The LEGO Action Wheelers theme was part of the DUPLO brand and series of Race inspired themes. Included figures in the sets were based on the DUPLO styles. The sets themselves typically feature race cars or other supporting vehicles that came with a screwdriver or other tools where the child can take apart some pieces of the vehicles and re-assemble or replace parts. The Dozer set featured a remote control. The Action Wheelers theme ran in two waves with a totla of nine sets from 2000 and ended in 2001 when the Race theme was discontinued.
2000 LEGO Sets
2000 was a year of transition and innovation for LEGO. The company introduced RoboRiders, Knights’ Kingdom, Life on Mars, Studios, and a Soccer/Football theme while retiring veteran designer Jens Nygaard Knudsen, creator of the minifigure. Star Wars launched its first Ultimate Collector Series sets—the X-wing Fighter (7191) and TIE Interceptor (7181)—establishing LEGO’s adult collector market. BIONICLE debuted in select regions, setting the stage for a major global launch. Recognized as 'Toy of the Century,' the LEGO brick entered the new millennium as both a cultural icon and a growing creative platform.
