This bike lock is just plain awesome. It is nice and compact, but at the same time very durable. While it may be a bit more than your average lock its worth it. How many other locks are so strong, while also being the size of a hockey puck. None. Go buy this now you will not regret it.

Small compact design, light weight and mounting bracket may be mounted on seat stem and as a bonus it is extreamly difficult to cut with bolt cutters. It would likely still take a great deal of time to cut even with a reciprocating saw.
