That day I sit behind the bicycle rider. That was my first time for sitting behind the bicycle rider.My friend was driving a motorcycle speed.I met the intersection without traffic lights. I noticed that a pickup a rush from the white at the same time I saw a truck was coming through the left. Without a motorbike I stacked in the middle.Car, motorcycle, abrasives and truck crash. This event that I dare not to ride on the back of a motorbike.
