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.
