For the benefit of everyone, I'll try to explain, since I've installed it. Please refer to the picture below. It's quite self-explanatory. Sorry for the pic quality...a bit dark but you'll get the picture (no pun intended).


Yes sysh, the screws are 'hidden' in its locked position (refer to pic above).

I'm not saying it's impossible for a determined thief to break/saw/detach it but it makes it quite difficult to do so. Besides, there's nothing that's 100% foolproof. You are buying added peace of mind and time to stall the thief. IMO, this Aorto Lock is as good as they come for pedal locks. No messy wires cutting, no obstruction to pedals, no voiding warranty. I'm satisfied with it.
