Sell it and buying a used bike in the US is the best option. For the money you will get for your bike in India you can buy a much better used model out there. Just saying.

Check with the airline that you're flying on...I know Etihad used to be either $200 or $300 for putting something in the cargo hold, from a dog in its crate to a bike. Worth checking out with your airline if you're serious about bringing it - and probably cheaper doing it that way than shipping it.
