ABUS CityChain 1010 chain lock - hardened steel bicycle lock - security level 12

I already own a Kryptonite Evolution Series 4 Standard Lock with EZMount Bracket , but the standard advice is to use two different locks (apparently thieves tend to carry tools for just one specific type of lock). The Abus chain lock is pretty tough and is (obviously) more flexible than a D-lock, so is useful by itself when the item I want to attach the bike to is too big for the D-lock. It's also easy to carry on a bike - just double-wrap the chain around the seat post. I was hoping it might lock itself automatically when inserting the two chain lock pieces together, but in fact you need the key both for unlocking and locking - it's not a big deal anyway. Very pleased with the quality of the lock and would buy one again.

The lock is easy to use and reasonably flexible for a chain. The chain is encased m a flexible cloth sheath so doesn’t scratch/chip any surface it is touching.

My bike is still outside my house, so I can't give it a higher recommendation.

Brought this back in Nov 2012 worked a treat until the key broke in the lock now I've got to cut the chain with a grinder so be careful when unlocking this chain as the key may brake inside the lock apart from that I would recommend this

Definitely feel like my £650 bike is totally safe, any time of day, even overnight. I wear this around my (pretty slim) waist, which is super convenient. That's why I chose the 85cm. This is borderline a motorbike chain; super heavy - probably half the weight of my modern racing bike if not more.

Heavy but strong lock. Gold standard means it qualifies for bike insurance for more expensive bikes.

Good quality lock, does the business

This lock worked OK for 9 months and then for some reason the key would not operate the lock. I tried everything to get the key to work but to no avail. Luckily I was in the process of locking the bikes up so did not have to get someone in to open the assembly or cut the chain!!!! - I have only just got around to reporting this. I'm not happy that such an expensive lock can fail and will tell ABUS

Muy bien, funciona a la perfección y el precio no se compara con el de otros vendedores.

Robuste et efficace

自転車を玄関先に置く為に購入しました。 頑丈なので諦めて帰りそうです。少々重いですが・・・

This is a great bike lock. Don’t leave home without it.

Känns stabilt😁
