When i stumbled over the Internet looking for a ABUS folding lock on a (according to well-known reviewers) Video showing how with a simple flip key of this lock is opened. That this method in recent ABUS locks is no longer possible may be true, because there was a similar video about the Kryptonite locks. However, reports on relevant sites on the Internet frequently about this castle, when it comes to particularly safe locks. This is a good argument MMN.
To evaluate the weight to be negative I consider stupid, because the description in the heavy weight points. Personally, I can resign myself.
In compliance with the various. Forms of security I sure my bike with this lock on the frame and the rear to a fixed object. The front wheel, and the saddle I secure with a loop cable to this castle.
The overall effect is impressive (which professional thieves certainly not impressed), but you should protect a bike if possible on a very insightful point, what deters thieves probably more of a bike with this castle.
The rubber is super, there is no risk that the frame scratched.
The only filamentous aftertaste remains in the "Bike insurance", which I personally think is a bad joke. Here is a bike insurance should be taken over the household insurance (if there is no product, many household insurance automatically insure the bike up to a certain amount with).
