This is a tough one to ever close. other than keeping an eye on craigslist, or going to local bike dealers to see if they have gotten them for trade-ins, theres not too much more the community can do. Even if a thief did steal them, without makes and models, or even pics, its tough to stop every child on the road with bikes matching those descriptions.

Have you reported this to the police, and claimed it on your homeowner's insurance?
It will always be very tough to close this because you may never see the bikes again. I recommend keeping bikes out of public view, and locked up to avoid having them stolen. But beyond that, you should consider closing this in a whileif you dont get the bikes back.
Sorry that this happened. Good luck!

unfortunately, my buddy doesn't have any pictures, or i would have posted them. the police say most bike thefts are "ride&ditch" situations, and that the bikes would probably be dumped after their initial use. the bikes were out of view (in a garage), and their monetary value isn't why we want to get them back, so claiming them on insurance is silly. i've done a few drives through mid-town and across broadway hoping that one of them would be propped up on a house, or thrown in a bush, with no luck. thanks for keeping an eye out! all we can do now is wait and hope : )

Just this... if you have a digital camera it is cheap and easier to take pictures of bikes and the like... a "this bike was stolen: please return it" with a picture might deny the thief the pleasure of public rides or maybe just prompt someone to encourage the return. Especially if the bike was stolen and then given as a "gift".

IT IS SO FRUSTRATING TO HAVE BIKES TAKEN . THEY ARE USUALLY GIFTS OR A WAY TO GET TO WORK, I CAN ONLY BLAME THE LOW LIFE THAT LIVES IN THE CITY AND DOES NOT TEACH THEIR KIDS THAT STEALING IS WRONG.

Sadly, even after driving around looking for them, they were never recovered
