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.

"It has become calmer"

What about the safety of state-of-the-art mountain bikes?

Over the wide range of products the quality of the components has clearly improved. Seat post breakages are actually no longer an issue. Ever since the number of super lightweight components has decreased, it has become calmer.

What are the critical components of a bike?

We see problems in the handlebar and stem area and in particular where they are clamped and with the high rise. Defective brakes are not an issue for me as an expert. I do know, however, from practise that there are a few brake systems susceptible to draw air. Some lightweight cross-country pedals can brake at the axles.

What about the wheels?

A defect in this area is not directly life-threatening. Thanks to disc brakes there are no more valves shearing off. In addition, the new hookless rims function well with the low pressure mountain bike tyres. Sharp rim flanges of carbon rims can, however, be dangerous, if they make the tyre suddenly burst. Carbon rims should anyway be checked regularly in case of tough use.

Which type of bicycle causes most headaches?

Dirt bikes must apparently be low in price and are, as a matter of fact, subject to heavy loads. A broken fork is nothing special. In the case of pedelecs inadequate designs are found every here and there.

Be careful! These are the critical components of a bike

1 Handlebars/Stem

Every crunching noise can mean severe injuries. We advise against extreme lightweight and refer to the results of our breaking test. (www.bike-magazin.de)

2 Frame/Fork

BIKE readers report on lots of damaged frames which do, however, not result in a fall and are handled on a goodwill basis. According to the experts, fork breakage is rather frequent in the case of cheap dirt bikes.

3 Wheels

Wheel failure resulting in a fall is extremely seldom. Be careful in the case of carbon rims: Sharp-edged rim flanges can slit the tyre carcass which can have severe consequences in the front area.

4 Saddle and crank

Occasionally we get notice of super lightweight seat posts which fail. Sometimes we are informed by readers about broken pedal axles or threads thorn off the crank.
