In our daily work as we deal with bicycle safety, technology and user manuals we come across lots of safety risks. The most frequent ones are published in articles of the leading German special-interest magazines TOUR – Europas Rennrad-Magazin Nr. 1, BIKE – Das Mountainbike Magazin Europas Nr. 1 and E-Bike – Das Pedelec-Magazin to make this information important for the sector accessible to a wider public.
For many years now the Eurobike Show Daily accompanying the annual international Eurobike Show has given us the opportunity to publish our perspective on major developments in the cycle industry in full-page articles.
We also speak regularly in independent lectures about all topics relating to bicycle technology and bicycle market. In addition, we are regularly cited by further special-interest magazines or trade journals as well as more and more by radio and television and in their media reports, which shows us that we are completely right with our information. The section NEWS informs you about the latest news from our specialist fields. The reports and publications of this section are listed chronologically or according to topics of interest.
In fact, the July issue of “test” included 15 eletric bicycles with low step-through which were put to the test. Seven bicycles were rated “good”, however five models were rated “inadequate”. The other three models were rated “satisfactory”. Test winner was "BS.1" by Flyer, leaving the "E-Manufaktur 7.9" by Victoria and the Decathlon modell "City Nexus" by Riverside behind. Test losers were Pegasus with their model "Premio ES F", Stevens with the "E-Courier Forma", Fischer with the "ECU-1603 ", Kettler with the "Traveller E Tour FL'' and the Aldi model "Alu-City-Elektrorad" by Hansa.
The reasons for the inadequate ratings were different. In the case of the Pegasus model it was criticised by the testers that the brakes were so weak “that they could not recommend the bicycle; during the endurance test the pannier rack broke”. Further weak points mentioned were an instable kick-stand as well as insufficient brackets on the pannier rack for the securing of the luggage.
For bicycle expert Dirk Zedler, however, things are quite obvious. “If there was one component in the cycle industry that didn’t cause any worries in the past 20 years, it’s Magura’s breakthrough hydraulic brake series HS 11' to 'HS 33’. ‘Mounting by screwing and forgetting’ is the motto. Among extreme and frequent cyclists it is therefore justifiably considered as carefree brake on the bicycle. Even Stiftung Warentest praised the hydraulic brake repeatedly and unexceptionally in the past, in order to devaluate two bicycles with this brake as “inadequate”. As serious tester they should have been obliged to find out possible causes (air in the system, dirty rims etc.) and eliminate them. As serious product testing organisation they should have been obliged to question the own inadequate stringency”, critises Zedler harshly.
In addition, Dirk Zedler is annoyed by the fact that cracks and breakages of safety-relevant components carried less weight for Stiftung Warentest. “In the past 23 years broken seat posts have been the predominant issue in our expert’s reports on material failure. This not only in terms of frequency, but also in terms of seriousness of the consequenes for the cyclist. Even without having seen the components, this procedure deserves in my opinion much consideration and is even contradictory to the actual bicycle claims in operation. A proof that the product testers and their testers are too far away from reality,” complains Zedler who states respectively: “German foundation for comparative product testing (Stiftung Warentest) cannot be taken seriously. This year’s results are again incredible.” In the case of the broken seat post Zedler refers to the Fisher model tested as “inadequate”. As regards the “Ecu-1603” Stiftung Warentest rated as follows: “Cheap pedelec. Breakages on both sides of the pannier rack and the broken seat post resulted in the devaluation. Unstable drive. Accelerates during the test under the influence of radio waves (e.g. amateur radio). Uncomfortable seating position. Pedal assistance starts with delay at the moment of setting off. Drive runs on long. Long charging. Reduction of the motor capacity even with semi-full battery. Long battery charging time. Low range.”
But the natives of Cologne also vent their anger out on the inadequate test result. Heinz Kettler GmbH as original distributor of the bicycle had a test according to which the saddle clamping meets the obligatory legal standards largely. In addition, ZEG had ordered further tests of the saddle clamp at Zedler-Institut as well as at TÜV Rhineland.“
