GPS BIKE COMPUTER WITH ALTITUDE MEASUREMENT
The ROX 4.0 GPS has 30 easy-to-use functions that support you during your cycling adventure. This way, you can focus on what matters: the joy of riding your bike. The very large display reliably shows data such as altitude profile, speed, distance, and training time. Navigation tips and pairing with an electric bike and external sensors are a given for the ROX 4.0 bike computer!

LARGE DISPLAY
The high-contrast display with a diagonal of 2.4 inches and exceptionally large digits guarantees perfect readability while riding.
RED CIRCLE
The innovative RED CIRCLE element in the upper right corner of the display is illuminated in color and offers a new interesting way to present your training data.


EVERYTHING IN VIEW
In the SIGMA RIDE app, you can individually set the way data is displayed. You can choose from up to six views, and in each of them, there are three values to set. Current speed and time are constantly displayed on the screen.
READY TO WORK AT ANY TIME!
In a few simple steps, the ROX 4.0 bike computer can be mounted directly on the handlebars – completely without cables and sensors. If you want, you can pair the ROX 4.0 with additional sensors for measuring speed, heart rate, and cadence.
Once turned on, the ROX computer determines your location via GPS and GLONASS within seconds.
Thanks to intuitive operation using three buttons, you can immediately hit the road.
In the SIGMA RIDE app, you can set your own ways of displaying data.

CLASSIC
The classic SIGMA GPS handlebar mount can be installed in a few seconds using two zip ties without the need for tools. You can choose to mount it on the handlebars or on the handlebar stem. The mount fits all handlebar sizes.
WHEN YOU'RE HIGH
The real advantage of the ROX 4.0 is the built-in air pressure sensor. Barometric measurement provides reliable information about altitude, determining ascents and descents, thus enabling precise route recording. On the ROX 4.0, you can also display a graphical altitude profile. The starting altitude at the beginning of the trip can be calibrated automatically via GPS or set manually.
DIRECTION INDICATOR
Connect your ROX 4.0 to the komoot app and put your smartphone in your pocket. Use the komoot app to receive route tips on the ROX 4.0 device. Tips can be displayed as an arrow or in the Red Circle. The red circle on the display counts down the distance to the next turn using colorful segments. The segments decrease as you approach the turn. Naturally, in addition to the Circle graphic, you will read how many meters remain to the next turn on the display.


E-BIKE-READY
Are you riding an electric bike? No problem. The ROX 4.0 EVO is designed to work with many models of electric bikes, and connecting to the e-bike is very simple. The GPS bike computer communicates with the compatible electric bike system and displays your current level of assistance, battery status, lighting, and other data on the display.
DO YOU LIKE TO COLLECT DATA?
With the SIGMA RIDE app, you can transfer training data via BLE to your smartphone, store it, and quickly set your favorite display views on your smartphone. With the LIVE function in the SIGMA RIDE app, you can read and conveniently analyze the most important data and statistics in real time on your smartphone.
