Providing you with reliable information about altitude and generating a precise record of your route.

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 in seconds. Along with the user-friendly operation with three buttons, this allows a bike tour to be started right away.
