"A much shorter chain goes from those cogs to yet another cog, mounted on an arm that extends from the head tube. A flexible universal joint connects that cog to another one, that is mounted on an arm that is attached to (and that turns with) the front fork. Finally, a third chain extends from the cogs/universal joint down to a drive cog on the front wheel hub."
I assume that 29,800 is the price in Japanese Yen, which works out to $250 or so, which seems reasonable for the type of bike it is.

Well now I want to give one a ride. It would seem the extra gears and chains would just cause the bike to lose efficiency and 2wd would not in any way make it do anything better since your input power is the same, but idk

With cars and motorcycles, the performance is oftentimes limited by traction, so having extra wheels improves the traction and off-road performance.
With bicycles, you very seldom are limited by traction, and usually be lack of power, so adding the 2-WD increases weight and complexity, but doesn't necessarily help performance that much. If you got in just the right circumstances, it'd be great.

I guess the other thing i was thinking about was that both wheels turn at different speeds which could cause some potential issues..

Not sure why that would be, since the rear wheel drives the front at a 1:1 gear ratio. I suppose there could be a problem if different size tires were used in the front and rear.

Hmm.. I suppose that is true -- In the vid it kinda looks like the front wheel was spinning at a different rate than the rear when he was demoing the drivetrain.

If that were in fact the case, then at least one of the tires would be skidding, which would completely defeat the whole purpose of the setup. Anyways, it's just a lot of unnecessary complication and added weight with no real benefit.
