According to the product specialist

Pros
When connected with the Komoot app, the Sigma ROX 4.0 gives you turn-by-turn navigation during your bike ride.
The Sigma ROX 4.0 can be connected to external cadence, heart rate or power meter sensors.
The high-contrast 2.4 inch screen makes your data easy to read in all weather conditions.
The ROX 4.0 is E-bike ready; when paired with a compatible system it can display your battery status, radius and more.
With the addition of GPS, this bike computer allows you to save accurate workout data, and even gives you navigation options.
Easy route planning via your phone with GPX and Strava support.
Clear turn-by-turn navigation and automatic route recalculation.
Clear and simple screen with all essential ride data.
Mountable on any bike and, weighing 25 grams, a lot lighter than most other bike navigators.
Sustainable green choice!
Cons
For navigation, the Sigma ROX 4.0 must remain connected with your smartphone and the Komoot app.
The ROX 4.0 does not offer map navigation, which more expensive bike navigation systems do.
Cannot be paired with other sensors, such as a heart rate or power meter.
Due to its more limited functionality, it is less suitable for the performance-oriented cyclist.
