Sigma Rox 4.0 Black Cycle Computer The ROX 4.0 GPS supports you with its 30 functions and ease of use during your bike ride, so you can focus on what's essential: fun in the saddle. The extra large display clearly shows data such as altitude profile, speed, distance and training time. Navigation indications and the coupling with the e-bike and external sensors are features obviously included in the ROX 4.0 cycle computer! The ROX 4.0 on-board computer positions itself directly on the handlebar in just a few steps - without cables or sensors. If you wish, you can pair your Rox 4.0 with other sensors for measuring speed, heart rate and cadence. After turning it on, the ROX calculates your position in seconds via GPS and GLONASS. And with intuitive operation via three buttons, you can start your bike ride right away. With the Sigma RIDE app you can set your individual display views.
