With security is not a matter of making it impossible, but making it too hard to be worth trying. This lock meets that standard. So much that the biggest concern now is making sure you don't lock yourself out! I ordered a couple extra keys just in case, not knowing they (of course) anticipated this and include four already.
The security features are comprehensive and legion, but they didn't stop there and added 'quality of life' features like a captive center pin. No problems with it dropping on the ground when you unlock. And in an apparent 'go to 11' move the lock cover is itself intimidating. I'm surprised they didn't add a secondary lock on the lock cover, just because, you know, because :) :)
So add a serious chain on the wheels, like an ABUS square chain lock and Granit lock, and you're as secure as you could hope for.
