This was reported by former Derby Cycle CEO Matthias Seidler at the opening of the Eurobike Show last August. The widespread criticism on the ADAC/Stiftung Warentest resulted in a joint campaign by Biketec (Flyer), Bosch eBike Systems and Derby Cycle to refute the test results and conclusions drawn by the two consumer organizations.


At a press conference next week Monday October 28th, the three companies, together with the German industry organization ZIV will point out the ADAC/Stiftung Warentest’s responsibility when publishing test results. Kurt Schär General Manager of Biketec AG, Claus Fleischer eBike-Systems division manager of Bosch, former Derby Cycle CEO Mathias Seidler and Siegfried Neuberger, GM of German industry association ZIV will hold both consumer organizations accountable for causing multi million euro damage to the e-bike industry and a lot of uncertainty among consumers.

‘Catastrophic’ test setup

After a thorough examination by certified testing laboratories, Biketec, Bosch and Derby Cycle firmly reject ADAC/Stiftung Warentest’s conclusions. In a joint statement the manufacturers announce that: “Stiftung Warentest pointed out that the result of their e-bike test was catastrophic. However, our results show that they used a ‘catastrophic’ test setup while their interpretation of their test results was also a ‘catastrophic’.”
