Rotary Bike Motor

IMO,

Way too expensive

Underpowered

If you could run on compressed air, why would you want to?
 
I've ridden one of these bikes & it's a nice engine & legal.............but gutless.
 
That's like a modern day Honda Cub Type F!

Never happen, not enough energy stored in a compressed gas cylinder. This is pure bunk, you'll be dead and gone and never see it a commercial success. Stick to good old gas, plenty of BTU's per lbs.

I will respectfully disagree. Utilizing modern carbon fiber reinforced tanks, air storage at 4,200 lbs/sq in is quite feasible. At that pressurization level one tank about the size of a scuba tank will readily power a motorized bicycle a quite reasonable distance.
 
Check out on YouTube......
ok....but mention youtube, and I lose myself in there for an hour, minimum.... heh heh ;)

the 1st two video links are relevant to what beachcruiser is talking about.

Would BIG Oil allow this to succeed?
