Bikes on Eurostar?

seems there are two options
a:) take your bike apart and put it in a bag to take on as hand bagage - Hassle
b:) Reserve a place for your bike in the lugage train - £20 eachway! not joking!
both options look about as much fun as a poke in the eye

You forgot:
c:) htfu and deal

You either pay for the convenience or do a trifling bit of work with a wrench.
