That picture is not of a two wheel drive bike nor one with disk brakes or any front wheel electric assist. But of course that may not be a picture of the actual theft.

I was going to post my Yahoo link. But you beat me to it Andy!!!!!!
https://www.yahoo.com/news/military-prototype-bicycle-worth-100-210001074.html

I'm not sure why its $100,000 either. But maybe there was some 1996 secret military weapon on it. Like lasers! For aiming guns anyway, not for blowing things up like Star Wars. Or radio controlled airplanes! What are those called, drones? Or maybe it was so high tech it had INTERNET!!!!!!!!!!!!!! And you could send emails while riding your bike!!!! And it had this wild and crazy idea of a portable telephone you could just talk to and tell it to call any number you wanted!!!! Or maybe it was as prosaic as having a V cradle built into the handlebar so you could rest your gun's barrel and fire full automatic as you rode down the road. Or maybe there was a mortar mounted on the front rack and a mortar shell carrier on the back rack. So it was easy to fire mortars as you pedaled.

"two wheel drive bike"? Who mentioned a two wheel drive, or all wheel drive, or both wheel drive bike? Is that practical or needed on a lightweight bicycle? The bike weighs 25 pounds. Rider weighs 200 pounds. 80-90% of the rider's weight is on the rear wheel. How much benefit is front wheel drive on a bicycle? Its not like small compact cars where the majority of the weight, the engine, is right over the front drive wheels.

"disk brakes"? Had those been invented by 1996? If they had, it was probably still early in their lifespan. So no point jumping into a new unproven brake method when the old rim brakes had worked for 100 years already. Kind of like the military still uses diesel engines. Just stick with what has worked for 100+ years now. Don't reinvent the wheel until you have to.

"front wheel electric assist"? I guess that sounds nice. Sort of. But how would a driven front wheel help when almost all of the weight of a bicycle is on the rear wheel? I suppose it would be fun to pop a wheelie and have the front wheel keep turning.

As for not being a picture of the actual theft. There are words on the screen describing the thief. And the description matches the person shown in the video. So I would guess it is actual video of the theft. But I'm sure Tommy knows better.

Disc brakes go back a long way. Shimano from mid-1970s here:
http://www.yellowjersey.org/shdisc.jpg

Two-wheel drive gets reinvented regularly but never sells.

Front hub electric motors are not at all unusual. That was
the standard 'electric upgrade' format in the 1990s.

OK. That makes some sense. Because it would be very easy to ADD an electric/battery powered front wheel. Just slap it in the dropouts and turn it on and away you go. But I still stand by my comment that it may not be too helpful because all of the traction for a bicycle is on the rear wheel.

I question your wheel loading figures as years ago I actually weighed
the wheel loading on a conventional, steel, road bike and it was very
near to 50%/50% with the rider in the normal "top of the bars" riding
position, on a level surface.

Thus, an electric front wheel does make at least some sense.

If its 50-50 weight distribution, then why do rear tires wear out. And front tires never ever wear out. You can ride front tires for a decade and it will be a lot closer to new than used. I know the rear tire has the acceleration aspect. But I don't think too many people leave rubber marks on the pavement when accelerating. And the front tire does have the extra wear of turning. You scuff the tire on the pavement every time you turn a corner.

I might maybe possibly be exaggerating a little bit with 80-90% rear weight bias. But 70+% is probably very accurate. Now I can believe a professional racer does get to 50-50 in the drops and his stem and the bars pointing down at the front hub. But Sunday tourists sitting straight up and down with their bars raised higher than the saddle? Hard to believe.

Well, all I can tell you is that I sat the bike up on two bathroom
scales got up on the bike, pedals level, my normal hands on the top of
the bars and leaning forward a bit, and had my wife hold the bike
vertical and read the scales.

Now then, obviously it does depend a great deal on the weight and
weight distribution of the rider and, of course his position on the
bike. A rider with a "fat ass" for example puts more weight on the
rear wheel while a (would one say) "more athletically designed"? body,
slender hips and wide shoulders will obviously apply more weight to
the front wheel. And, of course, seat tube angle makes a difference
But 80-90% of the weight on the rear wheel?

I just checked my touring bike. 41% front, 59% rear, and that's with a
handlebar bag containing a few tools, gloves, etc.

Rear tires wear more because they are applying the driving force to the
road and receiving the forward reaction force from the road. This
involves constant microscopic abrasion.

The rubber in contact with the road gets flexed in the forward direction
from the road's forward force, then snaps back as it loses contact when
it leaves the pavement.
