AWD bicycle part 2

Another AWD bicycle design that comes from my home province of Quebec. It's chain driven and it's weight about 45 pounds. The manufacturer said that it is used somewere by soldiers in the desert. The design is not as clean as the one that have been previously discussed. I don't know if this design could handle a full-suspension setup. The point is still if a driving front wheel is needed. Cycling puts so much weight on the rear wheel that gives it a lot of traction. A little bit like front and rear braking, the former being way much more efficient.
