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 during their rides, allowing them to focus on what really matters: 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, with a diagonal of 2.4 inches and extra-large digits, is very easy to read even while riding. A special red circle in the top right corner 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 can be configured, each showing three values. Current speed and time are permanently displayed.

Ready to Go Anytime

The Rox 4.0 bike computer can be easily mounted directly on the handlebars with just a few 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. Upon switching on, the Rox 4.0 quickly determines the cyclist's position 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.
