Simply retrofit a display holder to your Bosch Smart System e-bike - with the original 1-arm holder retrofit kit. The set contains all the add-on parts you need for mounting the display holder. These include the 1-arm bracket itself, a display cable with a length of 30 cm and a display mount with cable outlet at the rear. Once mounted, you can easily use the Bosch Kiox 300 or the SmartphoneGrip holder on your e-bike.
