Drag is reduced to cut down on how much energy is needed to get a car from point a to point b and to make it go faster and accelerate faster. To cut down on drag, you make the car more aero dynamic, to cut back on how much wind is slowing your car down.
First look at the rider's clothes, they should be tight fitting and slick. Then look at the position, the rider should display as little frontal area as possible.
Then look at the bike, which should also be as streamlined as possible. Low spoke count wheels, high profile rims etc.

How can drag be reduced in practice?
Air drag can be reduced by improving riding posture and the use of tight fitting slick clothes.. Mechanical drag can be reduced by the use of high quality bearings.
Induced drag in airplane is reduced by?
winglet
What is Advantage of swept back wing?
reduced drag
How is drag reduced?
Change the shape / Reduce the size / smooth the surface texture.
What is the main purpose of a parachute?
Drag. It reduced the fall rate to a survivable speed.
How can drag be reduced when flying a plane?
Drag can be reduced when flying a plane by minimizing air resistance. This can be achieved by reducing the aircraft's speed, using streamlined designs, retracting landing gear, and keeping the surfaces clean. Additionally, flying at higher altitudes where air density is lower can also help reduce drag.
What about wingtip using in aircraft?
Reduced certain type of drag (air resistance) and thus improves fuel efficiency and range.
How do you control drag from increasing on helicopter?
Drag cannot be eliminated because drag always acts parallel to the relative wind. We can control by purchasing or using the right airfoil on the aircraft. An airfoil with smooth surface produces more lift than one with a rough surface. A rough surface creates turbulence, which reduced lft and increases drag.
How can parasite drag of an airplane be reduced?
It can be reduce by streamline as many of the parts as possible, by using fairing , surface of aeroplane cleaned and polished.
How is drag eliminated on a helicopter?
Drag on a helicopter can be reduced by streamlining the body and rotor blades, ensuring smooth airflow over the surfaces. Another way is to use a more powerful engine to generate more lift with less drag. Additionally, adjusting the pitch of the rotor blades to the most efficient angle helps in reducing drag.
How are airplanes designed to reduce drag?
Airplanes are designed to reduce drag by incorporating streamlined shapes and smooth surfaces to minimize air resistance. Winglets at the end of wings help reduce the formation of vortexes that create drag. Advanced materials and coatings are also used to reduce skin friction drag on the aircraft's surface.
What is one way to change drag on a airplane?
Drag can be reduced by flying at higher altitudes, where the air is thinner. Drag increases with speed as well, and some friction is unavoidable when generating lift. To reduce drag in design, the exterior should be as smooth as possible, and external protrusions should be faired into the body, creating the smallest possible cross section as seen from the nose (direction of motion).
