In reply to Tim Davies:
Paisley Freight is pretty good; their website caters for all kinds of weird objects.
Pack the bike well; there is no courier whose monkeys will not throw the package or drop it off the back of a truck. Many of them act as agents for TNT who damaged a bike that I sold on Ebay by driving a sharp object like a fork truck tine through the carton. Annoyingly, the buyer's wife signed for it "in good condition" causing me one hell of a headache so be sure to warn your consignee not to be harassed by the driver but to inspect the package and sign for it as "damaged" if in any doubt, so as to have a comeback against the courier.
