Posting a bike to yourself overseas

Hey folks am off on a round the world trip in december-predominantly snowboarding but am coming back via thailand and plan on spending a couple of months there kicking back and exploring.Ive done a fair bit of cycling in thailand but the bikes are mostly run down shitters A decent bike is quite exxy for a day hire even in Thailand.Any idea of the cost involved or to say pre packagein a bike box and have a friend send it to you over there?
