Powered Unicycle Wheel

[dunebugmi]

Does anybody know of a mod that includes a powered wheel that is not designed to be attached to the side of a vehicle, but instead underneath or in front?  An example would be a powered wheel for a unicycle or motorcycle.  What I have in mind is something like the stock landing gear with a drive motor built in.  

Thanks,

I found some landing gear with powered wheels.  Also some other wheels and tracks that would fit this purpose.  Most of them were in the Kerbal Foundries mod.
