Re: [Phys-l] Bicycle question

Isn't this essentially the same reason it's harder (takes more force) 
to turn a corner when you're going fast (greater linear momentum)?
In this case it's angular momentum (sorry Sam). Tipping changes the 
angular momentum of the wheel and so requires more torque when the 
wheel is turning fast.
