U-lock stuck on a bike Some time ago, I stuck a U-lock on my bicycle for safe keeping, on the top tube below the seat. It's annoying when riding, and I'd like a way to remove it. I've lost the key some time ago, or I would have removed it that way. Preserving the lock is optional. What would you suggest?
I figured out a way to do it which was actually fairly easy. This only worked because it was in my garage, trying to steal someone's bike like this would be crazy...

I took a hammer, and pounded on the bar. The first thing that happened was the plastic broke away. I kept pounding on it, until the lock just fell apart. It took about a minute...

Note to self, don't buy a cheap lock next time...
