E-bike compatibility

The ROX and EOX series is e-bike ready and can be easily connected to many partner e-bike systems. When your device is connected, the bike-specific values will be displayed.

Check whether your e-bike is compatible with your SIGMA.

Every e-system has requirements that must be considered to ensure compatibility with SIGMA components. You can tell which system your e-bike is equipped with from the brand name on the motor, the handlebar control unit or in the technical information of your e-bike.

CHOOSE YOUR E-SYSTEM and check compatibility.

Your e-bike with MAXON BIKEDRIVE AIR is compatible with the SIGMA E-Bike Service (BLE) and ANT+ LEV. When searching for e-bikes, you will be presented with two connection options. In this case, please choose the connection with “MAXON BIKEDRIVE AIR” (BLE) because we can give you more information via this interface.
