If my headline worked, you’re now mentally humming the Transformers theme song, pretending to mimic that robotic voice and hopelessly trying to remember more than the main verse.
Happy Bike, in the meantime, has produced a real transformer in the form of a folding bike that can actually be ridden.  Since their website is heavy on the Engrish and light on useful information, I couldn’t find specs to see if you could actually carry this on and put it in the overhead…but that would be cool.  Then you could unpack it after security and ride around the airport.
The only downside is that when it’s not a bike, it transforms into a boring suitcase.  Kind of like Frenzy (robot, tape), when it wasn’t in it’s action state, it was a lame cassette tape that just sat there.
