All about bicycles, electric-assisted bikes, technology and safety in the press

The most common safety risks that we come across in our daily work around bicycle safety, technology and operating instructions are also published by us in articles in the leading German special-interest magazines TOUR (Europe's road bike magazine no. 1), BIKE (Europe's mountain bike magazine no. 1), MYBIKE and EMTB in order to make this information, which is important for the industry, available to a wider public.

For many years now, the Eurobike Show Daily, trade fair magazine of the annual Eurobike Show, has also given us the opportunity to publish our view of major developments in the cycle industry in full-page articles.

We also speak regularly in independent expert presentations about all areas of bicycle technology and the bicycle market. In addition, we are quoted by further special-interest magazines of the industry and the trade as well as increasingly by radio and television in their media reports, which shows us that we are spot on with our advice. The section "News" informs you about the latest news from our specialist areas. The reports and publications of this section are listed chronologically or according to areas of interest.

Recall: E-Thirteen cranks on Shimano motor

Bicycle manufacturer Stevens recalls some 2021 models of the E-Inception series on which E-Thirteen cranks and a Shimano EP8-drive is assembled. Several models showed cracks in the drive shaft of the motor. But other manufacturers with the combination E-Thirteen/Shimano are also concerned. Stevens is, however, the only one to give out an official warning to their customers. One reader reports indignantly that the crank on his Liteville had fallen off when riding down the stairs. We asked bicycle expert Dirk Zedler what worried customers can do.

Reply by Dirk Zedler, bicycle expert:
“For months, posts with pictures that leave no questions unanswered have been circulating on the net. Regardless of the e-MTB manufacturer, the combination of E-Thirteen cranks with Shimano EP8 motors involves risks. Sometimes the cranks come loose, sometimes the shafts break in sharp edges. The result is the same: If the crank including pedal falls off, there is a risk of accident with unforeseeable consequences. Stevens’ measure to protect the riders is consistent and right. The fact that other manufacturers concerned remain quiet reflects badly on them. Putting the health of customers deliberately at risk is irresponsible in my view. In any case, riders should ask the manufacturer via the dealer what measures are being considered. It would not be the first time that manufacturers rethink under the pressure of requests.”
