Friction
Friction between the tires and the road surface prevents the cyclist from skidding away. This friction allows the tires to grip the road and provides the necessary traction for the cyclist to maintain control while braking or turning.

The friction between the tires and the road surface is what prevents a car from skidding. This friction helps to maintain traction and control between the tires and the road, allowing the driver to steer and brake effectively. Factors such as tire quality, road conditions, and driving speed can all affect the amount of friction available to prevent skidding.
The force applied by a cyclist is called pedaling force or pedal force. This force is generated by pushing down on the pedals to propel the bicycle forward.
A bike skidding on a road is experience kinetic friction. This is a dissipative force, in that it takes energy out of a system when motion is in placed and puts the energy into heat.
When required they drive with chains on the wheels, this stops them skidding on ice.
it is the force that makes it skid when sudden breaking.
As a cyclist goes faster, the force of friction remains relatively constant. The force of friction between the tires and the road depends on the coefficient of friction and the normal force, which do not change significantly with speed.
No, the forces acting on a cyclist when decelerating are not balanced. The force of friction between the tires and the road, as well as air resistance, act to slow down the cyclist. The net force in the direction opposite to the movement causes deceleration.
A cyclist needs to exert a centripetal force to move faster around a curve. The amount of force required depends on the speed of the cyclist, mass of the rider and bicycle, radius of the curve, and coefficient of friction between the tires and the road surface. A higher speed or tighter turn will require more force.
If a cyclist turns around a curve at fifteen miles per hour and then doubles their speed to thirty miles per hour, the tendency to over-turn increases significantly. This is because the centripetal force required to maintain a curved path increases with the square of the speed, which can lead to a loss of traction and control. At higher speeds, the centrifugal force acting on the cyclist also increases, making it harder to navigate the turn safely. Therefore, the risk of skidding or falling off balance becomes greater.
