The Sigma 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 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 the intuitive use via three buttons you can immediately set off for your bike ride. With the SIGMA RIDE app you can set your individual display views. The high-contrast display with 2.4-inch diagonal and very large digits can be read very well even when running. The innovative Red Circle at the top right of the display is colorful and offers you an innovative and compelling representation of your training data. Through the SIGMA RIDE app you can set customized views of the display. Here you can set up to six views with three values each. The current speed and time are permanently shown on the display. The Over Clamp Butler allows you to perfectly orient your ROX 4.0 cycle computer even with short stems. In this way, the computer head can be positioned in the center, above the stem, at the height of the handlebar. This allows you to have space and order on your handlebars and to have all the values in view not only when you go mountain biking. The Butler fits handlebars with a diameter of 31.8 and 35mm. The classic SIGMA GPS handlebar mount can be attached in seconds without tools using two cable ties. In this case you can choose between handlebar mounting or handlebar stem and it is suitable for handlebars of all sizes. The real highlight of the ROX 4.0 is the integrated air pressure sensor. Using this barometric measurement, the sensor reliably provides you with information on altitude, calculates climbs and gradients, thus allowing you to accurately record your route. On the ROX 4.0 you can also view an altitude graph. The starting altitude at the beginning can be automatically calibrated via GPS or you can set your altitude manually. Connect your ROX 4.0 with the komoot app and leave your smartphone in your pocket. Through the komoot app you will receive direction directions on your ROX 4.0. These can be viewed in the form of an arrow on the display or within the Red Circle. The circle on a red background on the display counts down the distance to the next turn via colored bars. The bars decrease as you get closer to the detour. Next to the Circle you are also shown how many meters are left to the next detour. Are you out and about with your e-bike? No problem. The ROX 4.0 is e-bike ready and can be paired very easily with many e-bikes. Your GPS cycle computer connects with the compatible e-bike system and indicates the current level of support, battery status, light and other data on the display. With this list, find out if your E-BIKE is compatible with the ROX 4.0. Do you need more data or greater accuracy of your data? Thanks to ANT + and BLE it is also possible to couple external sensors such as speed, heart rate and pedaling cadence to your ROX 4.0. Accessory sets are available for your ROX with different sensors. With the SIGMA RIDE app, you can transfer your training data via BLE to your smartphone, collect your training data and set your favorite display views on your smartphone in a flash. With the LIVE function of the SIGMA RIDE app, you can conveniently consult and analyze the most important data and statistics in real time on your smartphone. Record your data with the cycle computer and analyze them immediately in the Live view of the SIGMA RIDE app. Here you can set up your own custom display views very easily. Smart notifications connect you with the outside world even during training. You are informed on the display in the event of incoming calls and messages on your smartphone.
