Sigma Sport ROX 4.0

Rox 4.0 - GPS Bike Computer with Altimeter

The Rox 4.0 GPS bike computer supports cyclists with its 30 functions and user-friendly design, allowing them to focus on what matters most: the joy of cycling. The extra-large display reliably shows data such as altitude profile, speed, distance, and training time. Navigation prompts and connectivity to e-bikes and external sensors are standard features of the Rox 4.0 bike computer. Thanks to the free Sigma Ride app, current ride data can be tracked and analyzed at any time.

Outstanding Display

The high-contrast display is very easy to read while riding, thanks to its 2.4-inch diagonal and extra-large digits. A special red circle at the top right of the display is color-coded and provides cyclists with an innovative and exciting representation of their training data. In combination with the free Sigma Ride app for smartphones, individual display views can be set up with just a few clicks - up to six screens with three values each can be configured. Current speed and time are permanently displayed.

Ready to Go Anytime

The Rox 4.0 bike computer can be positioned directly on the handlebars with just a few simple steps - completely without cables and sensors. If desired, the Rox 4.0 can be paired with additional sensors to measure speed, heart rate, and cadence. Once turned on, the Rox 4.0 determines the cyclist's position in seconds using GPS and GLONASS. Combined with intuitive operation via three buttons, the bike ride can start immediately.

Barometric Altimeter

A true highlight of the Rox 4.0 is the integrated air pressure sensor.
