just looked at the product and from what i can tell its a simple gearing box. so as I understand
You're traveling Half the distance, but TWICE as much effort to travel the distance. its a swap.. 1/2 distance, x2 the effort. and PS has nothing to do with this as far as I can tell. PS will work the same as before, its taking the Output of the box and putting it to the wheels. the EFFORT you're exerting is going into the box. so in conclusion. picture turning ur wheel 1/4 and multiplying it by 2. (i can turn my steering wheel with 1 finger.. now i have to use 2 :naughty: )
