Hello Ray,

ok, I tried to estimate the mass distribuition.
The attached pictures show the result:

Stable range from 27 to 56 km/h.

From my experience I would consider P3 as stable
between 5 and 45 km/h. But this is very much depending
on the rider´s practice.

Next I want to do the calculations for my airbike.
This is significantly more stable above 50 km/h.

- front wheel moment of inertia 
The value of 50 in/lbs**2 was for a narrow street wheel, so adjust
accordingly. It is almost entirely a function of rim and tire weight/mass.


How about a 26"x1.75" MTB front and rear wheel?

PS: For calculating the weight of limbs etc:
