Reviews over the

Sigma ROX 12.1 EVO GPS

Still has a lot to learn

Pros & Cons

Great bike navigation easy to use on my road bike and e-bike thanks to the two supplied mounting brackets. In the beginning it was a bit difficult to transfer cycling routes via Komoot but now it goes quite well. Tip: set everything properly at home before cycling and not while cycling for your own safety and for other road users!

Pros & Cons

Within a short time you have mastered the controls. Compared to my older Garmin, the ease of use is many times better.

Pros & Cons

Fine complete device, with strong navigation;various options, easy with Komoot and fast. Price-quality is top. Battery life generously a day. The touchscreen makes operation easier than competing devices that do not have it. In addition, the price is friendlier than US competitors.

It's OK

I am very excited about the Rox 12.1 EVO bike computer. It has unlimited screen set-up options and, like the accompanying app, is incredibly user-friendly. The maps are updated via WiFi (at home). The computer has crash detection functionality and provides you with smart notifications. Top turn-by-turn navigation and every conceivable sensor can be linked. Data exchange of activities can be automatically uploaded to the well-known platforms like Strava, Komoot etc. Routes can be easily exported from Komoot, for example, to the device. Only downside I could discover is that the screen does not handle rain very well, but this is solvable by locking the screen and using the buttons. The battery does not last as long as those of the competition, but say honestly who sits on the bike continuously for more than 14 hours? This bike computer actually has all the functionalities you can expect as an avid cyclist these days and can actually do everything the competition (Garmin Edge 1040 or Wahoo Element) can also do, but at a much more friendly price.

Pros & Cons

I was already very fond of the Rox 12.0 only of that the battery life was a downside, as it deteriorated quite quickly. So far, the Rox 12.1 evo performs much better and is still more compact with the same screen size. The Sigma Ride app is very user-friendly and can be connected to the cycle computer via Bluetooth, through this app you can also link Komoot / Strava. Planned routes are easily transferred to the bike computer and, vice versa, route data and statistics of a driven trip are sent to the app. It is also possible to customise the layout of the bike computer in the Sigma Ride app. The ability to put the device into power-saving mode during use is a huge improvement. While navigating you will then get a sound signal and the screen lights up when you approach a turn, when the turn is taken the screen automatically switches off again. This extends battery life should you really need it. Gps works fine, even in the woods, route instructions are clear and easy to read on the large screen. I use it while mountain biking / gravel biking and during (long) trips on the road bike, the device did not let me down and the battery life was still more than sufficient without having to use the power saving mode. The sensors (speed / cadence) from the Rox 12.0, which I still had on the bikes, also work perfectly on this bike computer and are quickly found and paired.

Pros & Cons

Easy to operate, easy to read while cycling really great to use. Price presentation ratio couldn't be better.
