Airline Baggage Regulation / Flying with Bikes

Anyone have any experience of bikes on ryanair?

Their website seems to be saying if you pay the fee it can weight 20 kilo on top of your normal baggage. Is that true? I don't put it past ryanair to change their conditions at a moments notice.

I took my bike from Stansted to Carcassonne and back with Ryanair last year, having pre-booked and paid for it when I bought the tickets. (Flights: £2. Booking fee: £10. Bike: £60.) No problems whatsoever.
