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

The most common safety risks that we come across in our daily work around bicycle safety, technology and operating instructions are also published by us in articles in the leading German special-interest magazines TOUR (Europe's road bike magazine no. 1), BIKE (Europe's mountain bike magazine no. 1), MYBIKE and EMTB in order to make this information, which is important for the industry, available to a wider public.

For many years now, the Eurobike Show Daily, trade fair magazine of the annual Eurobike Show, has also given us the opportunity to publish our view of major developments in the cycle industry in full-page articles.

We also speak regularly in independent expert presentations about all areas of bicycle technology and the bicycle market. In addition, we are quoted by further special-interest magazines of the industry and the trade as well as increasingly by radio and television in their media reports, which shows us that we are spot on with our advice. The section "News" informs you about the latest news from our specialist areas. The reports and publications of this section are listed chronologically or according to areas of interest.

"There’s nothing that has not yet broken", Dirk Zedler

Together with his institute for bicycle technology and safety, Dirk Zedler has been testing all kind of bicycle components for 20 years now. He has been writing for the Tour magazine for exactly this period of time.

TOUR: Looking back on two decades as bicycle expert, what stays in mind?

Zedler: Within this period of time I gained experience of lots of accidents with severe consequences, from people who became dependent on care to cases of death. And there is nothing on the bicycle that has not broken on these occasions: Frames, forks, stems, handlebars, pedal axles, cranks, inner bearings, seat posts, saddle rails – maybe brake levers not yet.

Broken parts with brutal consequences: does this mean a personal stress for you?

There were indeed some difficult cases. You see that one of the components has a problem. But you as an expert are not allowed to issue a warning or to publicize it. Sometimes it is indeed an outrageous injustice. I still know some manufacturers who sit problems out.

Can you still enjoy road racing at all?

In the 90ies it often made me sick. I knew that many manufacturers were working on a trial and error basis and that there was no serious testing of their products. For many years, however, I’ve been road racing with passion, as I know that the knowledge of the bicycle sector has grown a lot. Meanwhile, lots of manufacturers have installed development teams and become much more professional, all in all we’ve experienced a significant leap forward in quality.

Is the bicycle purchased in a DIY construction market as bad as its reputation?

In most cases, these bicycles are not used for a very long time. Therefore, they often do not reach the critical limit of failure. As a matter of fact, this is completely different with an expensive sports bicycle.

How did your cooperation with the TOUR magazine start?

As a bicycle expert I knew which components were bound to make problems or fail. I had a lot of fun in developing together with Robert Kuehnen ideas for test methods and test stands. We only just kept everything under constant review and thought about different test procedures. 

The three most important tips for more safety?

No clincher tyres without rim tape, no carbon part assembly without carbon assembly paste and torque wrench and the servicing of your bicycle by your bicycle dealer once a year. I treat my carbon bicycle like a raw egg. When you’ve done everything correctly, carbon is a really reliable material!
