I hope you saved your receipt for the bike. Even if you didn't, take the busted bike to your LBS and get them to write you up a quote for a replacement bike. Make sure they include any aftermarket parts. Actually, you should get quotes for all of the damaged bikes. Take the quote with a copy of the police report to the insurance company of the person who was at fault in the accident and make a claim. If you were an innocent bystander/passenger, you should not have to pay a dime to get your bike repaired or replaced.
