Stuttgart/Reutlingen – The German consumer advocacy group Stiftung Warentest has criticized the safety of pedelecs in an article on e-bike safety risks in its June 2013 edition. With regard to electrical safety, the test gave a number of pedelecs from different manufacturers poor ratings on the criteria of “radio interference,” saying that “they emit electromagnetic radiation.” The referenced EN 15194 standard for electromagnetic compatibility (EMC) defines tests and thresholds for the levels of electromagnetic interference and immunity emitted by the electrical components of e-bikes.

Bosch develops and tests pedelec drives in strict accordance with this standard. Independent, accredited institutes test these drive systems in various typical bicycle configurations. Bosch's drive systems all have EMC certification, which affirms that they satisfy the requirements for electromagnetic interference and immunity.

For technical reasons, the spread of electromagnetic waves is determined by the way the electric drive systems are mounted on individual bicycles. Different frame types and small variations in their construction can lead to slight differences in certain frequency ranges. The installation and testing of the systems is the responsibility of the bicycle manufacturers. Bosch provides the manufacturers with the EMC certificates and offers support with component installation. Testing institutes give final approval for the electromagnetic compatibility of completed bicycles to the manufacturers.

The magnitude of the critical deviations from thresholds as described in the Stiftung Warentest article can be ruled out for Bosch drive systems. There is no cause for concern about Bosch e-bike systems in everyday use.

Any inquiries about specific bicycle models should be directed to the relevant manufacturers.
