READY TO GO AT ANY TIME! The ROX 4.0 bike computer is positioned directly on the handlebars in just a few simple steps without any cables or sensors. If you want, you can pair your ROX 4.0 with additional sensors to measure speed, heart rate and cadence. Once switched on, your ROX determines your position within seconds using GPS and GLONASS. Just use the three intuitive buttons to start cycling right away. The SIGMA RIDE app also lets you individually choose the display view.
LARGE DISPLAY: The high-contrast display is very easy to read even while driving due to its 2.4 inch diagonal and the extra-large digits.
RED CIRCLE: The innovative Red Circle at the top right of the display has a coloured background and offers you an innovative display of your training data.
EVERYTHING IN SIGHT: The SIGMA RIDE app allows you to set your individual display view. Choose from six different views with three values each. The current speed and time are always shown on the display.
BEST MEASUREMENTS: You need even more data or even higher accuracy for your values? Thanks to ANT+ and BLE, you can also pair external sensors such as speed, heart rate and cadence sensors with your ROX 4.0.
HIGH ALTITUDE: A highlight of the ROX 4.0 is the integrated air pressure sensor. With the help of this barometric measurement, it reliably provides information about the altitude, determines inclines and declines, for a precise recording of your route. You can also view a graphic altitude profile on the ROX 4.0. The starting altitude at the beginning of the tour can be calibrated automatically via GPS or you can set your altitude manually.
PIONEER: Connect your ROX 4.0 to the komoot app and leave your smartphone in your pocket. Get turn-by-turn directions on your ROX 4.0 using the komoot app. Show them either as an arrow on the display or inside the red circle. The coloured bars within the red circle on the display count down the distance to the next turn. The closer you get to the turn, the fewer bars are shown. Next to the circle, you will also see how many metres are left until the next turn.
E-BIKE READY: On the road with your e-bike? No problem. The ROX 4.0 is e-bike ready and can be easily paired with a large variety of e-bikes. Your GPS bike computer connects to a compatible e-bike system and shows you the current support level, battery status, light and other data on the display. You can find compatible e-bike systems here: https://rox.sigmasport.com/de/e-bike-compatibility/
