Bike computer SIGMA ROX 4.0 Endurance GPS White Sensor Set

The SIGMA ROX 4.0 Endurance GPS is a bike computer with GPS and GLONASS, navigation, barometric altitude measurement and battery life of up to 41 hours. It can connect to compatible external sensors and many compatible e-bike systems.

Important information

• Cadence, power and heart rate functions require sensors, which are not included and must be purchased separately.
• Speed and distance data are based on the GPS signal. Accuracy is limited by the capabilities of the technology and may vary in areas with poor GPS satellite coverage.

Functions

• Basic functions: speed, average and maximum speed, distance, net training time, calories (only when connected to and used with a heart rate sensor), time.
• Status functions: current temperature, device battery level, compass.
• Training: pre-installed sports apps – 1; individually adjustable sports profiles – 1 (additional profiles can be saved in the app); individually adjustable training pages – up to 6; individually adjustable training values per page – 3; templates for training views – 1; Auto Pause.
• Heart rate functions (requires an external heart rate sensor): current, average and maximum heart rate, maximum heart rate in %, intensity zones.
• Cadence functions (requires an external cadence sensor): current, average and maximum cadence.
• Altitude measurement: current altitude, gradient in %, altitude graph, altitude gained uphill.
• Navigation functions: turn guidance, heading.
• E-bike functions (only for compatible e-bike systems): range, e-bike battery, human power versus motor power, support level, lights.
• Data analysis: SIGMA DATA CENTER, SIGMA RIDE app; memory – up to 100 hours of training; file format – .fit.
• Sensors: GPS, GLONASS, barometric altitude measurement, ambient light sensor.

Navigation and use

• Enter a destination in the SIGMA RIDE app on a smartphone or select a point on the map. Choose a route preference: bike trails, dirt roads, paved roads, or running and hiking trails. Start the created route directly on the ROX 4.0 Endurance or save it in the app for later.
• During navigation, the display shows the track and turn-by-turn directions. An arrow and audible signal alert you to the next turn. The coloured bars in the Red Circle count down the distance to the turn; fewer bars are shown as you get closer. The street name is also displayed. If you deviate from the suggested route, the device quickly plans a new route to the destination and updates the elevation profile in interaction with the SIGMA RIDE app.
• Tracks created in SIGMA DATA CENTER or a tour portal of your choice, such as komoot or Strava, can be imported into the SIGMA RIDE app. Start the tour in the app or save it and start it later on the bike computer. You can follow the route without a connection to your smartphone.
• The computer uses GPS and GLONASS to determine your position. It can be used without cables or sensors; speed, heart rate and cadence sensors can also be connected. Three buttons provide control, and display views can be set in the SIGMA RIDE app.
• The high-contrast display has a 2.4-inch diagonal and large numbers. The Red Circle in the upper-right corner shows training data on a coloured background. The app lets you configure up to 6 views, each with 3 values. Current speed and time are displayed continuously.
• The integrated air pressure sensor uses barometric measurements to determine climbs, descents and altitude, enabling accurate track recording. A graphical altitude profile is also available. The starting altitude is determined automatically using GPS or can be set manually.
• The computer can connect to many compatible e-bike systems. The display shows the support mode, battery status, lights and other data.
• ANT+ and BLE allow you to connect external speed, heart rate and cadence sensors.
• The SIGMA RIDE app lets you collect training data, transfer it to a smartphone via BLE and configure display views. The app's LIVE function provides real-time access to key data and statistics.
• Smart notifications show incoming calls and messages on the display.

Mounts

• The Over Clamp Butler mount positions the ROX bike computer above the stem, including when using a short stem. It fits handlebars with a diameter of 31.8 mm or 35 mm.
• The classic SIGMA GPS handlebar mount attaches without tools using two cable ties. It can be installed on the handlebar or stem and fits handlebars of all sizes.

• 1 GPS mount.
• 1 USB-C charging cable.
• 1 quick start guide.
• Sigma R1 Duo transmitter and heart rate chest strap.
• Sigma Duo magnetless speed sensor.
• Sigma Duo magnetless cadence sensor.
