Hi Talya, I think that during next days I will call some bike rental company for ask to they. They'll think I'm crazy. If I really cannot find another solution I'll take mine, with me on the plane. Thank you for your reply!!!
I think that the shipping (as for baggage on the plane) is less expensive that buy another one there. Ryanair (or similar) to ship sports equipment ask 50€, but a new bike is worth at least 300€. I dont know what to do.
I was just thinking about all the hassle, taking it to the airport, checking it in, retrieving it on arrival, transporting it to where ever you are going to start, possible theft, the whole works. 300 lbs does seem like a lot of money, but you can always sell it before your return.
