All about bicycles, electric-assisted bikes, 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., 2022/07/22

Warranty coverage also for wearing parts on e-bikes?

There is no bicycle the chain and cassette of which wear down as fast as on e-bikes. Sometimes, the drive already fails after 500 kilometres. A case of warranty? Expert Dirk Zedler clears things up. (...)

Is there at all such a thing as warranty for wearing parts?
Dirk Zedler: Liability for material defects, meanwhile the correct term, is a delicate subject in the case of wearing parts. In principle, wearing parts are not excluded from the liability for material defects. Such products must also be within a reasonably expected service life for this category.

This leaves room for interpretation. What exactly would be a reasonably assumed service life for an E-MTB drive?
Dirk Zedler: That’s actually often a point of contention. Especially information on the correct care, maintenance and replacement intervals of a product should be included in good operating instructions. If in doubt, consult an expert. I am of the opinion: A bicycle chain on a high-quality e-bike for, let’s say, 4000 euros should last at least 1000 kilometres. Components such as the cassette should last longer. Currently, this is hardly realistic because the components still used on e-bikes are not up to the high drive force. This is actually unacceptable for the consumers.

Why are there still hardly any lawsuits against dealers or manufacturers?
Dirk Zedler: The amount in dispute is simply too low for wearing parts. With 250 euros for a new chain and cassette, you will hardly find a lawyer who will go to court over it. Besides, the dealers cushion probably a lot. The situation is different, however, with major damage, where even the dealers see themselves unable to cope with. For example, in case of damage to the electronics. Due to the larger amount in dispute, the reverse transaction of an entire purchase contract is also often at stake here, and lawsuits are much more frequent.
