I've got a bike box allan. I know there a few out there that are similar.
Things to remove- Seat post, wheels, stem (keeping handlebar on) 30-40 mins to pack
Loads of room inside box to put kit, helmet, tools, shoes etc. I plan on taking just carry on bag next year to majorca.
It has a anti crush bar in the centre so as good as it gets i think for protection
On wheels so its easy to pull along
Cost around £ 550. Cheers.
Have a chat with Dave as he has recently bought a bike box
