The anti-theft protection for the wheels and saddle is nothing new. Until now, axles were used that could only be opened with specific keys. And this is where Abus comes in with "Nutfix" and presents its own solution. The highlight is the special way it works. The nut for tightening the tensioner is equipped with a mechanism that only releases the screw underneath when the wheel is on its side. Otherwise, no access is possible. Abus calls this gravitational technology and what sounds like high tech can be operated quite simply with an 8 mm open-end wrench.

Let there be sight

The "Optic" helmet study is somewhat futuristic. This was devised by the British industrial design company DCA. A camera on the back of the helmet in combination with a visor with an image overlay function provides an all-round view. This probably has little use for trail riding. But on a city bike, a constant view to the rear could ensure greater safety. Motorized road users are leading the way: They don't do without a rear-view mirror. The modern helmet - as it has been presented as a concept so far - also has a proximity sensor and thus provides the rider with information about approaching road users. There is also a camera at the front, which can be used to document journeys. The "Optic" helmet has already won the Red dot Design Award 2016, but it is not yet clear when and where the augmented reality helmet will be available to buy.
