Bike computer SIGMA ROX 4.0 Endurance GPS White HR Set

The SIGMA ROX 4.0 Endurance GPS is a bike computer with navigation, barometric altitude measurement and e-bike data support. The set includes a heart rate transmitter with chest strap, a wireless speed sensor and a wireless cadence sensor.

Important information about sensors and GPS

• Cadence, power and heart rate functions require sensors which, according to the supplied information, are not included and must be purchased separately.
• Speed and distance data are based on the GPS signal. Accuracy depends on the capabilities of the technology; GPS satellite coverage may be insufficient in some areas, so accuracy may vary.

Functions

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

Navigation and use

• For navigation, enter an address in the SIGMA RIDE app or select a point on the map. Route surface preferences can be set to bike trails, dirt roads, paved roads, or running and hiking trails. The created route can be started on the device right away or saved in the app for later.
• During navigation, the display shows the route and turn-by-turn directions. An arrow and audible signal alert you to a turn. The coloured bars in the Red Circle indicate the distance to the next turn, and the number of bars decreases as you approach it. The street name is also displayed. If you deviate from the route, a new route to the destination and an updated elevation profile are created using the SIGMA RIDE app.
• Tracks can be created in SIGMA DATA CENTER or on a route platform of your choice, such as komoot or Strava, and imported into the SIGMA RIDE app. You can start a route in the app or save it and start it later on the bike computer. A saved route can be followed without a smartphone connection.
• The computer can be mounted on the handlebars without cables. After the device is switched on, GPS and GLONASS determine your position within a few seconds. Three-button operation lets you start using the device, and display views can be configured in the SIGMA RIDE app.
• The high-contrast display has a 2.4-inch diagonal and large digits. The Red Circle in the top-right corner shows training data against a coloured background. Up to 6 views can be configured in the app, each with 3 data values. Current speed and time are continuously displayed.
• The integrated barometric sensor measures altitude changes, climbs and descents; a graphical altitude profile can also be viewed on the display. The starting altitude is determined automatically using GPS or can be set manually.
• The device can connect to many compatible e-bike systems. The display can show the support mode, battery status, lights and other data.
• External speed, heart rate and cadence sensors can be connected via ANT+ and BLE. Training data can be transferred to a smartphone via BLE, and data and statistics can be viewed in real time using the live view in the SIGMA RIDE app. Display views can also be changed while riding.
• Smart notifications show incoming calls and messages from a smartphone on the display.

Mounts

• The Over Clamp Butler mount lets you position the device above the stem, including when using a short stem. It fits handlebars with diameters of 31.8 mm and 35 mm.
• The classic SIGMA GPS handlebar mount can be installed without tools using two cable ties. It can be fitted to the handlebars or stem and fits handlebars of all sizes.
