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.

Creating facts

Trust is good, control is better. All electric mountain bikes undergo extensive testings in the laboratory. There is no final picture available until the laboratory results have been compared with the findings of the practical tests.

Hightech testing systems by Zedler

At our editorial office in Munich we make the most successful bicycle magazines in Europe: BIKE, TOUR, FREERIDE, TREKKINGBIKE and E-BIKE set the standards in their specific category. Engineers and bicycle mechanics work in our test lab to generate all relevant measurement data from a phalanx of hightech test stands. With this know-how as basis we could make EMTB. First, however, we had to redefine some points:

The average weight of a regular mountain bike is no more than about 12 kilos. In the case of e-mountain bikes it’s 20. All of a sudden the centre of gravity of a bike becomes relevant. A heavy front means a lot a steering work. A heavy tail makes the bike sluggish. In the case of e-mountain bikes we therefore measure the wheel load distribution for all bikes. It determines the percentage of weight weighing on the front and on the rear wheel.

The height of the centre of gravity is all of a sudden also decisive. Which means in short, the lower the centre of gravity, the more responsive the bike. The worst possible case would be a centre of gravity positioned far in the front and very high. The height of the centre of gravity is determined by us by a new test procedure.

We measure the overall stiffness of the frame on a complex test stand and compare it to our results from the field test. In addition, the geometry of each bicycle is determined by a laser measuring system.

Each of these individual results of our lab tests is provided with a high or low evaluation factor (weighting factor) according to its importance. Step-by-step this makes the point scoring that you find in each of our comparative tests. You can then have a closer look on the overall rating of the bike or on the individual evaluations which are of particular interest to your field of use.
