#2We changed this title to something less baity than the original (et tu, Nature?). If someone suggests a better (more accurate and neutral) title, we can change it again.

#3what was the conclusion ? it's not gyroscopic effects because they still balance with counter-rotating wheels, it's not trail because they can still balance with negative trail. Is it some of each of these effects, if so how much ? What else is involved ?

#4How complex can it be? If you have a bare minimum background in basic physics and control theory, and a bicycle in your hands, the qualitative reasons for balance and stability will jump at you in under 10 minutes...

Alright then, what are the reasons for bicycles being balanced? If it's not anything related to gyroscopic effects, then what is it?

ok, go on.

Please don't post unsubstantive dismissals of others' work to HN.
If you know more than the rest of us, it would be good to post an informative comment that teaches the reader something. If you don't want to do that, it's fine to post nothing.

#8It might help if they program humanoid robots to ride bikes. The problem seems to be hard to analyze because there's a person on the bike, and the way the person moves with the bike is hard to track.

#9Avid cyclist, but I have no idea what this is talking about:
"...the phenomenon of 'countersteering', whereby the rider can steer to the left only by first briefly torquing the handlebars to the right, allowing the bike to fall into a leftward lean."
Am I just doing this subconsciously?

Pretty soon all of human language will consist of phrases like, "You won't believe what happens when this one weird news aggregator changes a submission title!" Is there some way we can try to reverse this trend outside of HN?
