Notre avis

The Sigma Rox 4.0 GPS bike computer offers 30 functions for exploring roads and trails. With a 2.4-inch screen, you can display route directions or your training data.

Technology specialist

The Sigma Rox 4.0 GPS bike computer features GPS and Glonass reception to keep you connected on all your rides. Using the Sigma Ride app, you can configure your bike computer even more easily. It is equipped with a barometric pressure sensor that provides your precise altitude. This is also very handy for giving you accurate gradient readings. By pairing the Rox 4.0 with the Komoot app, you can set off on your adventure with route directions displayed directly on the screen. The red circle provides information such as the direction to take, the distance to the next junction, etc…

The Rox 4.0 is also compatible with electric bikes. It can display the assistance level you’re using, the battery level and the lighting mode.

ANT+ and Bluetooth connectivity allow you to connect most sensors, such as a heart rate monitor or a cadence sensor (but not power). Once you return from your ride, you can transfer your ride data directly to the Sigma Data Center app. With a battery life of around 25 hours and a recording capacity of 100 hours, it offers excellent endurance.

Simple to use GPS counter and relatively complete in terms of functions. Sigma app to download on mobile and then set up the different screens, relatively user-friendly. Satisfied with my purchase. (Translated review)

The use I wanted to make of this counter is actually simple. Like the ROX 10 which I was perfectly satisfied with: From Sigma data center on PC, load a route into the ROX and once the tour is completed, unload it onto the PC (no connection to Ride APP). No manual is provided with the device, the QR codes provided are just generalities. After struggling to understand how it works, I called Matériel vélo who kindly provided me with a video. I was finally able to complete a route guided by the device and have it recorded (I saw "recorded" on the device after pressing the right button), Impossible to unload it onto the PC, Sigma data center does not see it.... and of course, I do not see it on the device (where is it? the video does not mention it) VERY DISAPPOINTED, after another disappointment with the ROX 12 whose autonomy, not great new, dropped to 2 hours!

Nice design and the number of functions offered is enough for those who don't need mapping. Online user manual insufficient to manually set each screen. I will need to find someone more skilled than me to show me. (Translated review)
