All about bicycles, pedelecs, 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.

BIKE 01/2016

THE NEW TEST

Mountain bike technology has developed rapidly over the past years. It’s high time for us to modernize the testing system – with brand-new test stands and harder criteria.

"Offshore racer for hot bumps", "nervous greenhorn for brave cowboys" or "off-road racer for grandpa and grandchildren". When we developed the first test methods for mountain bikes 25 years ago, the test letters often ended with a flippant joke. Today, nobody will allege that a BIKE test is flippant. For years, our testing system has been setting international standards; many manufacturers and other media tried to copy our testing methods for the determination of stiffnesses, chassis efficiency, sitting comfort and paint quality. After all, BIKE tests led to an improvement of mountain bikes; no industry insider will contradict. With this issue we go another step forward: Curtain up for the BIKE test V2.0. For 2016, we upgraded our laboratory, tuned up testing methods, added new criteria and adjusted ratings. With the new testing system, we place more importance than ever before on the benefit of a bike for the customer spending a lot of money for his sports equipment and expecting maximum quality. The key issues are "usability", guarantee or quality, but we'll revert on that further below.

That’s new

Future BIKE tests will continue to be composed of the elements laboratory (objective) and practical riding (subjective). Our internal test centre was upgraded with state-of-the-art-and-technology test stands. The new stiffness test stand developed by our partner Zedler-Institut für Fahrradtechnik und -Sicherheit GmbH also includes a function for the measurement of the characteristic curves of forks and rear frames as well as the recording of the wheel trajectory curve. Due to these three functions, this brand-new machine was internally dubbed "Triceratops". We still determine the isolated value of the frame stiffness, without wheels and fork. The value is added to the points table, criterion riding stability.

THE TEST MONSTER CALLED TRICERATOPS

One for (nearly) all: Centrepiece of the new BIKE test is the test stand developed by Zedler-Institut, internally called: Triceratops. It not only determines the frame stiffness, but also measures accurately the characteristic curves of fork and rear frame in the following step.

1. SPRING CHARACTERISTIC CURVE We determine spring travel and characteristic curve of each bike on ourselves. It provides data about the chassis characteristics as well as the actually usable spring travel. The new test stand from our technology partner Zedler writes the characteristic curve documented in the test letter and also records the wheel trajectory curve. This helps analysing the character of a rear frame system.
