The phone will receive a very strong acceleration before being thrown off the bike. In this case, the phone is being disconnected from the bike while receiving a small amount of force, and then hitting the ground with great force. EDIT: In a one vehicle accident where the driver lowsides onto gravel, the phone will receive a lot of forces as the bike deccelerates or tumbles, and this force will start when the phone is still attached to the bike.
