Question

When you turn while riding a bike, you must lean in the direction of a turn or risk falling over. If you lean left as you turn left, why don't you fall over to the left? The torque produced by leaning left counterbalances the torque produced by the tires on the ground, so there is no net torque about the center of mass. You don't fall over to the left because the momentum of the bike is to the left. The torque produced by leaning left is what causes the bikes to rotate as it turns to the left. The torque produced by leaning left counterbalances the torque produced by the ground on the tires, so there is no net torque about the center of mass.
