Brad, it is ashame that you lost your bike. We feel for you. We were living in Ft. Lauderdale, in a gated high rise building, and our bikes were locked to a bike rack, inside the garage entrance. Constant traffic, in a space that was supposedly well guarded. The thieves stole the entire bike rack with 20 plus bikes. It was probably, an inside job. One of the folks we knew, found their bike at a local pawn shop. We unfortunately never found ours. It took us a few years to replace our bikes. The worse part was we had renters insurance but, in the very fine print, they would only replace the bikes, if the bike was in a storage compartment, with a locked door or stolen out of our apartment.
Sadly, most people do not copy down the serial number or ever take a picture of the bike. This was helpful to the police, who periodically sent alerts and checked pawn shops. I wish that, like Lo Jack for cars, that a theft system was available, at a reasonable price, for bicycles or motorcycles. This would be especially useful in cities like Washington, D.C. or New York. Unfortunately, no matter how case harden a chain or pick proof a lock, if thieves are prepared or have enough time, they will get the bike.
If you replace it, and you use it to commute, get something, used, black in color, a little cosmetically altered, a minimal amount of accessories, (or stuff you can take with you) and relatively inexpensive. The other alternative is purchasing a used 16" or 20" folding bike, that you might be able to take inside, in a soft case, and store at work.
We wish you luck an hope something turns up.
