Ways not to lock your bike

If you lock it like fixie boy has, you get the protection of two ends rods of the U part of the stand. If you locked to the U directly, Mr Thief just needs to put one cut in it and swivel one side to release the lock, in the situation pictured it would require two cuts.

Hmm... I'm very sceptical about that claim.

I suspect if you rotated the frame around the vertical axis 90 degrees, so it's parallel to the arm, you could slide it off without too much trouble.
