Stumbled across this - interesting demonstration of bike steering

Interesting!

Basically gravity is your friend.

Though I still think it hurts sometimes. Lol

That was all kinds of weird. Worth a watch though!

I wonder how it would steer if someone who had never ridden a bike went on it.

A lesson learned from riding motorbikes with sidecars is that the automatic steering reactions you have for a motorbike are all wrong when you get on a sidecar.

You have to learn a whole new set of automatic responses, and counter-steering is not one of them.

A sidecar is just an asymmetric tricycle. It isn’t to do with habit, it’s because of how the action of steering laterally displaces the contact patches, generating a lean angle, independent of how the rider shifts their own mass.

Agree, what I am pointing out is that an experienced motorcyclist has all the wrong reactions for a sidecar outfit* - at least initially.

Thus would someone with no riding experience actually do better?

(*Speaking from practical experience here, 3 crashes in 8 miles on my first outfit when I was an impetuous youth 🙂 )

For a sidecar, yes possibly.

For the bricycle, no, it's genuinely unsteerable, in the same way that no amount of wiggling achieves a lateral movement of the zero gravity pendulum.

That's genuinely interesting, but makes my brain hurt.

Yeah, I think that the that starting point of something that allows you to lean at any angle without falling isn't very natural which makes the results of riding it unintuitive.

That looks like you have to lean the opposite way to steer around the first cone but you're then stuffed for the following cone.

That's brilliant.
