Eurobike Award - Winner 2018

The GPS bike computer combines innovative map navigation and a professional training system with a well structured operating concept and exceptionally powerful hardware. Large buttons and graphics on the touch display intuitively guide you through the menu. Like your smart phone, you can return to the start menu at any time by pressing the home button. The side and bottom buttons can be used to operate the ROX 12 when wearing gloves. A WiFi interface, the detailed map with quick and easy routing and numerous training functions make the ROX 12 perfect for training and touring.


Highlights of the Sigma Sport ROX 12.0 Sport

Innovative map navigation
There are various flexible routing options on the ROX 12, i.e. entering an address or coordinates, looking for a "Point of Interest" or simply marking a point on the map. You can also add intermediate destinations to an existing route or skip points during a ride.
A unique navigation feature is the "Draw my Route" function. If a line is drawn on the map by hand, the ROX 12.0 uses it to create a route. This can be saved as a track or started immediately. There are three options when a route is created. You may choose between the easiest, the recommended and the shortest route. Additionally, surface type preferences (bike paths, roads, unpaved trails) can be defined in the advanced section of the Sport Profile.
Maps of 20 European countries come preinstalled on the ROX 12.0 and additional maps can be downloaded for free.

Professional training system
The ROX 12.0 offers flexible training views and complete customization on up to six screens. Page layouts are suggested based on the number of values selected for each page (1 - 10). A total of 30 training views are available.
The computer can be customized based on each rider's unique needs. The central feature is the Sport Profile, which can be used to specify the training views, the sensors and the preferred routing options for each bike.
The ROX 12.0 provides the TSS®, NP® and IF®, in addition to the OCA and OCP values of a Rotor 2INpower. Plus, the ROX 12.0 SPORT will pair to transmitters via ANT+ and BLE therefore offering a huge variety of functions and information.

WiFi connectivity
With built in WiFi, rides can be loaded straight on to the ROX 12.0 from Strava, Komoot and GPSies. Routes from the DATA CENTER or the SIGMA LINK app can also be transferred by WiFi via the SIGMA CLOUD. As soon as you log into the training portals, the data is automatically transmitted by WiFi. In addition, the training data is immediately available in the SIGMA CLOUD and can be synchronized with the SIGMA LINK app and the DATA CENTER. The ROX 12.0 will also connect to your mobile hotspot if a WiFi network isn't readily available. But the ROX 12.0 does not communicate with the smartphone via Bluetooth.

E-Bike ready
With the firmware update 1.19.150, e-bike riders can now use the ROX 12.0 SPORT to display specific e-bike values ​​such as battery life, range and assistance level in addition to the usual navigation and training data. Via the ANT+ interface, the GPS bike computer connects to the Shimano STEPS E5000, E6100 and E7000 drive systems as well as ANT + LEV. E-mountain bikers benefit from the new features of the ROX 12.0 as well as e-leisure and touring cyclists on bike tours and bikepacking tours.

Powerful hardware
The bright display of the ROX 12.0 is perfectly designed for outdoor use. Whether you are riding in brilliant sunshine or on a cloudy day with low light, the screen is always clearly legible. The touch screen can also be used reliably in all weather conditions. For example, it can detect raindrops and will continue to function properly.

Personalized design
The ROX 12.0 can be customized with optional colored cases (optionally available).

Benutze den Rox für MTB Touren.. Navigation.. Bedienung.. ablesbarkeit des Display.. Super...
Nach 3x aufladen des Akkus hält er jetzt auch länger.Top Gerät.. sieht auch hochwertig aus!
Würde ihn jederzeit wieder kaufen!
Absolut Empfehlenswert
Der ROX 12 kommt bei mir sowohl beim Rennrad,- als auch zum Mountainbike/ Enduro fahren zum Einsatz.
Sicher ist der ROX 12 etwas teuer ist als vergleichbare Geräte, allerdings hat er auch mehr Features und wirkt von der Haptik wertiger. Außerdem ist er immer noch günstiger als die Geräte von Garmin.
Die Bedienung ist sehr einfach. Durch den schnell reagierenden Touchscreen Display und 5 bzw 6 zusätzliche Knöpfe am Gerät kann man sich einfach durch das Menü klicken. Auch lassen sich die Daten mit Hilfe des Sigma Data Centers leicht auswerten und nachvollziehen. Falls man dennoch nicht mit der Bedienung zurechtkommt oder noch mehr Features
Great bike computer, easy to use, excellent map drawing feature.
Fast perfekt. Anfangs war die Software total verbugt, jetzt läuft der Roxx sehr stabil. Wenn der Akku länger halten würde und bei Kartenupdates nicht immer der komplette Datensatz erneuert werden müsste, ja dann währe ich voll auf begeistert. Er hat bei mir schon über 500 Stunden GPS-Routing und Tracking auf dem Buckel bei jedem Wetter und der Akku zeigt keine signifikante Veränderung. Man bemerkt aber deutlich wenn zusätzliche Sensoren oder Routing genutzt werden. Da ist der Akku schon gefordert.
Akku nach einem Jahr durch
Im August 2018 habe ich mir den ROX12.0 gekauft, da ich Probleme mit dem Garmin hatte, der sich einfach nicht mit W-LAN oder iPhone verbinden wollte. Der Vorteil vom ROX war, dass alles über W-LAN läuft und Touren dann direkt z.B. auf Strava hochgeladen werden. Leider überwiegen nun die Nachteile: Das Ding ist sauschwer, relativ wenig Display im Vergleich zur Größe des Geräts, Routing eher so naja und vor allem ist der Akku nach dem einen Jahr echt durch. Nichtmal 5-6 Stunden hält er noch durch, ohne Routing!
Bin nun wieder beim Garmin 530 (nun funktioniert da alles) und etwas enttäuscht, dass der Sigma mit solch einem schlechten Akku nicht zurückgenommen wurde.
