- EXCELLENT BATTERY PERFORMANCE Designed to withstand the longest bike adventures. The ROX 4.0 ENDURANCE has enough power. Thanks to more energy-efficient and high-performance hardware, the battery lasts up to 41 hours, providing ample time to fully enjoy the cycling experience.
- SEARCH AND TRAVEL Using the navigation, you can find your desired location and get there. You can enter an address in the SIGMA RIDE app or click a point on the map. Route options can be customized (bike paths, trails, paved roads, and running / walking paths). The route created this way can be used directly on your ROX 4.0 ENDURANCE or saved in the RIDE app for later use.
- ROUTE CHANGE AND TURN BY TURN DIRECTIONS During navigation, the ROX 4.0 ENDURANCE displays the route and turn directions on the screen. The turn indicator and audible alert warn you of the next turn. To ensure you don't miss a turn, the red circle with colored stripes counts down the distance to the next turn. The closer you get to the turn, the fewer stripes remain. The ROX 4.0 ENDURANCE also shows the street name. If you deviate from the proposed route spontaneously, your ROX, interacting with the SIGMA RIDE app, will instantly plan a new route to your destination with a correspondingly updated elevation profile.
- THIRD-PARTY CONTENT With navigation, you can follow the planned route precisely. To do this, create a route in the SIGMA DATA CENTER (download and system requirements) or in a chosen travel portal (komoot, Strava, etc.) and import it into the SIGMA RIDE app. You can then start the route in the app and ride it immediately or save it to start later on your bike computer. This way, you can manage your route without a connection to your smartphone.
- GREAT SHAPE, BLACK COLOR Stylish, elegant, and sporty. The black ROX 4.0 ENDURANCE stands out with its elegant design and fits perfectly on any bike.
- READY TO RIDE ANYTIME! The ROX 4.0 ENDURANCE bike computer can be mounted directly onto the handlebars in a few simple steps, without any wires or sensors. If desired, you can link the ROX 4.0 ENDURANCE with additional sensors to measure speed, heart rate, and cadence. Once turned on, the ROX determines your location within seconds using GPS and GLONASS. Just use three intuitive buttons and start cycling immediately. In the SIGMA RIDE app, you can also individually choose the screen display.
- LARGE DISPLAY: The high-contrast 2.4-inch display, due to its size and extremely large digits, is easily readable even while cycling.
- RED CIRCLE: The innovative red circle at the top right of the screen features a colored background and offers a new way to display training data.
- EVERYTHING AT A GLANCE The SIGMA RIDE app allows you to customize the screen view. You can set up to six views, each displaying three values. Current speed and time are continuously shown on the screen.
- WHERE THE AIR IS FRESH The main highlight of the ROX 4.0 ENDURANCE is the integrated barometric pressure sensor. It uses barometric readings to determine ascents and descents and provides reliable information about altitude above sea level, allowing for accurate monitoring of your travel route. Additionally, the ROX 4.0 ENDURANCE allows you to choose a graphical elevation profile. The initial altitude at the start of the route is automatically set from GPS, or you can set the altitude manually.
- E-BIKE READY SYSTEM Traveling with an electric bike? No problem. The ROX 4.0 ENDURANCE is ready to ride an electric bike and can be easily connected to many bikes. The GPS bike computer communicates with a compatible e-bike system and displays the current assistance mode, battery status, lighting, and other data on the screen.
- ACCURATE INDICATORS Do you need more data or even greater data accuracy? ANT+ and BLE allow you to connect external sensors such as speed, heart rate, and cadence sensors to the ROX 4.0 ENDURANCE. You can find accessory kits with various sensors for your ROX in our store.
- RELEVANT By using the SIGMA RIDE app, you can collect your training data, transfer it to your smartphone via BLE, and quickly set your desired views on your smartphone. You can read the most important data and statistics from your smartphone using the LIVE function of the SIGMA RIDE app and evaluate them conveniently.
- STAY LIVE Record your data with the bike computer and analyze it instantly using the LIVE view of the SIGMA RIDE app. While cycling, you can very easily set individual screen displays.
- STAY CONNECTED Smart notifications allow you to connect with the outside world even while riding. Notifications about incoming calls and messages to your smartphone are displayed on the screen.
- PERFECT POSITION The Over Clamp Butler allows for perfect alignment of the ROX bike computer, even if you use a short handlebar extension. The computer can be mounted directly above the handlebars, leaving more space on the handlebars and clearly showing all data regardless of the bike you are riding. The Butler fits 31.8 mm and 35 mm diameter handlebars.
- CLASSIC The classic SIGMA GPS handlebar mount can be attached without tools in seconds using two cable ties. This way, you can choose whether to mount the device on the handlebars or on the extension, and the device fits handlebars of all sizes.
