Yeah, I wrote a thing up here. I actually heard it's not even two u-locks you want but a u-lock and a...chain or something? There's some kinda master-class crap on Youtube or something but basically the were some people out here probably ten years ago trying to figure out what would keep a bike from getting stolen. And they found that mixing a u-lock and a __ (I am going to assume a thick ass chain yet again - with a solid ass lock) was the best combo. But tbh nothing stops a monster =/!
