Here's an idea I don't have the time, experience, or wherewithal to follow up on. My toddler today got his first suitcase and it has the plunger handle that pops up so you can roll it through the airport. He yanked it up and pushed it down and that was the same thing I showed him to do with the bike pump, so he looked for the hose, and he didn't find it. Why not do that with a folding bike case?
