Thank you! I should make the variables usable for upright bikes as well, I 
think.

Since you have a flevo as well (I think) that would be helpful. If there are 
obvious discrepancies with reality, maybe the coefficients can be adjusted, 
with some further thought. The two main issues of the model are narrow "tires" 
and a pivot without friction or coupling.
Two different authors I read had tested bikes with sacks of weight and no rider 
to verify the general results.

Yes, it appears most (all?) builders are European. When I have some more spare 
time I'll fiddle with the interface some more, but adding a metric display 
option is easy. Maybe a smaller graph and bigger sliders too.
I agree, slug-feet and pound-inches**2 are horrible. There are some good 
resources for equations of bike motion, usually metric, and that is what I 
originally wanted to run as a numerical integration solution.

I also need to find another scrap bike for more parts. 
If I could quit sleeping things might actually get done.
