The SIGMA RIDE app allows you to set your display view individually. You can set up to six views, each with two values. Current speed and time are shown continuously on the display.


The ROX 2.0 bike computer can be positioned directly on the handlebars in a few easy steps. There is no need to mount cables or sensors.

Your ROX uses GPS and GLONASS to determine your position within a few seconds of being switched on.
The user-friendly operation with two buttons enables you to start a bike tour right away.
You can use the SIGMA RIDE app to set your individual display views.


Intelligent navigation functions


“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 2.0 or saved in the RIDE app for later.

Tracks from third parties

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.

Turn-by-turn navigation

During navigation, the track and turn-by-turn directions are shown on the ROX 2.0 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. If you leave the track, the ROX 2.0 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.


You ride an e-bike? No problem. The ROX 2.0 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 2.0.

Video tip


You can use the SIGMA RIDE app to collect your training data, transfer them from the ROX 2.0 to your smart phone via BLE, and quickly set your favourite display views on your smart phone. The most important data and statistics can be read from your smart phone in real time with the SIGMA RIDE app’s LIVE function and assessed conveniently.



Record your data with your bike computer and analyse them right away with the SIGMA RIDE app’s LIVE view. You can set your individual display views extremely easily while you’re riding.

Stay tuned

Smart notifications connect you to the outside world even when you’re riding. Notifications of incoming calls and messages to your smart phone appear on your display.


The Overclamp Butler enables you to perfectly align your ROX 2.0 bike computer, even if you have a short stem. For instance, the bike computer can be positioned centrally above the stem at the level of the handlebars. This ensures that there is space and order on your handlebars and that you have a good overview of all values. The Butler fits on handlebars of 31.8 and 35 mm diameters.


The classical SIGMA GPS handlebar bracket can be fixed in place without tools in a few seconds with two cable ties. This gives you a choice between installation on your handlebars or on the stem, and the device fits handlebars of all sizes.
