I'd like to see how well a thief gets away with either a large set of bolt cutters on a bike, or a cordless cip-saw... Maybe if it's in a desolate area, with no eyes looking, for a 10 minute period at least.
Huge bolt cutters, or a cip saw being used on a bike will quickly draw attention. And, that's the one thing a bike thief doesn't want. And, the ride away, rolling down the street with giant bolt cutters. Would be stopped by most cops rather quickly (Possession of burglary tools).
So, he'll just take the bike next to it with a flimsy cable lock, or not locked at all.
And, I wonder how many cip-saw blades one would go through cutting though AL rims. My experience shows cip-saw blades gummed up after about 10 seconds of being used on AL.
