So you can push a bicycle downhill with no one on it, and it will keep its balance for quite a while, because its front wheel has positive caster, so it tends to steer toward whichever side the bicycle is leaning, thus keeping its balance.
My question is: what happens when you push a bicycle downhill *backwards*? Will the positive caster continue to work its magic, or will it do the opposite and throw the bicycle quickly out of balance?
