A bike throw is something used by a cyclist in racing. They propel the bicycle forward when crossing the finishing line in an attempt to have an extra advantage. They do so by throwing their hands forward while leaning backward. It is something that can be critical in a near photo finish.
Bike throws occur most frequently while racing on the road, in a criterium, or on the track in close finishes. This is not an easy move and requires good timing, practice, and skill—if executed incorrectly, the rider will lose speed. It is normally performed to get a slight edge on another rider in close competition. Riders practice this to finish in front of others like professional sprinters. Although the move appears to be easy, performing a precise bike throw at high speed requires excellent upper body control and bike confidence. When executed perfectly, this move is impressive and extremely significant in a race.
