When I travel, I ride to and from the airports whenever possible, one of the headaches that this produces is the problem of packing the bike for flight. There are boxes available, either hard case or just an old box from a bike shop, but it's not the sort of thing I want to ride with for 20km+ on the way to Tullamarine. There are bags available too, but from what I've seen so far, they lack any form of protection for the bike, and if you've seen the way the freight is handled you'll know it's needed. I tend to just buy a cardboard box at the airport, but there is always the chance they will be out when I get there, especially around the date of a bike event. This Bike Wrap from Jooks seems like a plausible solution.
