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 05/2001

Caution, pitfall

1,000 German Marks fort his heap of scrap? When buying a bike second-hand, you run the risk of a write-off. Nevertheless, second-hand is in fashion as the first owner has to take the biggest depreciation. BIKE reveals everything about risks, buying strategy and real big hits.

Keep your eyes open when buying second-hand

BIKE-expert, graduate engineer Dirk Zedler, gives some advice on guarantee, defects and the first check-up when buying a bike
BIKE: What’s the guarantee-situation like?
DIRK ZEDLER: This is a rather unpleasant topic for the buyer. The voluntary manufactuer’s guarantee only applies to the first owner with all brands I know. No matter how old the bike is. 

And if there is a severe defect?
If the manufacturer is responsible for the defect, e.g. when assembling a wrong stem-handlebar-combination, legal product liability will apply of course. But also in this case, there are some borderline-cases: When the first owner has converted the bike or – custom made – assembled it himself. In this case you have to be careful. At best, the buyer makes sure by checking original invoice, repair receipts, guarantee cards and owner’s manual whether the bike is in its original condition. The BIKE-Markt magazine of the respective bike’s year of construction is a must anyway. 

But most bikes have been converted, haven’t they?
In this case, I recommend having it checked at a specialized dealer’s who knows the respective model. The worst accidents happen in the stem-handlebar-area. I personally would always renew this combination when it is older than two years of age. This is not so expensive, but my life depends on it.

Which other parts should the buyer pay attention to?
From my experience as a bike expert I know that, beside stem and handlebar, most defects occur with wheels and suspension forks.

How can the buyer protect himself against this?
Although it is nerve-racking – deflate the tires and measure the rims’ wall thickness with a vernier caliper. If it is one millimeter or less, there is the danger of rim bursts. Check, if the suspension fork works. Many models are done after two years without having been used heavily.
