# Why does bike trip on the opposite side when turning the handle?

It can be observed on a stationary bike and also on a moving bike that on giving a jerk on the handle the bike leans to the opposite direction in which the jerk is given. Is it due to angular momentum, directional inertia or some other phenomenon is applied here? Or it's just due to design of bikes to easily shift centre of gravity?

(I want to make it clear this question is not about countersteering although the same thing happens for a fraction of second while countersteering)

When you turn the front wheel, its center and, therefore, its point of contact with the ground, shifts in the direction of turning and becomes misaligned with the plane of the bike, which becomes more obvious, if you turn the wheel by a large angle, say, $$90^{\circ}$$.
