Maintaining a low center of gravity is crucial for stability while cycling. When a cyclist keeps their center of mass lower, they significantly enhance their control over the bike, especially during turns, descents, or in challenging road conditions. This position helps distribute weight more evenly across the bike, improving traction and balance. A lower center of gravity allows for better maneuverability, enabling the rider to respond more effectively to sudden changes in terrain or obstacles.
In contrast, the other options can compromise stability. Riding too fast may reduce control and increase the risk of losing balance, especially in turns or when navigating rough surfaces. Keeping both hands off the handlebars can lead to a lack of control over the bike, as hands are essential for steering and stabilizing. Over-using the brakes can cause abrupt changes in speed, which might destabilize the bike and throw the rider off balance. Therefore, maintaining a low center of gravity is recognized as the best practice for stability while cycling.
