Hi everyone, happy christmas(adsbygoogle = window.adsbygoogle || []).push({});

I am working on a project looking into the inertial feel of a bicycle. The overall aim of this part is to calculate the inertia of a bike and rider and to consider how this inertia feel can be recreated in an exercise bike and to quantify the differences through testing. In order to do this I need to caluclate the inertia/momentum of a real bike and caluclate the inertia/momentum of a cycling ergometer.

The thing I am unsure about is what is the inertia, (is it a wuantity or is it something that a cyclist feels) and how can it be calclated? Do I need to calculate inertia and momentum for example and how do I combine them. My intial thoughts are:

Frame and cyclist (momentum = mass x velocity)

Rotating wheel and crank (disc) (inertia =(mass x (radius)2)/2

The other issue is that I need to work out the inertia feel of a cycling ergoemter. Knowing that they have large mass fly wheels can I treat this as a disc and calcualte inertia in the same way and compare it to the above?

Thanks for you help in advance, it is much appreciated

Mistry
