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.
When automobile engineers develop a new car, they nowadays already know before the first serial production what will happen to the passenger cell if the car crashes against a fixed obstacle at 50 kilometers per hour. An exakt knowledge of the material properties allow for computer simulations to be created which mirror reality almost par for par. With bikes, this is unimaginable.
The diamond frame costruction has been existing for more than 100 years indeed. But up to now, we have come to know only vaguely which forces impact on the individual components of the bike. This didn't matter when bikes still were so heavy and robust that they often outlived their owners. Today, the road bike - just like any other object of utility - is subject to trends and tendencies much more than it used to be - and an important trend is low weight. Only very few manufacturers, however, calculate before serial production, how much material is needed where in order to build a light, but nevertheless safe bike; most of them just try until the compromise between weight and qualities like stiffness and stability roughly fits. But just roughly: There are definitely far too many bikes on the road whose low frame stiffness at least irritates their riders or - worse - brings them into trouble. And there are far too many documented cases of breaking stems, handlebars and seat posts.
