Another thought, if you aren't in a hurry, then consider buying a decent 2nd hand in the UK and bring it over. We have bought two bikes over so far. The airlines charge between £25 (easyjet) and £50. You need to get a box from a bike shop to pack it, the airlines have details on their website on how.
You can pick up a really decent 2nd hand or a well built entry level mountain bike and bring it over, for probably less than buying here.
It's also very entertaining watching the customs guy running after you at Dalaman as he thinks you're bringing in a new tv in the box. The disappointment on his face when he realises its only a bike as he thought he was going to get his hands on a new tele!
