SIGMA ROX 4.0 GPS cycle computer with chest strap R1 DUO Comfortex+

The cycling computer ROX 4.0 GPS with its 30 functions and easy operation will support you on your walk so that you can focus on the most important thing: enjoying your bike ride. The extra large display shows data such as height profile, speed, distance and training time. The R1 DUO Comfortex+ chest belt will accurately measure your heart rate and pulse. Navigation instructions and connection to the e-bike and external sensors are a matter of course for the ROX 4.0 cycle computer! If you want, you can buy additional sensors for the Rox 4.0 cycle computer - for measuring speed, heart rate and pedaling frequency. Immediately after switching on, ROX searches for your location using GPS and GLONASS within a few seconds. Combined with the intuitive three-button control, you can start driving immediately. You can customize the display of data using the SIGMA RIDE application.
