A moving bicycle comes to rest after sometime we stop pedalling it But Newton's 1st law says that a moving body should continue to move for ever unless some external force acts on it . How can we explain this case ?????????

There is an external force of friction between the tyres and the road and in the axles of the bicycle acting which stops the cycle.

According to Newton's first law, the only time the bicycle would stop, is if it is acted upon by an external force. This is the exact case that happens to make the bicycle to come to a stop. The external force in this case is the friction between the bicycle and the ground. The force of friction gradually reduces the moving force until it gets to zero and the bicycle stops moving.
