Answer
assertion is true but reason is false
Explanation
Assertion (A) is true because once pedalling stops, no external force is applied to keep the bicycle moving then frictional forces cause the bicycle to gradually slow down.
Reason (R) is false because friction always acts opposite to the direction of motion, resisting it.
