Sigma rox 4.0
Juan Alberto - 03/04/2023
Simple but good but I have a connection problem with my mobile, I don't know if it is due to the new update. It constantly disconnects and connects and there are times that I have to reset again to reconnect and pair with the mobile. To record or follow routes, it goes well at all times, it tells you if you are going well or off the route
Perfect

excellent gps great functionality
Good basic gps.
Marcelo - 03/07/2022
Low price, German Sigma quality. It brings three basic modes for the information of the route on the screen, you can save and view data in the Komoot app, when synchronizing with the mobile. Useful for the amateur cyclist and the cadence sensor could be purchased separately, to further complete the data. The speed is marked by default, the GPS connects quickly and registers with good precision. It has a backlight and a full charge lasts for approximately 4 full 2-hour rides and still has a charge left. Good screen, clear, legible and the device weighs very little. I bought the pack with a heart rate band that comes with a battery included, but I think it's expired, because it doesn't sync to the GPS (I have to try a new one). It comes with a USB cable and butler Sigma (size suitable for thick MTB handlebars), which I had to replace with another brand, due to the thinner size of my handlebar.
Отличный велокомп
Andrii - 08/06/2022
Заказывал доставку в Украину. Товар пришел в течение 2-х недель. Велокомп полностью соответствует описанию. 100% оригинал. Я доволен, получил то что заказал. Плюс тут существенно дешевле, даже с учетом доставки, чем в веломагазинах Украины.
Excellent sigma 4.0

ROX 4 Review
Clarence - 04/03/2022
the product arrived overseas approximately 3 weeks from ordering. the product was well presented and easy to attach to the bike. the setup took little time. oddly the “off” function was not as intuitive as i thought. i found the screen prompt ,and arrow confusing but after some failed attempts i got the routine. overall rox 4 is solid interacting with my phone at an affordable price.
Great computer

A good bike computer, the only thing you need to understand well is which version you are taking, now we will drive
Cool. sigma rox 4.0
Daro - 09/02/2022
Fast shipping. Product as described. Professional approach to the client.
Another Strong Offering from Sigma
Lloyd - 06/02/2022
I bought the Rox 4.0 because I though my 10 year old Sigma Rox 9.0 had died. Turns out it just needed a fresh battery (d'oh!). The Rox 4.0 has a number of advantages over the 9.0 in that it's much more customizable, and has more features including GPS. It's very easy to set up either manually or through the use of the SigmaRide app, and very simple to use. As a bonus it was about half the cost of the Rox 9.0. If it lasts as long as my old Sigma, I'll be very happy. Kudos to Bikeinn for fast and efficient shipping.

Design is beautiful. Operation is not quite as intuitive as I would have liked. The operating instructions could also be a bit longer and more detailed. Create a proposal for a longer operating manual and make it available online. I think it's a shame that you can't save any gpx routes on the device. In order to use the navigation function, the mobile phone must always be connected to the device. This is of course annoying because you don't save a battery.
Very good recording and evaluation
Ralf - 25/09/2021
The presentation of the information is very good, and the app also fits. I finally know how much / little I drive, what heights I climb and what kind of pulse I have. Not so nice: very sensitive GPS, there is an immediate warning at underpasses, with a lot of trees the speed is not always right. The app would like the location on the mobile phone permanently, not only when using the app.
Awesome computer
Akshat - 22/09/2021
In this range it's awesome cycling computer. It has all those function which is necessary. Mounting is easy too. Once your hands adjusted to its button it works like charm. Also I have got this delivered at my door step in India.
Great product
aldo - 15/09/2021
Nice product at an affordable price. Congratulations also for shipping within the indicated times.
Great device, somewhat poor operating instructions
Roland - 15/09/2021
At the beginning I was very skeptical because I couldn't couple the app and the HR sensor. Then I contacted the Sigma service and they were very quick with the answers and tips, so that everything is now running as it should. 1 star trigger for non-intuitive operation and concise operating instructions
Good
Erioli Pietro - 12/09/2021
Good product but with a poor Italian translation especially in the coupling with smartphone and HR sensor, Bluethot not exceptional
Full control of routes
Raquel - 07/09/2021
Perfect to know both where you are going and then to be able to make a good analysis of the training
Excellent
