Take your bike on the TGV Lyria, no booking necessary. A single condition: the wheels must be removed and stored with the bike in a bike bag.

Never travel without your bike? Good news: with the wheels off and stored in a bike bag (maximum dimension 120 x 90 cm), your two-wheeler can travel with you free of charge and with no booking required, in the TGV Lyria luggage storage areas.
However, it remains your full responsibility on board the train.

For info: you must take the bike on and off the train personally. In the interest of everyone, travel outside peak times.
