Center of gravity of Bicycle

Hello,

I would like to know where should be the Center of gravity of a bicycle?

Also with equations can one please explain its stability.

I had gone through many articles on net with one shown as reference.

If you have problems with your equations it would be necessary that you attach you Mathcad worksheet to let us see where we can help.

With a man?

Yes ,

With a man and prior to that for designing purpose, without a man.

But ultimately i wish to learn its balance.

Some articles suggest having a CG higher gives stability while riding faster.

Some suggest CG should be lower for better balance....

Considering centrifugal force and tire friction into account, i wish to design best bicycle.

But if some other aspects or approach exists, i would be more then interested to learn.

Thank you for your time and considerations.

I think that these materials will be useful for you:

1. Article "Linearized dynamics equations for the balance and steer of a bicycle: a benchmark and review" (you can also find this article in attachment) by J.P. Meijaard, J.M. Papadopoulos, A. Ruina, A.L. Schwab: http://cycleseven.org/wp-content/uploads2/Mejinard-et-al.pdf

2. Book "Bicycling Science" by David Gordon Wilson: http://books.google.ru/books?id=0JJo6DlF9iMC&pg=PA263&hl=ru&source=gbs_toc_r&cad=3#v=onepage&q&f=false

Though Linearised dynamics equations for the balance and steer of a bicycle above is a good article please give a look at following link which i came across today 08 AUG 2013.

Please do help me find the correct answer with your valuable suggestions.

What ever your theory , just give it a try here, we will try to discuss and expore upon an idea.

Points to be discussed are...

How a Bicycle works.

Where should be its CG

What are the forces and couterforces acting on bicycle.

Thank you for your time.
