What our customers are saying about Sigma ROX 4.0 Endurance cycling computer

This bike GPS computer boasts spectacular, long-lasting battery life, lasting for days on a single charge. A great cycle computer for amateurs, it offers quick satellite connection and excellent Komoot integration for route navigation. The simple trace line is useful, and it connects quickly to e-bikes and external sensors. While the interface takes getting used to and some minor distance inaccuracy is noted, it´s a reliable device with a built-in temperature sensor and a great price-quality ratio

Great gps for bikes

2025/03/06

roberto

Excellent GPS for bikes, essential in its functions but more than sufficient for amateur and cycle tourism use. Not very intuitive to use Sigma RIDEAPP and Sigma DATA CENTER. Excellent interaction with Komoot. Quick to turn on and hook up to satellites. Some delay or advance in signaling turns and in correctly measuring kilometers: on 70 km effective (measured with other GPS) the Sigma marks me 75 km. Apart from this the only negative point is that you can only enter one route at a time. Spectacular battery life: after three days of travel, following and recording a track I still have 60% charge left! Ultimately an excellent purchase with an excellent quality/price ratio.

Good "simple" gps bike computer with long battery duration

2025/02/17

Tristan

Product works well, and the simple trace line to follow the route is more usefull then you would think, if you have a phone or something else nearby as a backup for diffivult situations. Battery duration is very long, as advertised. Temp sensor builtin is also a nice extra. Some things could be made more logically: the device knows and announces it is moving, but it can't autostart an activity. Long press right to save an activity but short middle press to start one can sometimes be a bit confusing. The android app tends to forget it's connections to komoot and strava now and then.
