Moment of inertia is a measure of an object's resistance to changes in its rotational motion. It is dependent on an object's mass, shape, and distribution of mass.
Moment of inertia plays a crucial role in bike stability as it determines how easily a bike can be tipped over or steered. A higher moment of inertia means the bike will be more stable and less likely to tip over, while a lower moment of inertia can make the bike feel more responsive and easier to steer.
The moment of inertia of a bike is affected by its mass, the distribution of mass (how it is distributed along the bike's frame), and the shape and size of its wheels.
Moment of inertia can be changed on a bike by altering the mass, distribution of mass, or shape and size of its wheels. For example, adding weight to the wheels can increase the moment of inertia, making the bike more stable.
There is no one ideal moment of inertia for a bike as it depends on the rider's preferences and the type of biking they will be doing. However, generally, a higher moment of inertia is preferred for stability during leisurely rides, while a lower moment of inertia may be preferred for faster, more responsive handling in competitive biking.
