Bicycle – Bartosz Ciechanowski

This interactive article by Bartosz Ciechanowski delves into the intricate physics of bicycle operation. It covers fundamental concepts of forces and moments, the mechanics and design of bicycle wheels, and the structural stresses within the frame. Through various demonstrations, the article explains how bicycles accelerate, brake, turn, and maintain stability, including the roles of gyroscopic effects and trail geometry. It aims to make the complex interplay of these forces tangible and understandable.

Note

i had to pause reading this multiple times to actually inspect my bike and see parts that i needed to more fully appreciate.

my spokes are much more complicated than i thought and my frame has so much more meaning to it now.

this was a difficult one to get through since so much of discussion of forces is not only "invisible" but it is also so granular.

i definitely have a lot more to appreciate on my next bike ride.
