Tandem Bikes
(OP)
Could someone help me with how 'Independent Pedaling System' in a tandem bike works, there are two mechanisms I know of, the Da Vinci's tandem and the Afar IPS. I know that coasting is possible with the free wheeler or the uni-directional bearing that they have used, but how is Independent pedaling possible???

You want to be able to coast with one and still pedal with the other?
I have not seen this and not sure if possible.

Are you buying a bicycle or inventing a bicycle or what?

If it is a single cog freewheel you can coast or peddle independently but both riders have the same gear ratios. If the freewheel is multi-cog with a derailleur then both riders can choose separate gear ratios also.
Yes, it is a lot of chain and hardware, but it works.

Maybe this will steer him to at least creating a clear explanation of the goal(s):
