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.

Reader’s question: "Helmet aging"

Half-life period for helmets

A notice of the German traffic patrol organisation (Deutsche Verkehrswacht) states that cycle helmets must be replaced after two to three years at the latest, as they no longer provide protective effects. Is that true?

Reply given by graduate engineer Dirk Zedler, bicycle expert

The hard foam inside a helmet ages. The helmet should be replaced every two to three years depending on storage and treatment, at the latest, however after five years. After a crash the helmet must be replaced immediately. Unvisible cracks or deformations affect the protective effect. To lengthen the service life you should clean your helmet only with water. Do not use aggressive agents and store the helmet in dry and dark conditions.
