How do you put this on? Is it tricky or difficult for a non-technical person?

It's easier, actually, than putting on your rear wheel. Just get the chain in the roller wheel of the device, slide it into the rear chain stay dropout, then lock the quick release lever. If you want more or less tension in the chain you can simply adjust your rear derailleur to lower or higher gear and rotate the crank.

i have one. no need if you have a thru axle. simply use an old adhesive bandage spool and your thru axle. I use mine mostly for transport

That would definitely work too!

Is there a bearing in the contraption, or does the plastic wheel just spin on the axle?

No bearing; although, otherwise well made. The plastic wheel spins on a metal axle. The chain rides on the plastic wheel which is free to move sideways when shifting gears. This makes it easier to clean the derailleur linkages as well as the chain.

Will it work on my 6KU track bike?

Probably. It's designed to work with quick release axles. Your bike as bolt on axles. It will not work with thru axles. It is adjustable for the thickness of the drop out. If you still have the factory bolt on axles , you'd have to undo the bolts with a wrench, remove the rear wheel and then use this hub. To put the wheel back on, you'd do the reverse. If you're not familiar with the terms "quick release axle", "bolt on axle", "bicycle drop out" a quick search of Youtube should help. You could also show take your bike to a local bike shop, show them a pic of this item and ask them if it would work.
