I travelled back from Valence with mine yesterday. As long as it's bagged no-one mentions it. There is a lot of luggage storage space on a TGV so it's usually easy to find a space you can fit a bagged bike in. I couldn't yesterday so stood it in front of a rack, slightly blocking the aisle. I thought I might get asked to move it but the train manager just shrugged in a very Gallic manner when I asked if it was in the way.
