Those 2 tanks really kill the idea of a grocery getter. Where to store stuff?
I was wondering if they can build a self sustaining compressed air bike. As the bike moves, somehow the wheel can run a small compressor to keep itself going.
Also, how much psi do they need to fill those tanks? Not everyone can afford their own compressor and most gas stations, around here, charge for air and these things barely get the job done.
Just some thoughts.
