I'm still trying to figure out how my bike works myself.

As far as I can tell, it's a miracle.

I've taught LCI classes and one of the hardest things is teaching people how to do a counter steer or quick steer which involves exactly what they are proving.

Sorry, I posted that based on the thread title, not the video (which might be "how bike steering works.")

I bet more than half the population of the world doesn't know how magically incredible it is to lock together two nuts on a bolt. That's how a bike works.

I really like both of these videos. I went to a bike fair in Luxembourg once and this guy had an opposite-steer bike like the one in the second video from P!N20 above. You may have seen these before, but it's basically a regular bike but when you turn the handlebars the wheel turns in the opposite direction through a clever gear linkage. It ends up proving the same thing, and also making you feel like you're drunk on a bike. It was more a study of how we learn and can unlearn cognitive bias and function. The most interesting part for me was at the end where he has to re-learn how to ride a normal bike.

Once over the critical velocity, I can steer without touching the bars but at slower speeds, counter steering with the hands is absolutely essential.

Neat. In a physics sense, riding a bike really is like magic.

They had me until the end with the "better bicycle" stuff.

Why does a machine that almost feels like magic and is proven to self-correct when pushed down hill with no rider need assisted steering? Does the time-tested design really benefit from that "improvement?" Does that bit take away from the point that there is an intuitiveness to the design as is that is part of its value?

Retroactively explains (alas, but doesn't change) my last bike crash: My body going over and slightly beyond the bars (I was essentially a unicycle at that point) put the weight out front of the pivot point and self-steered until going over the edge and into the ditch. Funny in a not-so-funny way

This is precisely why some of long-term bicyclists have trouble riding a tricycle. When I got on my friends pedicab, he warned me that some people (myself definitely included!) have the leaning and countersteering thing so tightly ingrained that they have a lot trouble making the pedicab turn, even though it is, in that case, a simple matter of turning the front wheel in the desired direction.

This is probably why I fell off my bike during Cino...I was doing it wrong!

Come to think about it, I fell off my bike during Eroica Gaiole too. This problem goes way back.

I’m sure there’s an explanation using force vector arrows and what not, but I’m amazed every time I ride and the bike doesn’t fall over within 20 feet of starting.

Oh, there is, along with some control theory based on a wet neural network. I've seen it through enough to just want to ignore it all and just say "it's magic." More fun that way.
