@ramzzzzzzz Newtons 1st law: An object in motion will stay in motion unless acted upon by an external force. In the case of the bicycle wheel the external force is wind resistance and friction on the ground. Reducing the weight reduces friction with the wheel and the ground and more aerodynamic reduces air resistance
@jsl47 No no, they covered gravity on the first day.. inertia came later -- and as any dedicated physics 101 student knows, gravity doesn't have any effect on a wheel's rotation, but inertia does. Recall he implied "a lighter wheel needs energy to keep rolling." And as it stands, once rolling, more force is required to slow a heavier wheel than a lighter wheel. And while it's true that rolling resistance increases with mass, the slowing effect is far outweighed by the added moment of mass.
You'll need to make a new video showing the different sizes of rims and the different tyres. I can't find any article or video explaining/comparing different wheel sizes.
things in motion stay in motion. i disagree with you last statement

How is this useless? He's telling us how to choose the right bicycle wheel. Which is what the title is saying..

is there such a thing as a 24 inch road bike wheel?

wait -- "the lighter you can make that wheel... the less energy it takes to keep it rolling."
I guess he missed the lecture on inertia

@skoockum i guess you missed the lecture on gravity. i think that tends to make you use more energy when, say, cycling uphill.

dude this is as useless as expertvillage -.-'

Totally useless advice: Get a wheel with rims, spokes and a hub.
