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.

Where is the best place to store rechargeable batteries?

Reader’s question

Related to this subject you presented a special-purpose cabinet on page 57 of issue 1/13. Well, what I want to know is this: Are such cabinets on sale for domestic use? If so, please name a manufacturer. If not, I have a metal cabinet in my garage. Is it necessary to provide it with an additional fire-resisting lining? Are there any regulations as to ventilation?

Li-ion batteries of state-of-the-art pedelecs have a high energy density and therefore bear a certain risk potential of spontaneous ignition. Therefore you should make it a rule to handle rechargeable batteries with care and to only use original chargers. Charge the battery only during the day and under supervision in well-aerated rooms at about 15 to 20°C and on an incombustible ground, e.g. ceramics or glass. This will avoid the highest risks. Special battery charging cabinets, like the battery safe from Thun used by us, are inspite of the costs recommended for manufacturers, dealers, hotels and other facilities accommodating pedelecs. Pedelec owners can purchase a special bag, i.e. the "battery bag" from the same manufacturer ( to be on the safe side. For private use there are no specific regulations. You can also use your available metal cabinet. Place the batteries on tiles or the like and remove flammable material from the cabinet, in particular aerosol cans, chain oil or rags. Whether or not a garage is a good place to store the battery depends on how cold it is in winter and on how hot it is in summer.
