has anyone seen this?

I saw this a while back, lost it, and found it again tonight. The thing is, they still haven't started selling them. Here's the link:

RevoPower - Motorized Replacement Bike Wheel

Looks revolutionary and retro, with the engine spinning around the fixed shaft like the radial cylinder design. I might have read the spec sheet too fast.
No idling, could be good or bad depending if you're going uphill or downhill.
I like it!

On second look its a fixed motor. What a great idea!

Nice idea but no idling... engine too small for my requirements... :-(

Guys, from an engineering stand point:

This is a classic example of smoke and mirrors. Look through the site, (it is nicely done), and find one shred of evidence that this will actually work as advertised and at a price that any one would be willing to pay!!!

The first person to show me I'm wrong get's a free clutch actuator...The first person that tells me WHY this won't work, also get's a free clutch kit.

Now for more fun...I just have to do this because I've seen so many awesome websites that portray revolutionary products that aren't even remotely realistic.

The T/C engine is a classic example of computer technology run wild...(Smoke and Mirrors).

The inventor of the T/C engine called and asked that I download the files and quote a prototype of his engine...He found me through the B.R.E. website. I looked at his 3D CAD files and realized immediately that there was no way this was going to work. I called him back and asked him if the engineering had been finalized...Oh yes he says, just quote the parts...O.K. no problem. My quote was 98K. He says great!, now can you guarantee it will work!!! Of course NOT, you said the engineering was done...I'm just going to make the parts!!!

Look through this site...the first person to figure out why this engne will not work, will get a clutch kit and the product of thier choice! Billet this, billet that, you decide.

(Don't look for complicated stuff...the web site is nice but the engine is horribly flawed)

Hey, what a great idea for a scam. Dream up something revolutionary that looks plausible, but can't really be accomplished. Instead of spending millions on R&D, just do up some great drawings, hire someone to "build" it...someone with assets.

When it doesnt' work, sue him out of house and home. Voila. Got house, home, and the shirt of his back for the measely sum of 98K.

Luckily our local Clutch Meister didn't just fall off a turnip truck!

Good story Jim.

Maybe Revo Cyles there should team up with Moller to make a flying bicycle that's computer controlled by a palm pilot!

I think it wont work because of the way the motor sits inside the wheel. First I believe the motor is too big to ft inside a standard wheel, what with the carb, clutch and all the other little stuff that goes with any motor no matter how big or small it is. I also can't see the motor staying stationary while turning the wheel around itself.
Just some guesses after a long day.

really I'm just hoping I get lucky and win a clutch kit as my clutch has been acting up since I got the motor and I can't afford that nice clutch kit.

Yup, I also think it won't work. When the wheel spins with the engine, there is a centrifugal force, so it would be very difficult to regulate the fuel flow even with a good carburetor, unless the carburetor is mounted outside the wheel, but then you have to solve the problem of intake leaks. The fuel line or intake manifold has to be dead center inside the axle. Also, with the centrifugal force, it would mean all the residual oil and carbon would accumulate inside the cylinder. I don't see any smoke from the engine in their video. I think they used an electric hub in the demo video.

For the T/C engine, the airflow is blocked on the other side. How would the air flow? and the spark plug fires outside the cylinder, then the piston and crank is pretty quite useless. And for the engine to have a rotational force, it has to be eccentric, like the rotary engine in Mazda or the rotary compressor in airconditioners.

Is Creative engineering really serious about this clutch actuator?

Well I got several reservations about it. One, it's only 25cc. Two, the engine is spinning with the wheel, how would the fuel get to the carb? Three, with out a fuel pump, the fuel would have to be gravity fed like on a traditional motocycle or a chengine motored bicycle so where is the fuel pump?. Four, how would the engine get consistant fuel from the carb with it spinning?

the motor is supposed to be stationary, not spin with the wheel but spin the wheel around itself. I just don't see how that could work though.

Okay I watched the video's and stared at that one pic with the engine all exposed.
I see the fuel tank is on the frame where a water bottle would normally go. I also see that both the fuel line and the throttle feeds thru the axle.
I don't see a spark plug wire but see an exposed spark plug. Right there I would have to question this. Unless it's a small wire that needs to hug stuff so it don't snag. I see what appears also to be a very small engine.
The intake is covered up the exhaust looks like it also serves as a counterweight.
Aside from the lack of a spark plug wire and the questionable how does the fuel get to the engine although a fuel pump can rather go in that intake enclosure,you got me stumped cause the riding video's under gallery and video's show people actually riding this thing.
