Cool idea, but what caught my eye was the “no emission” lede. Er . . . how does the compressed air get compressed in the first place? Unicorn farts?
To: Red Badger
Fortunately there are chunks of compressed air just sitting out their waiting to be crammed into tanks so you don't use any energy at all running this. < /sarc>
I want one powered by compressed carbon dioxide made from burning spotted owls.

Not bad for a proof of concept at least.

Zero emissions? Really? That air magically compresses itself. Idiots.

So whats the range on this sort of a thing and what kinda psi do the require it be pumped up to. I just can’t see it going very far.

Energy is required to compress the air. That probably comes from fossil fuels.
To: Red Badger
The drawback is lack of refilling stations, and a need to find power to compress the air in the first place Nice bike but there are no free lunches.

Another “green” example of displaced benefits. While the bike itself may not pollute, the energy expended somewhere else to compress the air will pollute (unless it’s hydroelectric or nuclear). Is the net efficiency of using air to power this bike greater than the bike burning fossil fuel directly, instead of at the power plant? Doubtful.
To: Red Badger
Still requires some form of fossil fuel to compress the air.
They’ll never learn.

Yeah, let’s see this clown try and get DOT approval for that scuba tank.
It would make for a pretty spectacular wreck to see that bike hit a truck and puncture that tank.

Another NON-technical person that believes that pressurized air is free to the consumer.
However, what happens is that the air-tank is both pressurized and heated simultaneously. But as the heat leaves the tank (by internal radiation heat that leaves the tank) Once cooled, the compressed air delivers far LESS pressure because the heat is gone.
The bottom line? You won’t make a gain AT ALL. You can only hope that you could use-up the tank before it cools. But on the other hand, you should find another method to make energy.

You could pump the air using solar energy.

Pretty interesting. I don’t care about the ‘green footprint’ nonsense, I just think that fluid power as an energy storage medium has a lot more potential than we think. Eaton and Parker Hannifin have both developed hydraulic hybrids that use braking hp to store fluid power that is used to start the vehicle moving again - perfect for things like garbage trucks and delivery vans. A French company was working on a compressed air-powered small car, but this in a moped form would seem to be very useful too.

http://biobug.org/scuba/scubatank/ calculates the energy in the compressed air in a scuba tank.
So for a 230 bar 12L tank we have 230*12*450 Joules. 1,242,000 joules! But gasoline has 34,200,000 Joules per liter, so a 12L scuba tank has the same amount of energy as 1.23 fluid ounces of gasoline. Woo-hoo!

Just to play devil's advocate here; pneumatic motive power does have some advantages.
* If you're in a hot climate, you get "free" cooling, from the release of the expanding air. OTOH, if you're in a cold climate, you don't get this benefit and you still have to figure out how to heat your vehicle.
* The refills would be quick -- quicker than any solution proposed for battery-electric vehicles. Or, you could have slow refills using a small compressor at home.
* Regenerative braking could capture a lot more energy than is possible in an electric vehicle.
* The article mentions powering the compressors by using wind or solar power. That could be a way of making some use of the wind power or solar power that is produced when it's not otherwise needed. Of course, that requires an assumption that wind and solar power are inevitable, regardless of financial or other considerations.
* Compressed air tanks have greater energy density than batteries -- i.e. they don't weigh as much.
