Are you looking for the strength of a U-Lock and the versatility of a cable lock? The Bonelock is yet another innovative Bicycle Security Solution exclusively from Bike-Guard that is once again redefining bicycle locks. Bonelocks can open up to a maximum circumference of 41", and can be formed to the shape you need for difficult locking situations, and folds up into a size that is far more compact and convenient than a U-Lock. Thieves don't know what to make of this lock, and it is resistant to many of the methods that are commonly used to try to break U-Locks.
Hmmm...Stronger, Lighter, More convenient...We rest our case!
