The UCI B World Championships were the world championship for Level B bicycle road racing and bicycle time trials organized by the Union Cycliste Internationale (UCI) for nations with developing competitive cycling.
The UCI B World Championships included events for both men and women in road cycling and track cycling.
The first “B” World Championships were held in late 1997 in Ipoh, Malaysia.
The event also served as a means of qualification for the 2008 Olympic Games.
Both the road race and individual time trial events are competed by riders organized by national cycling teams as opposed to commercially sponsored or trade teams, which is the standard in professional cycling.
