ROX 12.1 EVO: GPS bike computer with map navigation
The user-friendly GPS bike computer is a bike navigation system for anyone who wants to discover the world.
On forest floor, gravel, or asphalt, the compact (110-gram) bike computer´s multifaceted map navigation functions identify the best route and get the cyclist to his destination reliably.
It records extensive data for each ride and takes training to a new level.
When combined with the free SIGMA RIDE app for iOS and Android, it can assess tours anywhere, anytime.
Made in Germany innovation.

Highlights
- Bike-optimized map material
- The ROX 12.1 EVO comes with lots of pre-installed country maps.
- The bike computer is ready to go as soon as it is unpacked!
- A SIGMA-specific map display ensures that cyclists can find their way around.
- The maps highlight bike paths and trails, and always take them to the best track, no matter where they are or what bike they are using.
- The compressed maps require little storage, so a number of areas around the world can be stored permanently.
- More maps and regular updates can be downloaded with WiFi free of charge.

Innovative map navigation
- Simply enter an address or routing to a point on the map or a point of interest (POI) – the ROX 12.1 EVO´s navigation possibilities are limitless.
- The ROX 12.1 EVO uses home navigation to always find the quickest way home.
- The Back-to-Start function takes cyclists to the beginning of the tour − on the same track if they want.
- The multifaceted navigation functions can be used without the ROX being connected to the internet or a smart phone, of course.

Smart routing
- Cyclists can decide for themselves the criteria the route should meet.
- They can choose among the recommended route, the easiest, and the shortest.
- The altitude profile is also displayed for each.
- Route preferences (bike paths, main roads, dirt roads) can also be specified individually for each sport profile.
- If cyclists spontaneously deviate from the suggested track, the ROX 12.1 EVO will quickly plan a new path to the destination − including re-calculating distance, altitude profile, and predicted arrival time.

Navigation with turn-by-turn instructions
- During navigation, the three-inch display shows the track and turn-by-turn instructions.
- A pop-up window with an acoustic signal indicates the next turn.
- The distance to the next turn-off and the street name are also displayed.

Load tracks and plan tours easily
- Tracks are imported from portals such as Strava and komoot or as a .gpx file into the free SIGMA RIDE app.
- Tracks can now be called up in a clear format at any time, synchronized with the ROX 12.1 EVO, and started.

Connecting to external sensors
- ANT+ and BLE make it extremely easy to reliably connect the ROX 12.1 EVO to external sensors for measuring speed, cadence, and heart rate.
- It can also be paired with other sensors such as electronic gear changing systems, radar, smart trainer, or power meter (TSS®, NP®, IF®, OCA, or OCP).

E-bike-compatible
- The ROX 12.1 EVO can be paired easily with many e-bikes and show specific values such as range, battery level, and support level, depending on the e-system connected.
- The display can also show the gear change recommendation for the motor, saving the cyclist energy and battery charge.

Optimally networked with third-party providers
- Routes can be planned on third-party portals such as komoot and loaded directly to the SIGMA RIDE app on the ROX 12.1 EVO.
- Successes and special experiences can be quickly shared to social media platforms such as Strava, komoot, TrainingPeaks, Facebook, Twitter, and WhatsApp.
- Apple Health is integrated, so users of the SIGMA RIDE app for iOS can also share their routes and training values there as well.

Training assessment with the SIGMA RIDE app
- Besides quick on-device assessment, the free SIGMA RIDE app for iOS and Android can assess your tours in detail – anywhere, anytime.
- The app transfers data from the ROX 12.1 EVO to a smart phone via BLE, collects training data, and shows statistics for the last few weeks, months, or even years.
- Graphic profiles and heat maps visualize performance on the route, making outlying values easy to detect.
- The RIDE app is a smart companion for the ROX 12.1 EVO and helps adjust the device more conveniently, manage tracks from various platforms, and transfer them to your ROX 12.1 EVO.

Smart features
- The Crash Alert built into the ROX 12.1 EVO automatically detects a fall and gives the rider 30 seconds to confirm that everything is OK.

I bought this cycle computer because it is easy to use unlike Garmin. Garmin is reviewed by everyone and many Italians but the Sigma Rox 12.1 by no one so always going against the grain I decided to try it and I must say that it has nothing to envy the Garmin and costs less. The Sigma App works well and is easy to use with Komoot or Strava and it is easy to transfer the routes. I recommend

For 300 euros it's ok, but considering how much it used to cost, it's a bit surprising. I don't know if the sensor functions work properly, the thermometer distorts significantly downwards at lower temperatures (for example, at temperature 0 it shows -3.8) - I liked the ROX series mainly for the thermometer, which worked perfectly in 4.0, and here - I think the manufacturer did not managed to correct the temperature in relation to the own heat generated by the meter itself, perhaps this can be corrected by the firmware, but there has been no update for several years. Therefore, I do not trust the built-in blood pressure monitor. As for speed and time indications and other GPS data - there is no problem here, although the maps are not very accurate and the position indicator is not very visible, this should also be improved by the manufacturer, we will see, it would be best if the user could decide on the size, color and shape of the "cursor", had a choice of several options. As for external cadence and speed sensors - they connect without any problems, but sometimes disconnect when standing still and sometimes you have to manually refresh the connection.The visibility of the screen is correct, the backlight is very good, it may be worth turning it on permanently, because the battery should be enough for the whole day of riding, and an undoubted advantage is that the device can be charged, e.g. from a power bank, during normal operation.

Dominique

Is it compatible with the sensors of the Sigma Rox 11.1 computer? Thank you.

Answer of Dimitar

Hello. I haven´t had Sigma 11.1, but I think they´re compatible because they´re the same generation. 12.1 came out a few months later.
