Hi Bernie,
I've tried this activity with bikes. It doesn't seem to work that well.
Bike tires just leave too small of a footprint on the ground to allow for
accurate calculations.
If you want to stay away from cars, you might try a cart or wagon with
inflated tires (I know that Radio Flyer has a cart like this). I've never
tried this, but it might work.
-Good Luck
