With such shitty resolution there really isn't much you can do with it unfortunately. This ios the best I can get out of it. The driver appears to be Indian or maybe black.
I'd take the pictures and post them on your local Craigslist and spam post them in different categories. Also, try local Facebook pages and what not. You may catch a lead, or at least put enough heat on the kids that they'll ditch it someplace and it will be found.
Good luck on recovering the bike.
