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.

THESE ARE THE TESTING METHODS OF BIKE

To achieve the most realistic load possible BIKE tests with load spectra recorded in practice. All in all three handlebar/stem combinations per manufacturer had to prove themselves.

MULITLOAD AND EN-TEST

Three handlebar/stem combinations respectively had to show how safe they are in two different tests carried out at the independent test institute Zedler. We started with the test according to the DIN EN 14766 standard. Although this is mountain bike standard, it no longer meets the requirements of today’s riding style and loads. The other two test samples had to undergo a finely mixed Multiload test (see picture) based on extensive real data. For the best practice-oriented simulation possible additional fittings, such as brake levers and lock-on grips, were mounted according to the manufacturers’ specifications. The graphics below shows the individual test blocks which every handlebar/stem combination had to undergo. The loads are divided in in-phase and out-of-phase situations with various forces. Every 4000 load cycles were followed by four high out-of-phase loads simulating hard landings or falls. The test stopped with the breakage of the handlebars or the reaching of one million load cycles.
