Some TGV trains have special storage spaces for fully assembled bicycles. Expect to pay around £10. Bicycle spaces must be reserved when you book your tickets.
Or you can take your bicycle in a bike bag (which must be no bigger than 120x90cm) free of charge.
Bicycle spaces need to be booked at the same time as you book your seat. To make your booking, phone the Rail Europe call centre
or visit our London Travel Centre
as bike spaces can’t be booked online.
