Neat idea but I already have a bag underneath my saddle. My frame pump is mounted on the side of my seat tube and is out of the way enough to not be a bother.

Clever, but I see a couple of issues. One, when patching or replacing a flat, pumping a tire that is off the bike looks like it may be difficult. In the case of a rear wheel off, the bike would have to rest on the rear dropout and may damage the rear derailieur. And if it is the front wheel that is off, then the bottom of the front dropout would be scraped. And two, the bike must be steadied while pumping. And if there were a kickstand, would the pumping put too much pressure on it?

Yes, my nearly decade old Dahon Mariner folding bike came with a seatpost pump, an option still today on Tern bikes from their Biologic accessory line: BioLogic PostPump 2.0 Seatpost | Premium Bike Gear
