The bicycle lock is as far as I can tell, solid built and can be good and smooth opening and closing. It is handy that the lock is locked with a small sliding cover that protects the castle from moisture and rain. At one key is a handy, blue light that can be switched on a touch away. Certainly sinnig for those traveling a lot in the dark. For my 08/15 Rad certainly ne good purchase decision. Whether I would thus secure a € 2,000 bike I do not know. Since there is certainly more stable variants. But for my purposes quite ne good choice this castle ...
