Also this castle is to secure my e-bike from thieves. I have it. 85cm in length, which reaches to the frame, the front wheel to the frame or the front wheel to back up the rear with a stake When you're a little careful and attentive while chaining, the lock does not leave scratches on the wheel. It's a bit unusual to use, but that should not be a negative point. I had initially problems can move a joint on the part with the locking mechanism in both directions. After oil gift and a lot of power but it was finally. Basically, a robust and seemingly good lock, the Schließmechanis differs significantly from cheaper editions. Worth a total of the whole castle of cheap locks different - I hope this makes it really safe! The included universal mounting bracket is attached with Velcro to the frame, which maintains quite well so far, has not yet slipped significantly down (by the heavy weight of the castle). I would recommend the castle and buy again.
