I would estimate my solution (including the luggage strap) to weigh in at less than 500g. It folded down to about the size of a lightweight waterproof jacket and fitted in my rucksack front pocket! It also ended up around 1.2m x 0.9m which is the TGV size limit.
Basically, it's just a lightweight cover - the bike & bits are tied together and the luggage strap attached to the frame.
