Bike computer SIGMA ROX 4.0 Endurance GPS (White)

The SIGMA ROX 4.0 Endurance GPS is a bike computer with navigation, altitude measurement and support for e-bike data. Cadence, power and heart rate functions require sensors, which are sold separately. Speed and distance are determined using the GPS signal; accuracy may vary in areas with limited GPS satellite coverage.

Functions

• Basic functions: speed, average speed, 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: 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; training view templates: 1; Auto Pause.
• Heart rate functions (requires an external heart rate sensor): current, average and maximum heart rate, maximum heart rate as a percentage, intensity zones.
• Cadence functions (requires an external cadence sensor): current, average and maximum cadence.
• Altitude measurement: current altitude, gradient in %, altitude graph, altitude uphill.
• Navigation functions: turn guidance, heading.
• E-bike functions (only with compatible e-bike systems*): range, e-bike battery status, human power vs. motor power, support level, light.
• Data analysis: SIGMA DATA CENTER, SIGMA RIDE app; memory for up to 100 hours of training; file format: .fit.
• Sensors: GPS, GLONASS, barometric altitude measurement, ambient light sensor.

Navigation and training

• Use the SIGMA RIDE app to enter an address or select a point on the map and create a route. Route preferences can be set for bike trails, dirt roads, paved roads, and running or hiking trails. The route can be started directly on the ROX 4.0 Endurance 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 an upcoming turn. A red circle with coloured bars shows the distance to the next turn; the bars decrease as you get closer. The street name is also displayed. If you leave the suggested route, the device quickly plans a new route and updates the elevation profile in interaction with the SIGMA RIDE app.
• Track files can be created in SIGMA DATA CENTER or on a route platform of your choice, such as komoot or Strava, then imported into the SIGMA RIDE app. Start the route in the app or save it and start it later on the bike computer. The route can be followed without a connection to a smartphone.
• The integrated barometric pressure sensor measures ascents and descents and provides altitude information. A graphical altitude profile can be viewed on the device. The starting altitude is determined automatically using GPS or can be set manually.
• GPS and GLONASS are used to determine your position. The computer can be used without cables or sensors; ANT+ and BLE connectivity allow additional speed, heart rate and cadence sensors to be connected.
• The device is compatible with many e-bikes. When connected to a compatible e-bike system, the display shows the support mode, battery status, lights and other data.
• Training data can be transferred to a smartphone via BLE. The SIGMA RIDE app lets you configure display views, monitor data in real time and analyse it. Incoming calls and messages received on the smartphone can appear on the bike computer display.

Display and mounting

• The high-contrast 2.4-inch display has large numbers. Training data is shown on the screen, with a coloured red circle in the top-right corner highlighting the data. Up to 6 views can be configured, each with 3 values. Current speed and time are displayed continuously.
• The ROX 4.0 Endurance can be mounted on the handlebars and is operated using three buttons. Individual display views can be configured in the SIGMA RIDE app.
• The Over Clamp Butler mount allows the computer to be positioned 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 attached without tools using two cable ties. It can be mounted on the handlebars or stem and fits handlebars of all sizes.

Included

• 1 ROX 4.0 Endurance navigation computer.
• 1 GPS mount.
• 1 USB-C charging cable.
• 1 quick start guide.
