All about bicycles, electric-assisted bikes, technology and safety in the press

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. 01/2015

On the safe side

On December 2 and 3, 2014 the German Association for Materials Research and Testing (DVM) held a workshop in Berlin on speed pedelecs. Product managers, testing engineers and experts of the association discussed the issue safety of speed pedelecs / electric bicycles. The preliminary conclusion: By using mountain bike components one is normally on the safe side.

For two days, the findings of a product segment were exchanged which had received little attention to that date: the speed pedelec. Why that? As these bicycles, i.e. the fast ones, are assumed to hold substantial potential in the future and as findings on the arising higher loads are certainly of good use to appropriately classify other types. Another expert workshop on electric mountain bikes was actually suggested right on the spot.


Dirk Zedler: CE-marking

On the occasion of the member’s general meeting of the German service and bicycle association (VSF) Dirk Zedler had held a lecture on the CE-marking. For this reason, we will only point out a few further aspects he mentioned in Berlin.

The operating instructions should for example also include the service life of a product as well as indications on how to dispose of the product. The correct interpretation of the term "safe" is no longer of major importance: The fact alone that there is a safer product does not mean that a product is unsafe. The existence of high-quality disc brakes is therefore not evidence for the fact that a HS 33 would be unsafe. In any case, however, a product needs to be marked properly. It must also show the supplier’s contact address; if this is impossible, the address must be indicated on the packaging.

The manufacturer is obliged to conduct spot checks and to maintain a book of complaints. Zedler reported from his experience cases where the service manager, the production manager and the product manager of a company had different knowledge about complaints and who had not found a way to bring their findings together. A simple Excel list where all parties involved would enter the complaints brought to their knowledge would do already. On the basis of such a list it would be possible to discontinue products with a high complaint rate.

Zedler pointed out once again the necessity of a risk analysis. In this connection, it has to be considered among other things that pedelecs ride faster by 5 kmh in the average than standard bicycles and are therefore exposed to higher loads.
