Bikes on Eurostar?

All non-folding bikes or those over 85cm long will need to travel with our registered luggage service, Eurodespatch, in either London, Paris, Lille or Brussels. They’ll also need to be dismantled and placed in a bike box or bike bag. We can provide a box for you, which is included in the service price.

Is that news to you, as it is to me?!
