How does one review a bike lock? A large factor to consider in any security equipment is the reassurance it gives.
I regularly lock my bike in central London, and I can say that from the specs, the hefty feel of the thing and its high security rating, the Abus is probably is better than 80% of locks I see used to secure other bikes.
The main rival to this lock is the Kryptonite 'New York', and if you read reviews, there is little to choose between the two in terms of strength. I was tempted by the 'New York', having always had Kryptonite locks in the past and never having lost any bikes while using them.
However, I chose the Abus because of these factors-
-Comes with two keys, one with an in-built light. Also a unique key-card meaning replacement keys can be ordered. Being a European (rather than American) company, the chances of decent customer support seem higher.
-The easy-fit bracket works really well and is far superior to the poor quality brackets supplied by Kryptonite.
-The general dimensions of the Abus are designed for European/UK use(rather than American).
-Reviews of the Kryptonite lock carry stories of the keys breaking in the mechanism. The Abus feels satisfyingly solid when inserting the key.
Overall, I am satisfied with the Abus lock and would recommend it to others. Downsides? Perhaps the weight, but this is the price of security and I actually find it reassuring. Also worth noting, I had thought the dimension of 30cm referred to the entire lock whereas it actually seems to mean the length of the 'U' section. This makes it quite a long lock, potentially giving extra leverage room to thieves.
