I am posting this for my 23 yr old son (I'm a librarian...its what I do!):
He's joining friends in Barcelona, Spain who are bicycling from there to Nantes, France. He will go only partway as he needs to return home to work earlier. He's hoping to rent a bike in Barcelona, leave a little luggage (from previous traveling w/o bike) and return with bike on trains from wherever he ends up at the end of the time he has.
Is this reasonable? Certainly renting or buying a touring bike doesn't seem to be a problem. We've identified likely outfitters that do that. But on other forums I've read that travelling with a bike on trains is more doable in theory than in practice. On the other hand, selling a used bike in a strange town in a very short period of time seems awkward as well.
Any advice welcome. Thank you!
