Chain-style bike locks are nice because they're flexible, although they're kinda limp – like a piece of boiled spaghetti. The Abus Goose Lock 6206K is different, in that it's bendy but it holds its shape – more like a giant pipe cleaner.
At the heart of the Goose Lock is a 6-mm hardened steel chain. Woven throughout the length of that chain are two metal spiral strings. These are what allow the Goose to be easily shaped by hand, and to stay in that shape as long as required.
The chain and springs are covered in a layer of foam rubber to minimize rattling. An exterior woven-plastic fabric skin protects both the rubber and the bike's paint. A key locking mechanism is built into the two interlocking ends of the Goose.
So, what's the point? Well, Abus states that the lock can quickly and easily just be wrapped around the bike's frame while in transit, staying put and not making any noise.
Additionally, securing it around immovable objects such as sign posts may be easier than is the case with a droopy conventional chain lock. Prospective buyers should note, though, the Goose has a rather mediocre Abus security level rating of 7 out of 15. It's intended mostly for use in low-theft-risk settings, or for quick lockups when going in and out of stores, etc.
The Goose Lock 6206K comes in two lengths – 110 and 85 cm (43.3 and 33.5 in) – the longer of which is claimed to tip the scales at 1,120 grams (2.5 lb). It's available in color choices of black, green, blue or pink, at a suggested retail price of US$89.99 for the long one or $79.99 for the shorty.
