Code locks are well easy to open. Just pull both sides of the chain tight, spin the codes round and push to the left. They will slot in the grooves and lock opens. Literally takes seconds.
Hmm I didn't know that. Bolt cutters sound fun though.
I did some investigating on google street view and it's been there since at least 2014, no sign of it in 2012. Although it still had both wheels attached to the frame at that point. Both wheels are off and locked up with it at the moment.
Just looks like a chain with a plastic outer, could be a very thick cable though. It had a code lock.
You’d think the code would eventually come back to someone if they set it and forgot temporarily.
