The castle is nice and long and not as stiff as a tank lock, so I chain my bike sometimes to a lamppost kann.Leicht the castle is not, but I if I do not need it in my bicycle box on the Gepäträger put the lock interferes me not. The lock deters thieves from its solid äußerses and has a high security level. In the handling, it is easy to unlock the key to close into each other. I got my bike until now always there found again where I have connected it. And if a bicycle is stolen or not is also somehow also random and depends on several points from such as the time of day or of the area in which I am connected habe.Ich my bike with the lock very satisfied and would definitely still Buy once and it empfhle on.
