With Puky I have some problems. They advertise German engineering feat, but I as an engineer and Zweiradmechaniker find anywhere mi detailed technical defects! Was it almost impossible for the front reflector to exchange (supplied defective), I was pleasantly surprised by the attachment of the support wheels. Here someone has really thought about it. Everything fits and is clean snapped and bombproof. This can not be said of this pennant. It has no equivalent on the wheel where it locks or locked. It is simply screwed. The bicycle is with us under the balcony on the terrace and is exposed to the wind (not rain). And if only this manages to loosen the tightened pennant over 3 months so that it slowly but surely in the travels one direction or another. So something happens, even when driving. You can not be traveling with a Puky simply without tools. Mir is a mystery how Puky may occur so good reviews. Going into detail then you will always find flaws. I have the management of Puky advised their engineers their own children's bicycles to give to their children. Here, the defects should be visible and are already shut out of self-interest in daily use. The answer to my list of deficiencies with concrete improvement measures failed to materialize. Too Bad. I will never buy anything again from Puky. This Fehlkauf taught me a lesson!
