LOL Just kidding the portaband would be the best,no sparks like the grinder and no slag like the torch. I'm a Sheetmetal worker and have lots of experience with all types of metal,if you wanna do it on the cheap hacksaw.
You'll need a tungsten carbide hacksaw blade if you go the hacksaw route...the hardened steel of a U-Lock requires it. Milwaukee sells a good one through amazon.com if you can't find one locally. You still have to eat your wheaties, though, as getting through the U-Lock still takes ~30 minutes of sawing.
Got an old abandoned Schwinn breeze this way. Overhauled it, built up a new wheelset for it, and now it's my girlfriend's commuter.
