Customer Reviews

it's not bad for medium to low bike crime areas
Kryptonite STD U Lock seems to be a decent lock but it still can be "infiltrated" by a knowledgeable master thief/master lock picker in probably under 1 hour time. I'm not too worried since it is sizable, hefty looking and very heavy (2 lbs), so it looks bigger than what I saw on other bikes in the bike rack and my bike is only valued at $285.

The keys are very flimsy and forged with cheap metal so I won't be surprised in 2 months that they snap or are damaged. The Lock holder (cheap plastic) didn't work on my bike as the Lock is too big to fit anywhere so I just snug it into my rear rack. Comes with a cable (be warned, it can be cut quite easily so don't use it as a "main attachment" to a pole, bike rack, etc, just use it to secure your rear or front tires with the U Lock attached to a pole, bike rack.).

In all, it's not bad for medium to low bike crime areas but don't use it for expensive bikes, big cities, dangerous zones or in dark desolate areas where a thief can use high powered tools or torches.

Good product
Good product. Only the mount could inspire a bit more confidence, but seems to work.

Serves its purpose
This lock works well. It is a little heavy, and I could not attach it to my bike anywhere, so I carry it in my pack. The cable makes it much easier to lock my bike to various racks, and makes it so I can lock up my friends bike at the same time. I would buy this again.
