For almost 40 years, Sigma has stood for competence, quality and excellent value for money in the fields of bicycle computers, sports watches and bicycle lighting.
The ROX 2.0 GPS bicycle computer is perfect for all those recreational athletes who use the essential advantages of a GPS bike computer and do not want to spend a fortune. Its large and easy-to-read display combined with easy operation make it the ideal companion for cycling tours. 14 functions such as display speed, distance and training time, navigation instructions and pairing to the e-bike are no problem for the ROX 2.0 bike computer. Thanks to the free Sigma Ride app, the current driving data can be tracked and analysed at any time via the Sigma Ride app on the smartphone.

Ready to use at any timeThe ROX 2.0 bicycle computer is positioned on the handlebar in a few simple steps. The installation of cables or sensors is superfluous. After switching on, the ROX 2.0 determines the position of the cyclist in seconds using GPS and GLONASS. In combination with the intuitive operation by two buttons, the bike ride can start immediately. |
Large displayThe high-contrast 2 inch display is very easy to read even while driving. A special Red Circle at the top right of the display is lined in colour and offers cyclists an innovative and exciting presentation of their training data. In combination with the free Sigma Ride app for the smartphone, individual display views can be set with a few clicks. |
Easy navigationThe ROX 2.0 bike computer can be connected to the komoot app on the smartphone. The komoot app then sends turning instructions to the ROX 2.0. These can be displayed as an arrow on the display or within the so-called Red Circle. The coloured circle on the display counts down the distance to the next bend by means of coloured bars. You get less the closer the cyclist comes to the turn. |

Smart notificationsSmart notifications also connect bikers to the outside world during the bike tour. The display shows information about incoming calls and messages on the smartphone. |
E-bike readyThe ROX 2.0 is e-bike ready and can be easily paired with many e-bikes. The GPS bike computer connects to the compatible e-bike system and displays the current support level, battery status, light and other data on the display or in the red circle. |
Convenient data evaluationWith the Sigma Ride app training data is transferred and collected via BLE from ROX 2.0 to the smartphone. The most important data and statistics can be clearly displayed with coloured data fields, read quickly on the screen and easily evaluate it. |
The ROX 2.0 comes with the standard GPS handlebar mount. This disc is mounted with cable ties either on the handlebars or stem of the wheel and the ROX 2.0 fixed by screwing in with one click.
The overclamp butler is available in the top mount set as well as accessories. It allows for perfect alignment of the ROX 2.0 bicycle computer even with short stems. This allows the computer head to be positioned in the middle of the stem at the height of the handlebar. The butler fits handlebars from 31.8 to 35 mm diameter.
