Rotary Bike Motor

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.

4200PSI!

Makes ya feel real safe to carry a bomb with you to go bike riding!

High pressure tanks are actually quite safe. They will never just explode under normal real world circumstances.
I know the french have a car that runs on air and if my paintball gun can hurl over 1000 shots at just below 200fps off a single 20oz co2 I don't see why a car or bike couldn't be powered the same way.

Going back to the rotary though I would run it with gasoline mix like it was intended. I've read that they're restricted with their CDI system and it can be easily replaced with one that will allow you to get a lot more than 200watts from that little engine. It should be able to get at least a horsepower with its displacement. I would love to have one myself regardless.

Wonder if rotary is smoother than the kicks of a 1-cylinder piston engine!

Hope so, I'm interested in these too. Would be a nice way to get a legal 50cc but have much more power.

The "rotary" is just a brand name. It has a simple single cylinder engine like all of our bikes, only this one is special in the fact that the transmission is driven directly through the hub of the wheel. It looks like a really bulletproof rig.
If they made a wenkel rotary engine small enough to fit on a bike I'd be all over it. Imagine revving a little 50cc to about 20k rpm all tucked in on a clear road *shivers*

I see. If it was a wankel, it would be amazing! 50cc of rotary is approx 150cc of piston power I would guess. You would have guys on bicycles with 10HP 50cc engines

They are only 1.3L in a car and make tons of power even compared to a larger engine.

Any guesstimate on the range of an MB??
