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.
The Scott brochure displays the 2016 model Genius 930 (M) with a weight of 12.7 kg without pedals. I bought the XL-version of this bike and found out that it weighs one kilogram more than indicated in the brochure. Scott’s explanation that the tyres and the frame may add up to a difference in weight of 600 grams is not satisfying to me. Don’t I have the right to a bike at a weight of 12.7 kg plus/minus a little tolerance?
The opinion of graduate engineer Dirk Zedler, two-wheel expert:
"During production weight tolerances occur, in particular in the case of carbon frames, tyres or saddles. Therefore, a deviation of some 100 grams cannot be avoided on a bike. In addition, manufacturers often indicate the favourable value of an M-sized frame or smaller. A deviation of one kilogram is in our opinion, however, too much. The question whether this represents a material defect justifying a return should be decided by a court. The fact that the specifications of some manufacturers were much more realistic in the recent past, leads us to assume that in these cases the buyers were successful."
