Question

Why cycle is able to ride on two wheels?

Answer 1

Balance... if we didn’t have balance then cycle will not be able to ride on 2 wheels

Answer 2

Answer:

In a nutshell, once the wheels line up a certain way, they want to stay lined up like that. ... A non-moving bike has wheels that aren't spinning and zero angular momentum, which makes it very easy for external torque to change the wheels' direction, making the bike harder to balance.
