Why the SIGMA ROX Series Stands Out
The SIGMA ROX series gives you the freedom to choose exactly what you need for your rides. Each model is designed with a clear purpose – from simple GPS tracking to full navigation and structured training. No matter which ROX you pick, you get a clear display, long-lasting battery performance, and seamless e-bike integration. The handling stays intuitive across the lineup, while the features grow with your ambitions.
- Extensive lineup – Four ROX models with distinctly different features, from compact GPS basics to full navigation
- Seamless e-bike integration – Connects smoothly with Shimano Steps, Bosch, Bafang, Fazua, and more for real-time battery, range, and assist data
- Trusted German engineering – Nearly 40 years of expertise, with the ROX 12.1 EVO developed and built entirely in Germany
The SIGMA ROX Models at a Glance
The ROX lineup is easy to navigate: the ROX 2.0 gives you a lightweight entry into GPS tracking, the ROX 4.0 adds versatile features with barometric altitude measurement, and the ROX 11.1 EVO steps up with a color display and full training support. At the top sits the ROX 12.1 EVO, offering full map-based navigation and maximum connectivity. Which model suits you best depends on what you want from your rides – whether you're mainly recording data, structuring your training, or navigating new routes. Every ROX connects to the SIGMA Ride App, where you adjust settings, analyze your rides, and sync routes from komoot or Strava.
ROX 2.0 – Your Easy Introduction to GPS Tracking
The ROX 2.0 is ideal if you want reliable GPS ride data without breaking the bank. Its large 2.4-inch display shows 14 key metrics including speed, distance, ride time, and elevation. It’s compatible with komoot and delivers navigation cues straight to your display while your smartphone stays in your pocket. Thanks to its E-Bike Ready integration, you can pair the ROX 2.0 with compatible systems to see battery level and assist mode at a glance.
ROX 4.0 – Your Versatile GPS Companion with Elevation Tracking
The ROX 4.0 features more than 30 functions and gives you the flexibility to adapt your training and navigation to every ride. One standout feature is the integrated barometric sensor, which captures climbs, gradients, and elevation gain with impressive accuracy. Search & Go navigation helps you reach any destination quickly through the SIGMA Ride App, while track navigation guides you along imported routes from komoot or Strava. You can pair heart-rate, cadence, and speed sensors via ANT+ and BLE, and the large display stays clear even at speed. With up to 25 hours of battery life, the ROX 4.0 is a dependable companion for long days on your bike.
ROX 11.1 EVO – Your Advanced Training Companion in Full Color
The ROX 11.1 EVO is designed for riders who train with purpose and want clear insights into their performance. Its 1.77-inch color display shows up to six data fields per page, and you can use color accents to highlight key values for quick orientation during hard efforts. With more than 150 functions, it supports structured workouts, pairs with compatible power meters, connects to FE-C smart trainers, and integrates with electronic drivetrains such as Shimano Di2 or SRAM eTap. Track navigation keeps you on course, while smart notifications let you stay updated without reaching for your phone. And with up to 18 hours of battery life, the ROX 11.1 EVO is ready for those long training days.
ROX 12.1 EVO – SIGMA’s Flagship Navigation System, Made in Germany
The ROX 12.1 EVO is SIGMA’s full-featured navigation unit, developed entirely in Germany. Its 3-inch color touchscreen (240×400 px) delivers the best readability in the lineup, complemented by five side buttons for secure operation with gloves. You get true, map-based navigation with preinstalled European maps that highlight bike routes and trails. Plan routes directly on the device using address search, POIs, or the innovative Draw-My-Route function, which converts a rough line into a complete route. You can sync routes from komoot, Strava, or TrainingPeaks through the SIGMA Ride App. The ROX 12.1 EVO supports radar systems, controls smart trainers, and offers Crash Alert for automatic emergency notifications. Six preset sport profiles (road, MTB, gravel, e-bike, indoor) and up to 20 custom profiles make the 110-gram device your control center for all your bikes.
Key Technologies Behind the SIGMA ROX Series
SIGMA sets the ROX family up with proven technologies that give you reliability and easy operation across all models. At the core is GPS/GLONASS positioning – with Galileo included on the ROX 12.1 EVO – which accurately determines your location and delivers dependable speed and distance measurements. The barometric altimeter – starting with the ROX 4.0 – uses air-pressure changes for precise elevation profiles and detects gradients immediately. All ROX computers communicate with external sensors, smartphones, and e-bike systems via ANT+ and Bluetooth Low Energy – this dual connectivity makes the series especially flexible. The SIGMA Ride App brings everything together, linking your ROX to your smartphone for quick setup, route planning, and comprehensive ride analysis with graphic profiles and heatmaps.
GPS/GLONASS/Galileo – Precise Positioning Worldwide
Multiple satellite systems – GPS and GLONASS on all models, with Galileo added on the ROX 12.1 EVO – give you fast signal acquisition and accurate positioning, even in dense forests or narrow valleys. You get reliable speed and distance tracking without the need for additional sensors.
Barometric Altimeter – Precise Elevation Profiles
The integrated barometric altimeter – available from the ROX 4.0 upward – measures elevation changes more accurately than GPS alone. You’ll see gradients in real time, record exact elevation gain, and get a clearer sense of your performance on hilly routes. For planning routes or analyzing training sessions, this level of detail makes a big difference.
E-Bike Ready – Seamless Pedelec Integration
All ROX models connect with common e-bike systems such as Shimano Steps, Bosch, Bafang, and Fazua. You’ll see battery level, remaining range, your current assist mode, and even shift recommendations directly on the display – without needing a separate e-bike head unit. After your ride, the SIGMA Ride App shows you how many kilometers you covered in each assist mode using clear, color-coded views.
SIGMA Ride App – Central Control and Analysis
The free SIGMA Ride App for iOS and Android is your control center for all ROX computers. You can set up sport profiles, customize your data fields, import routes from komoot, Strava, or TrainingPeaks, and analyze your rides in detail with charts and heatmaps. Syncing works quickly via Bluetooth, and your data is stored in the SIGMA Cloud so it’s available across all of your devices.
ANT+ & BLE Connectivity – Maximum Sensor Flexibility
Dual connectivity via ANT+ and Bluetooth Low Energy supports nearly every sensor you might use: heart-rate straps, speed and cadence sensors, power meters, electronic shifting systems like Shimano Di2 or SRAM eTap, and even radar systems on the ROX 12.1 EVO. This flexibility makes the ROX series an open, adaptable platform that grows with your ambitions.
