“Search & Go” navigation allows you to find a specific location and navigate there. You can enter an address into the SIGMA RIDE app on your smart phone or click on a point on the map. Trail preferences (bike trails, dirt roads, paved roads, and running/hiking trails) can be set individually. The track thus created can be started directly on your ROX 4.0 or saved in the RIDE app for later.
The track navigation allows you to precisely ride a planned route. To do this, create a track in the SIGMA DATA CENTER or with a tour portal of your choice (komoot, Strava, etc.) and import it into the SIGMA RIDE app. You can then start your tour in the app and ride it right away or save it and start it later on your bike computer. This allows you to navigate your tour without a connection to your smart phone.
During navigation, the track and turn-by-turn directions are shown on the ROX 4.0 display. A turn arrow and an acoustic signal tell you when to turn next. To make absolutely sure that you don’t miss any path, the red circle shows the distance to the next turn-off as coloured bars that get shorter as the turn-off gets nearer. The ROX 4.0 also shows the street name. If you leave the track, the ROX 4.0 sends you a notification and displays the shortest route back to it. The track view zooms automatically with your speed so that you are never surprised by a curve. If you leave the track, the zoom level is increased automatically so that you can always see the track and find your way back to it quickly.
A true highlight of the ROX 4.0 is the integrated air pressure sensor. It uses barometric readings to determine inclines and declines and provide you with reliable information about altitude, allowing a precise recording of your track. You can also call up a graphical altitude profile on the ROX 4.0. The home altitude at the beginning of the tour is determined automatically from GPS, or you can set altitude manually.
You ride an e-bike? No problem. The ROX 4.0 is e-bike-ready and can be easily connected to many e-bikes. Your GPS bike computer establishes a connection to the compatible e-bike system and shows you the current assist mode, battery status, and light and other data on the display. You can use this list to find out if your E-BIKE is compatible with the ROX 4.0.
Do you need more data or even greater accuracy for your values? ANT+ and BLE enable you to connect external sensors such as speed, heart rate, and cadence sensors to your ROX 4.0. You can find accessories sets with various sensors for your ROX in our shop.
You can use the SIGMA RIDE app to collect your training data, transfer them to your smart phone via BLE, and quickly set your favourite display views on your smart phone.
