Supports cyclists with its 30 functions and user-friendliness during bike tours, allowing them to focus on what matters most. The ROX 4.0 is E-Bike ready and can be paired with many E-Bikes, such as Shimano STEPS. Thanks to ANT+ and BLE, external sensors like speed, heart rate, and cadence sensors can also be connected. The high-contrast display, with its 2.4-inch diagonal and extra-large digits, is very easy to read even while riding. It can connect to the komoot app via smartphone, and turn-by-turn directions can be displayed as arrows on the screen or within the so-called Red Circle. The free SIGMA RIDE app is an important complement to your SIGMA GPS bike computer, tracking your achievements and helping you reach your personal goals.

Source: GalaxusThe Sigma has an easy-to-read display and comprehensive connectivity. The workmanship is of high quality. The route guidance is sometimes misleading and the operation is not intuitive. There is no protection for the speedometer.
The Sigma ROX 4.0 ENDURANCE is a reliable bike computer with good features, simple operation and solid navigation. We were particularly impressed by the long battery life, the simple set-up and the option to customise the display functions.
