside the eBike Connect app, not from the phone's Bluetooth settings; a pairing made in the phone menu often blocks the app from connecting.
Can't find it?
If the Kiox does not appear: forget it in the phone's Bluetooth list, switch the Kiox off and on, and search again with the app open. eBike Flow will never find a BUI330; that app is for the Smart System.
Frequently asked

Still stuck? Take a photo of the display and show it to a local e-bike workshop. Bring the bike's system name (e.g. Bosch Performance Line CX) and the exact code; that saves diagnostic time and money.
