#3) we dont fall when we r in motion in a bicycle cox when we move the cycle our effective weight (or center of mass balances ezactly i the centre and no extra weight in left nor in right therfore we dont fall

we dont fall front or back becoz the front wheel and back wheel are balalced in weibh but in left or right our body weight or cycles weight dominates hence more effect is in sidewards, just imagine this case with a see saw, the side with more weight goes down first, suppose some heavy man with some 100 kgs sits in the back seat then the cycle will fall backwards if the boy i the front is lighter
