The strongest lock in the world, without a doubt. Thieves will move on to easier targets when they see this monster!! Very well made with good coating protection to avoid bike damage. Obviously the weight is unavoidable if you want the strongest lock in the world, but there are two relatively minor problems that could be easily be resolved. The lock is a bit awkward to use. Not a very positive key insertion, so a bit fiddly. And for ebikes with larger frames, the lock is just a bit too small. Obviously an increase in size means an increase in weight, but it would be worth it to to suit ebikes which need more protection due to their higher cost. But, still the best lock for peace of mind.
