That Bicycle post is Pulitzer worthy - every middle school student should be taught that post in science.

As a cyclist for decades - I still learned a lot - how to put to words that which I had innate muscle memory knowledge of, but no language for.

The demonstrations are fantastic.

Hands down should get some sort of IRL award of meaning.

I forgot I had seen the watch as well... Man this guy is amazing!

Thanks for resurrecting these for me.
