The high-contrast ROX 4.0 display's dimensions and extra-large numbers make it easy to read, even during a ride. The special Red Circle on the upper right corner of the display is highlighted in colour and offers bikers innovative, interesting display of training data. With the free SIGMA RIDE app for smart phones, the computer can be used to set individualised display views in just a few clicks – up to six screens can be configured, each with three values. The fourth value, current speed, is shown continuously on the display.

The ROX 4.0 bike computer can be positioned on the handlebars in a few easy steps. There is no need to mount cables or sensors. After it is switched on, the ROX 4.0 uses GPS and GLONASS to determine the biker's position within seconds. The user-friendly operation with three buttons enables you to start a bike tour right away.

A true highlight of the ROX 4.0 is the integrated air pressure sensor. It uses barometric readings to provide bikers with reliable information about altitude and to determine inclines and declines, allowing a precise recording of the track. You can also call up a graphical altitude profile on the ROX 4.0. The home altitude at the beginning of the tour is determined automatically from GPS or can be set manually.

The ROX 4.0 bike computer can be connected to the komoot app on your smart phone. Your smart phone can therefore stay in your pocket during the bike tour. Turn-by-turn instructions can be shown either as an arrow on the display or inside the Red Circle. This circle on the display is highlighted in colour and also shows the distance to the next turn-off as a coloured bar that gets shorter as the turn-off gets nearer. The number of metres to the next turn-off is also displayed next to the circle.

Thanks to ANT+ and BLE, external sensors such as power meters and speed, heart, and cadence sensors can also be connected to the ROX 4.0, so those who want even more data and even greater value precision can keep an eye on all of them if they wish.

The ROX 4.0 is e-bike-ready and can be easily connected to many e-bikes. Your GPS bike computer establishes a connection to the compatible e-bike system and shows the current assist mode, battery status, and light and other data on the display or in the Red Circle. However, the prerequisite for this is that the e-bike allows a connection with the ROX. This is possible with the current Shimano Steps motors, with Brose, with Panasonic, BMZ, Sachs or TQ.

The SIGMA RIDE app collects training data and transfers them via BLE from your ROX 4.0 to the smart phone. The most important data and statistics can be displayed in an organised form with coloured data fields and read quickly from the screen and assessed conveniently at any time.

The ROX 4.0 is delivered with the conventional GPS handlebar bracket. This disc can be mounted to the handlebars or stem with cable ties, and the ROX 4.0 can be twisted into it and fixed in place with a single click.
