You are all set.
The 2-inch high-contrast display’s dimensions and extra-large numbers are make it easy to read, even during a ride.
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.
EVERYTHING AT A GLANCE
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.
READY TO GO ANY TIME!
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.
FOR DATA COLLECTORS
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. 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.
Intelligent navigation functions
SEARCH & GO
“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 R4 GPS or saved in the SIGMA 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.
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.
You ride an e-bike? No problem. The R4 GPS 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 R4 GPS.
BE THERE LIVE
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.
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 OVER CLAMP BUTLER
The Over Clamp Butler enables you to perfectly align your R4 GPS 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 LONG BUTLER
The Long Butler has more distance from the handlebars and promotes an athletic posture. You can mount it on handlebars with diameters of 25.4 and 31.8 mm in a few easy steps and use a screw to secure it against theft. The Long Butler is available in our online shop as an accessory.
