Medienberichte und Publikationen rund um Fahrräder, Pedelecs, Technik und Sicherheit

Die häufigsten Sicherheitsrisiken, die uns in der täglichen Arbeit rund um Fahrrad-Sicherheit, -Technik und -Bedienungsanleitungen auffallen, publizieren wir auch in Artikeln in den führenden Fachmagazinen TOUR – Europas Rennrad-Magazin Nr. 1, BIKE – Das Mountainbike Magazin Europas Nr. 1 und E-Bike – Das Pedelec-Magazin, um diese für die Branche wichtigen Informationen einer größeren Öffentlichkeit zugänglich zu machen.

Auch die Eurobike Show Daily, Messezeitschrift der jährlich stattfindenden Eurobike Show, gibt uns seit vielen Jahren die Möglichkeit, unsere Sicht auf wichtige Entwicklungen in der Fahrradbranche in ganzseitigen Artikeln auszuführen.

Darüber hinaus sprechen wir regelmäßig in unabhängigen Fachvorträgen über alle Bereiche der Fahrradtechnik und des Fahrradmarktes. Auch weitere Fach- bzw. Branchenzeitschriften sowie immer häufiger Radio und Fernsehen zitieren uns in ihren Medienberichten und zeigen uns, dass wir mit unseren Hinweisen genau richtig liegen. In der Rubrik AKTUELL erfahren Sie laufend alle Neuigkeiten aus unseren Fachbereichen. Diese Berichte und Publikationen sortieren wir für Sie chronologisch bzw. nach Interessensgebieten.

BIKE 05/2014


"In the mid-nineties the thin aluminium mountain bike flatbars weighed 300 grams in the beginning and then all of a sudden less than 150 grams. For us as experts broken handlebars were part of the day-to-day business.

Subsequently, the manufacturers added about 50 grams and then levelled out step-by-step at 170 grams, a weight which was considered as acceptable. These dark times of careful approaching are fortunately behind us. However, not all suppliers in design and testing have kept pace with the rapidly developing sport. Today’s loads are clearly higher and the number of riders exploring their limits has increased. Handlebar breakages in the area of the lock-on grips, brake lever clamps or stem failure, as created by the test stands on some of the handlebars tested still happen in practice. By testing only according to what is required by the standard does provably not result in safe and durable products. For us, handlebars must be designed in a way to withstand for example regular events, such as falls.

The test results show that the best handlebars remain very long unaffected even by the strongest loads. It is certainly amazing for many people that of all things carbon handlebars show highest durability. The potential of the material is huge, the risk of making mistakes, as well. Carbon handlebars are fabricated by manually inserting the fibre mats. Therefore, each single component has to be checked for quality at the plant, otherwise risky products come on the market. Everybody who chooses weak handlebars with a large variance from the test field in addition should replace consequently after every fall for safety reasons!"

Editorial: Dirk Zedler’s institute for bicycle safety is considered one of the best addresses when it comes to laboratory tests. Even the German foundation for comparative product testing (StiWa) has meanwhile come to this conclusion. For this reason they visited the bicycle expert in the Swabian city of Ludwigsburg. Zedler had directed massive criticism against StiWa for their Pedelec test and presented on this occasion realistic alternatives to the StiWa testers. Our handlebars laboratory test was also performed at the Zedler institute, as for BIKE the practical relevance of the test procedure takes top priority, too.
