C'est comme pour toutes les compagnies d'ailleurs c'est écrit sur leur site :
Travelling with a bicycle
You can check in a bicycle as a piece of check in baggage provided it fulfils the following requirements:
A non-motorised touring or racing, single-seat bicycle
Handlebars that are either fixed, tightened sideways, tightened parallel to the frame or enclosed in plastic foam or similar material
Pedals that have been either removed, fixed inwards or enclosed in plastic foam and similar material
Deflated tyres
Packed in a strong and protective hard case or recognised bicycle box
Sinon c'est quoi la question ?
