In fact, the new engine is compatible with the" eBike Flow App" with the KIOX 300 display.
ENGINE PLUGS AND TUNING COMPATIBILITY: The new 2022 Bosch Smart System comes with completely new engine plugs which are rounded in shape. The previous generation of Bosch engines does have squared plugs and therefore are NOT compatible with the new Smart System motor ports.
