VDO White - Black VDO R4 GPS computer 2025

The R4 GPS bike computer can be positioned directly on the handlebars in a few easy steps. There is no need to mount cables or sensors.
Your R4 GPS 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.

• Large display: The 2-inch high-contrast display’s dimensions and extra-large numbers are make it easy to read, even during a ride.
• Blue square: The innovative BLUE SQUARE on the upper right corner of the display is highlighted in various colours and offers innovative, interesting display of training data.
• 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 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 R4 GPS 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 blue square 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 R4 GPS 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.
