and even hardcore scientists find it difficult to model the bicycle. So I'll go with "magic".
I didn't know what group of people might be trying to model this. Basically I remember almost nothing of the radio programme other than that I was stuck on the M621.
the force propelling the bike in a forward motion is greater than the gravitational force pulling it to one side/down
cut it out with the fancy talk.
would have nothing to do with the vertical force.
I reckon it has something to do with the cyclist pushing on the pedals, which is why it's a little easier to stay upright whilst still if you pedal backwards.
due to the rigidity of the bicycles frame
pedalling backwards serves only to keep the riders weight, and thus the bikes, central
and it, er, helps keep the magic moving through the bike, too
an up to date scientific paper describing the magic
I haven't read it yet but I thought I'd just cut out the tedious and embarassing part where I try and comprehend something.
to keep balanced, you need to keep your centre of gravity above the bike frame, and on a bike you can turn the front wheel; and when you're moving, this will correct your centre of gravity, but if you're stationary, you have to move your body to correct your centre of gravity.
It's actually balancing itself by wobbling left and right as it moves and this pendulum like motion means it doesn't fall over until it wobbles too far one way or the other.
Technically a bike might be able to stand perfectly upright while still but it would mean a perfect point.
Just consider how much you move to keep yourself still if you stand on tip toes or one: balancing without moving at all is very tricky.
no blood left in his head.
You're so Richard Herring.
I was only musing last night whether it was racist to call a chinese take-away a 'chinky' any more? I bet it is.
How do you make a cod roe?
I just think about it a lot.
Draw pictures of it.
Ocassionally write poems about it.

And let's face it, I should know!
But the curvature of the front forks helps lots too.
