How is Friction Harmful When Riding a Bike

how is friction harmful when riding a bike

In school, we learned that friction is a force created by rubbing or colliding two surfaces. But when it comes to biking, friction is a fundamental force governing how a bicycle interacts with the road surface, providing stability and propulsion.

However, it is also essential to learn that friction can pose challenges and hazards for bikers. But how is friction harmful when riding a bike? In this article, Let us discover the potential harm friction provides when mismanaged on the road.

Loss of Traction

Friction provides the much-needed grip between the bike’s tire and the road surface for traction. However, there are situations where improper friction application can lead to a loss of traction. Overbraking, cornering at high speeds, riding on wet or slippery surfaces, and encountering uneven or loose terrain can reduce the available traction, causing the tire to skid or slip.

Bikers must mitigate these risks by employing proper braking techniques, controlled cornering, adjusting speed in challenging conditions, and selecting suitable tires for different road surfaces to ensure a safe and stable ride.

Reduce Efficiency

Improper use of friction can significantly reduce bike efficiency, leading to increased resistance and decreased performance. One of the reasons this situation happens is when braking drag, where excessive or frequent braking creates unnecessary friction between the brake pads and the wheel rims, which will slow the bike and waste the energy of the biker.

Using inappropriate tires can also increase the rolling resistance, reducing the bike’s efficiency. Furthermore, biking on rough road surfaces or poorly maintained roads also improves the friction between tires and the road, affecting the bike’s speed and efficiency.

Bikers should adopt practices that will minimize unnecessary friction to optimize bike efficiency. Regular maintenance, appropriate tire selection, optimal tire pressure, high-quality lubricants, and controlled braking techniques are essential steps to enhance efficiency, conserve energy, and enjoy a smoother, more efficient ride.

Accelerate Wear and Tear

Improper use of friction can lead to significant wear and tear on a bike’s components. Excessive braking force or misaligned brakes can cause faster wear of brake pads and damage to disc rotors or wheel rims.

Riding with underinflated tires or on rough surfaces accelerates tire wear, while poorly lubricated chains and drivetrains experience increased friction which can lead to early deterioration of the bike. Additionally, friction can impact bearings, causing premature wear and potential damage.

To minimize wear and tear, proper maintenance and regular inspections are essential. Make sure that the brakes are aligned, and tire pressure is correct to extend the lifespan of the brake pads and the tires.

Heat Generation

Prolonged and intense friction can generate heat at contact points, leading to tire blowouts or failure in extreme cases. Improper friction use can unnecessarily generate heat when excessive force or rubbing occurs between two surfaces.

Aggressive braking or extended braking periods caused excessive friction between brake pads and wheel rims or disc rotors, resulting in increased temperatures in the braking system. In addition, inadequate lubrication in areas like the chain and bearings can create friction and heat as parts rub against each other.

How is Friction Helpful When Riding a Bike

If appropriately used, friction plays a crucial and beneficial role when riding a bike, as it helps ensure a safe and efficient riding experience. Here are some ways that friction can help when riding a bike.

Traction and Stability

Friction between the tires and the road surface provides the necessary traction that allows the bike to maintain stability and prevents it from slipping or skidding during regular riding or cornering.

  • Forward Grip: Friction is responsible for the tire’s grip on the road, allowing the bike to move forward when the cyclist pedals. This transfer of pedaling energy to the ground is crucial for propelling the bike.
  • Braking: Friction is essential for the braking system of the bike to function effectively. When the cyclist applies the brake, friction between the brake pads and the wheel rims or disc rotors slows down, eventually stopping the bike.
  • Cornering Control: Friction allows the bike to maintain its path through turns and bends, giving the rider control during cornering maneuvers.
  • Safety: Friction helps the tire grip the road surface, especially driving in adverse weather conditions or on slippery surfaces, reducing the risks of accidents and improving the overall safety of the biker when on the road.
  • Controlled Deceleration: Friction can also help when a biker is decelerating. It enables controlled deceleration to allow the biker to reduce speed when approaching obstacles or navigating crowded areas gradually.


Friction is essential in biking, but it can also harm the bikers if not used properly. This article shows how friction is harmful when riding a bike and how to minimize or mitigate the effect of not properly using it.

On the other hand, if used properly, friction provides many benefits to bikers when on the road. It empowers cyclists to maneuver their bikes effectively and safely, making friction a fundamental and valuable aspect of the riding experience.
