Kiox 400C is the perfect display for the trail. It is securely mounted on the top tube and thus optimally protected against shocks and impacts. It shows you the relevant data exactly when you need it, thanks to dynamic display functionality—completely without manual screen switching. When riding uphill, you see power, cadence, and elevation gained. When riding downhill, you see your speed. You can charge your devices while riding through the USB-C port. The display excels with a high brightness of up to 1,000 cd/m² and automatically adjusts to ambient light conditions. The external charging function is not possible in the following cases: - With all models of the Drive Unit BDU37YY - With the Drive Unit BDU31YY, if the Multi-Purpose Port (MPP) is configured as a High Power Port (HPP) or as a light port > 6 Watts - With the Drive Units BDU38YY, BDU34YY, BDU33YY, when the High Power Port (HPP), the Low Power Port (LPP), and light ports > 6 Watts are simultaneously active.
