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 a 2.4-inch diagonal and extra-large digits, is very easy to read even while riding. It can be connected to the komoot app via smartphone, with turn-by-turn directions 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.
