No thieve in the world can break this lock!
Sorry, unfortunately, that is not true. And we are honest with you as we want you to correctly estimate the risk for your lovely bike to take the best measures. Of course, other lock producers promise unbreakable protection but this is simply not possible for any bicycle lock - no matter how big (just think of a thief with an angle grinder and enough time to spare).
However, what we offer to you is the highest possible security for a lock that can be conveniently carried with your bike. To make a long story short: There is no better way to keep your bike in your hands than with this security folding lock.
