My motorized bicycle was cable locked to a concrete pillar in the secured parking garage at the apartment my girlfriend lived at. You had to live there in order to have access. It was stolen on my birthday last year by a tennant who was moving out the same day. Loaded it into the u-haul behind the building as he was leaving with the last of his crap. My new motorized bicycle is almost complete and I'm not taking any chances, I'm going to use a Kryptonite cable AND a U-Lock.
