Why are you more stable when riding a bicycle at a faster speed?
 A You have more mass B The wheels have angular momentum C It’s not easier to ride at a faster speed D The bike has more momentum
Explanation:

Detailed explanation-1: -The bicycle has more angular momentum which means it is more stable when traveling at a faster speed. 2. It is not easier to ride a bicycle at a faster speed because the bike has more linear momentum. This means that the bike will continue moving in a straight line even when you are pedaling at a faster pace.

Detailed explanation-2: -A symmetric body with no torques applied with even a slight bit of internal damping (as all real object have) will eventually rotate about its principal axis with the lowest moment of inertia. The faster the spin (= higher angular momentum), the more effort it takes to alter the axis of the spin (= greater stability).

Detailed explanation-3: -The Answer: The reason for this is the conservation of the angular momentum. A bicycle has wheels that once in motion, they rotate. Each rotating wheel is generating a non zero angular momentum.

Detailed explanation-4: -What we do know about how conventional bikes stay upright on their own is this: when a moving bike starts leaning to one side, it also automatically steers towards that side a little bit. The result is that the wheels come back underneath the center of mass, keeping the bike balanced.

Detailed explanation-5: -Gyroscopic forces are not important for the stability of a bicycle-as you can see if you read on below-but they help us to control the bike when riding with no hands. More important than anything is “the trail".
