Actually I did not separate wheels inside the Blender. Whenever you import FBX with multiple props attached to an empty root it is asking if you want to separate them. Which it does and it's still does not work.
So yes, it is a bug. It was fixed before, when 3DX had that same problem. Hopefully it'll be fixed for the direct FBX import.

Hm, don't know if you mean "detach" the wheels from the bike, but that made no difference...
Anyway, as I am no tech guy at all, I am glad 4u2ges made it work now.
And I also think this is a bug, that appeared a long time ago and now raised again.
Yesterday I imported that "Hard Tailed Rat" bike (OBJ) via iClone due to automatically "sub-propping".
The problem occured...
Now I imported the "Hard Tailed Rat" bike (OBJ) via 3DX and the wheels behave normal...
Thanx for trying to help anyway!

ah okay that makes sense.  I was scratching me head.  Because the thing needs bones to recognize so you can rotate things on their own.  So there is two ways to do it.. put bones in inside blender or leave everything seperate and 3dexchange puts the bones in.   So that's the bug.    The 3dexchange is not putting the bones in so you can seperately move things.    

Now i get it ^^ 
see me i put all the bones in inside blender and avoid that issue so would never see it.

since the 3dexchange is not recognizing things as it should yes if you chop up the bike into the parts you need and then import all the parts seperately into iclone and put it together it will work as a workaround since it seems 3dexchange has stopped putting in bones if you tell it to.  

Guess I should add since this all started with the unable to do the 360 thing.  Once the object has been seperated and each piece has now a bone if it starts to do that go and change the rotational axis (which can be done inside iclone) because that is gimbal lock and the way around that is to simply change the axis of rotation and then it wont lock.   (since iclone is putting them in as root nodes its going to be jet straight )

FYI

As per Molly from RL (at FT here) there is a workaround for now (you have to have a Curve Editor plugin):

- Right mouse click on the prop at the stage (or transform track at the timeline) and then Curve Editor > Convert to Curve Data. Prop can now be animated beyond 360 degrees for rotation.
- If Rotation Order selection in Animation menu is still not available, select any other item on stage and then select back the converted prop. Rotation order in now editable.

Thanx for info! ;)

Sorry to here all the "Trouble" with Reallusion/IClone , Rotation, I Still use Iclone 4 and Icone5, And Transfer it into IClone 7.I make all the adjustments, and Rotations before adding it to I-7. If your trying to Use Pre-Props (Rotation) On the  Props You Downloaded, It Does Not Always Work!!! Remember Reallusion is out to Make Money, Sometimes they get ahead of themselves. I do not Know if you Can Still  Get I-4 and I-5 If you can, It Works Great.!, Reallusion Still has a Lot Of Bugs in their System .Here Lately, Their having Problems With Content Uploader. Take Care,

They way the 3dexchange works is that normally when you tell it to keep things seperate that translates into "put in a bone for each seperate piece".    Once upon a time lonng ago the 3dexchange did not seperate things it was an added feature.    But every once and awhile they forget about the feature and so need to put it back in that's basically what this amounts to.  So since static props that were meant for set dressings and never meant to move are just that static there is no way of knowing how they are constructed.    If its part of a continuous mesh it can't seperate the thing logically no matter what method your using.  If its something like a car or a bike wheels etc are seperate often created from primitives and just customized.     

soo what is going on is due to loss of a feature that was added.  Hopefully they will fix it.   But for now the solution is to break up the model and import pieces seperately so that a bone is added for each piece and then reassemble it inside iclone or use several copies of the model and change the rotation of the entire model and hide the extra bits which is awkward and takes up tons of memory real estate so probably not a good way.    If you can't break it up because its just one continuous mesh then no method will work cause it can only work on things that are made up of several independant parts to start with.  

Anyhoo that is what is going on.
