Wow... They sure talk about gyroscopic forces a lot on their site, but it would seem to me that by counter-rotating the rotors you're eliminating the effect of a lot of the gyroscopic effect of the wheels. Actually, that's their entire point. Doesn't that seem to anyone else that the bike would become incredibly twitchy and difficult to handle though? I mean, I don't think I WANT my bike to turn like a 125cc GP bike going 20 mph when I'l doing a buck twenty!

Hmmm. How much is this going to weigh?

Sounds like it might be worth the gain in unsprung weight - but we'll see.

It seems like they have a theory and little else.

They're keepin it "secret"...

I just can't see them fitting the gears needed to reverse the rotation in a space small enough to not have to make the rim hub larger...

well, im not sure either but they do have a patent on it:

well, it's a bit more than a secret now:

Wow, that is really cool. So how long until we see them on the track and in showrooms?

I have seen bicycles with a counter-rotating weight to cancel out the gyroscopic effect of the wheels. It was impossible to ride. If you lose the gyroscope, you are essentially trying to balance the bike at a stop.

No thanks. I can barely do it on a bicycle.

Anybody can write a press release.....these guys just seem to have forgotten Newton.

All they are doing is increasing unsprung weight, which makes them feel more confident in corners.

I'm skeptical about a lot of what they write, though the reality of their idea, I could believe.

Rob, how would increasing weight anywhere make it feel easier to flip the bike from side to side? That doesn't make sense.

I never said that it made the bike feel any different or that it made the bike easier to flick. I am willing to bet it does nothing but slow the bike down. (And going slower would make them feel confident....)

I am willing to bet that the riders involved in this "theory" totally believe that what they are doing has results. But throw a rider on that has no attachment to the project and you will probably get different answers....

The pshychology of believing in something has astounding results. Getting true and valid testing of any product is key to understanding what it does, they are nowhere close to this at all.

I am pretty sure they could sell quite a few units without ever testing, heck they might even sell the design to someone. That being said, don't look for testing anytime soon.

Not Rob and hoping not to sound like Googlepoet but...

By reducing the gyroscopic effect the bike will be easier to turn. That is why it is easier to lay the bike down going slow v going fast.

Lighter rims accomplish the same thing by reducing the mass that is rotating.

I still think this is a very bad idea.
