I am curious how to estimate drag for a bicycle. This has two different framings: Find the amount of power required to ride at a certain speed. That is, when one is traveling at a constant speed, ...
What exactly are they measuring? How do they measure it? What are the implications of the different approaches on accuracy / speed of getting a good measure? It would be helpful if someone could ...
I am trying to calculate the power needed to hold a steady speed on an indoor trainer, so as I can train using power in watts. I set the bike up and put the crank at 90 degrees, then put a weight of ...
