It's a simple chain lock. It feels very sturdy and robust and it's easy to lock and unlock. It is made from inter-linked bars, rather than a chain of links. The way to fold is to unlock from the case then push it down to unfold it and take it put from the top.

The lock system is nice, and you will like the feature alot. It is easy to transport on the bike using the included carrier. This requires a lot of space and one you mount in the bike the frame will be on the way to do it easily. It is really heavy and bulky and it is kind of difficult to get the lock back into the holder after folding it up.
