Because the portion of tire touching the ground is not moving relative to the ground.
Some examples of rolling friction include a car's tires rolling on the road, a ball rolling on the ground, and a person riding a bike. Rolling friction occurs when an object rolls over a surface and is caused by the deformation and adhesion of the surfaces in contact.
Yes, static friction occurs between the bike's tires and the road surface when riding. This friction helps the bike maintain traction and grip, allowing it to move forward efficiently and providing stability during turns and braking.
Say you are driving a car or riding a motorcycle and you just remove you foot or hand from the accelerator. What will happen? After some time depending on your velocity, the vehicle will stop. Why? Consider your entire vehicle an ideal system meaning that no part provides any sort of friction. Now consider road, road is rough and will definitely provide friction. Since your vehicle's tires are rolling against the road, the road will provide friction in the direction opposite to that of your vehicle's motion. In real situations, both tire and road will contribute to the rolling friction.
A child applying the brakes on his bike is an example of sliding friction, as the brake pads create friction against the bike's wheels to slow it down.
Rolling friction acts on a rolling wheel. It is the resistance that occurs between the wheel and the surface it is rolling on. Rolling friction is generally lower than static or kinetic friction.

Rolling down a slope.
Sliding Friction
Yes, static friction occurs between the bike's tires and the road surface when riding. This friction helps the bike maintain traction and grip, allowing it to move forward efficiently and providing stability during turns and braking.
You would experience fluid friction and rolling friction, and since you are not likely to be completely submerged, air resistance.
The forces acting on the bike is gravity, air resistance and friction.
applied, normal, and friction
Friction - several different kinds - and inertia. If riding uphill, also gravity.

The best men's bike for casual riding is typically a hybrid bike, which combines features of road and mountain bikes for versatility and comfort on various terrains. Look for a bike with a comfortable seat, upright riding position, and smooth-rolling tires for a pleasant riding experience. Popular brands to consider include Trek, Giant, and Specialized.
