Question

you find that it is easier to increase your speed on your bike if you crouch down and make your body as small as possible. How does this helps you

Answer 1

Step-by-step explanation:

Crouching down so that your body is parallel with the ground decreases the cross sectional surface area, making you more aerodynamic.

In other words, there's less area for the air to push on, so there's less air resistance.
