Your parents need to present a claim against his Insurance for damage to the bike or for any injuries you may have sustained. As a minor you can not make your own claim.
now i'm not American but isn't a crosswalk for pedestrians only to cross a road and if you wish to cross as a cyclist you must dismount and walk with your cycle. why I ask is if you did ride your cycle over you will be on very dodgy ground to sue him as you would be illegally doing something.
