I was hit a few years ago on a really cheap Viking Fixie (IIRC £195). When the driver discovered, 'it was a really expensive bike' they baulked at it and went through their insurance that did take a few more weeks but I think the insurance company were happy to 'snap my hand off' and quickly settle, even though I inflated it slightly. Another time I was hit on a more expensive bike however, and it did take a while. I hope you are sorted soon
