Easiest thing to do is to go to Competitivecyclist.com and fully detail your bike, email yourself your configuration with pricing.
Politely talk with the adjuster and tell them that you ache and hurt but want it to pass, and if they replace your bike so you can be done with it, you'll be on your way. Ask NOW for an equivalent rental bike which probably will be about $60/day. "Oh, are you able to go out cycling?" "I sure hope so, and am hoping all the stiffness goes away. Do you want to pay for a rental bike for a few weeks, pay for my bike then and find out or replace my bike now?"
Be sure that you don't need medical treatment. Ask them to Pay for your bike NOW and give you $500 for the grief. They'll ask you to sign a 'Release for any further claim of liability'. If they want to subtract 10% for depreciation, fine. You should be able to get that from a dealer selling you a new bike.
Best,
Jeff
