They should add this option to electrical hubs that power ebikes.......

I could use 4 of these for my car - one for each wheel. I've yet to see the self inflating tires promised by Goodyear http://newatlas.com/goodyear-air-maintenance-technology-tires/24229/

$336 for a bike pump ! ! ! This is complicated therefore problematic therefore a burden & a bother if you get stranded because of it. Doubly so, you put this on your fork & hooked up this crazy thing, omg. I have a tiny little shock pump that can pump up over 200 psi and will fill any tire, mind you it takes practically forever to do it, but it's smaller than this. Here's the thing: the compressor does you no good if you don't have the patch nor the tire tools. I put all my gear into my saddle pack and it goes with me everywhere. I dunno, I practically never get a flat, but if I do at least I have the right stuff & it's going to work. I even pack a couple spoke wrenches! Omg this compressor is not a good idea.

This might be attractive with a pump mechanically driven from the cranks or front hub. It could also be wheel mounted as needed to finish inflation. One could start riding after spinning the wheel by hand, and get most of the pressure by riding, with no tank at all.

charge pressure while braking,

silly -
there are about 15 sources of flats where the air just goes whoosh and no amount of pumping will stay ahead of the leak
so lets say you have the spare tube and it;s installed, now what do you do, ride it flat til enough air goes in?
flat front tire is dangerous even for 25 feet of riding
back flat tire can roll off and get caught in the frame
riding flat can easily cut the new tube on the wheel rims between road and rim
just - who would buy something like this, except someone who does not ride at all?
then they will just be disgusted with how useless it really is..

When you need to inflate the tyre, could you not disconnect from the pump, and using the same lead, plug into the tyre valve. Why do you need to move the pressure cylinder?

wait, what?
it pumps air into a can?
nightmare, that has to weigh about 3 lbs, for $336, no way! what do you do if you use all the air, ride around on a flat trying to pump it back in?
again, this would only sell to people who do not ride bikes.
in the same vein, a generator to recharge the motor batteries... that would sell to the same kind of people...

Yeah, no. Ridiculous. You can buy CO2 cannisters on Amazon for $1 a pop.

Let's just do the math.
C02 Cartridge: $2.00; "Bimp Air" pump: $336.00.
$336.00 divided by: $2.00 = 168, or the number of flat tires you would need to repair before there is any ROI.
I'm just guessing, but that seems like one hella lot of flats!
