The ROX 4.0 Endurance from Sigma is an advanced bike computer, designed for ambitious cyclists looking for solid support in training and navigation. The Endurance version has a significantly longer battery life, making it the perfect choice for long-distance adventures and intense training sessions.
Equipped with more than 30 practical functions, the ROX 4.0 comprehensively meets the needs of every lover of two wheels. Intuitive operation and a clear interface allow you to focus fully on the ride, and the large, easy-to-read display provides easy access to the most important information: speed, distance covered, riding time and altitude profile.
With its intelligent navigation function with dynamic route changes, full compatibility with e-bikes and support for external sensors (e.g. cadence or heart rate), the ROX 4.0 is a versatile companion for any tour. Thanks to the built-in altimeter, the device precisely monitors changes in terrain and allows you to track even the most demanding climbs.
One of the biggest advantages of the meter is the ability to graphically present the route profile – it is a tool that allows you to optimally plan your effort while riding and better prepare for the next sections.
Simple to use, feature-rich and reliable in all conditions, the Sigma ROX 4.0 Endurance is a bike computer that will meet the needs of weekend cyclists and hardcore performance cyclists alike.
Simple and effective
Mounting the ROX 4.0 bike computer on the handlebars is quick and easy. Without the need for complicated cables or sensors, you can start your ride in just a few simple steps. When switched on, the ROX 4.0 instantly determines your location using GPS and GLONASS technology, ensuring accurate route tracking.
The computer is very intuitive to use thanks to two buttons, which allows you to quickly adjust the settings before a bike trip. In the Sigma Ride app, you also have the option to personalize the way your data is displayed, giving you the optimal conditions to monitor your ride.


Routes in the meter
The navigation function in the Sigma Ride app allows you to upload a pre-planned route. All you need to do is create a route in Sigma Data Center or on a selected portal (e.g. komoot, Strava) and then import it into the application. Once you have started a route in the app, you can go directly or save it for later use on your bike computer. This makes route navigation simple and does not require a smartphone connection.
Training Analysis
With the Sigma Ride app, you can easily transfer training data from your ROX 4.0 to your smartphone using BLE technology. Once the data is transferred, you can store it on your smartphone and quickly adjust your favorite display views. Using the Live function in the Sigma Ride app, you can track and analyse your most important data and training stats in real time on your smartphone screen. This advanced functionality allows you to conveniently monitor your progress and plan your workouts efficiently.


When you're high
One of the main advantages of the ROX 4.0 bike computer is its built-in altimeter. With barometric measurements, it provides precise altitude data, allowing for accurate monitoring of ascents and descents and recording of the route. In addition, ROX 4.0 offers the option of displaying a graphical elevation profile, which facilitates terrain analysis. The starting altitude can be automatically calibrated via GPS or set manually, ensuring accurate measurements on each trip.
