Wacky Wheels

[notme]

Imagine taking one of these in to your local shop to get a new tyre fitted.....could ask them to re-spoke it I suppose....tell them "they all fell out"

They could make that look really good. Shame they made them look all concept like

Bloody good idea, those wheels.

The most efficient flywheels have fuck-all mass in the centre and heaps of mass around the rims.

Those wheels are the ultimate flywheels - absolutely zero mass in the centre - they're nothing but rim.

The gyroscopic effect of those wheels would surpass that of any standard wheel. A motorbike is essentially 2 flywheels/gyroscopes held together by a frame and we use that fact to steer it, keep it upright etc.

I saw something like those wheels on "Beyond 2000" may years ago on an experimental bike but this is the first time I've seen a production machine using them.

Dunno if I'd go for the designs they have, but I'd certainly be up for hubless wheels on a bike.

Wouldn't be that good for handling as it would want to keep the bike upright instead of going to the side and turning. Would make a very stable cruiser though

Wonder why they stopped that "Beyond 2000" show...

Countersteering, unless I'm way off, works because you're turning a gyroscope (front wheel) which causes it to tilt and thus the bike tilts - despite the gyroscopic "stabilisation" afforded by the rear wheel. Surely with an improved gyro on the front, your countersteering would be more efficient.

Physics students feel free to correct me - I wimped out and took chemistry (so correct me politely or get used to checking your ignition systems every day... )

On "Beyond 2000" the test rider reckoned it handled beautifully.

As far as I know, the lighter the rims, the easier it is to flick the bike from side to side because you don't have the gyroscopic resistance. Thats why carbon fibre/magnesium rims are so cool

So if you dropped a bearing at 200 clicks the rim would fall off?
No thanks

[Waylander]

Wondered when people would start putting those on sport bikes.

[ZorsT]

they would look awesome on any bike really.

Can anyone photoshop one for us? (i would but i am no good at using photoshop, and don't have it anyway)

Hmmmm. Thanks for the links. Dymag seem to be making the complete opposite to an "ideal gyroscope" - weightier hub, light rim. I would presume they are doing it for a reason, that it is what the performance riders are demanding.

Blows my theory, big time.

Also very polite, alarumba - you can start your vehicles without fear...

[ZorsT]

I thought the lighter the UN SUSPENDED weight, the eaiser it is to flick around?

[Coyote]

I'm just going by what I've read and been told

I'll save up for a set maybe. Could get a F3 bike for the same money though

Bit pricey. Would be interesting to see how it effects your bikes handling and performance

Awfully tempted to save up for a set. Not sure if streetstock rules would allow them



These ones are for the GP125s so should fit my CBR. A front rim weighs 2.2kg!
