My BioTrak bicycle tank last year weighed 800-1000 lbs yet 1 person in 1st gear could easily move it (at around 1/2mph). I kept it in 7th gear most of the time, that felt about right (and speeded it up to about 1mph).
My original analysis went something like this; on a mountain bike, a 200lb adult rider can move 25mph. So a 1000lb load should move at 5mph. From experience I would estimate losses for a tracked vehicle to be ~50%, wheeled vehicles do not have the same issue.
So, if you have a 2000lb art car, 2 bicycles should be able to move it if geared properly. 4 bicycles should allow you to add a few passengers. 6 would allow for easier pedalling. Of course, adding pedal power to a car is crazy, since you have alot of extra weight that is not needed in a car - building a custom frame of lighter steel would be better.
