Motobecane Elite FS Hybrid Bike (with Lockout Suspension Forks)

What happened

I locked my bike in front of my building (literally in front of the window where the doorman looks out of) on Wednesday (May 30th) around 6pm. I locked the bike around a street sign that was secure (as in in the ground solidly) around the spoke and the frame. The wheel is quick-release, so I always lock around the frame and the wheel. I arrived just now (Friday, June 1st around 8:15pm) to find the lock (an OnGuard hefty ULock with a flat key), completely in tact and locked, and no signs of the bike. Any help you can offer would be much appreciated. It's a pretty distinctive, somewhat girly bike, with a lower seat and ride (because I'm shorter). So, if you see a dude riding it, it would look...very strange. Thanks!
