The Roboriders were released in 2000 and overlapped the Slizers. Like the Slizers, they departed from the usual Technic subject matter and parts. In this case, rather than anthropomorphic robots we have robotic motorcycles. Four of them were micro sized models with almost no features at all, six were small sized play sets with a single feature, and the final model was substantially larger. The common feature of the sets used a specialized flexible housing to throw the wheel discs. Sadly, this feature didn't really work at all which helps explain why this series only lasted a single year.
Each model was a different color and the color matched a themed name and personality. Each also had a unique printed robotic "face", although the micro models reused these parts from the larger models. The discs were also unique to each model, and extra discs were available as a supplemental set. These models are a good source of cheap connector parts in rare colors.
The smallest 4 set were released under multiple numbers since they were also available in Japan packaged with Kabaya candy.
By 2001 this type of set would disappear from Technic and become Bionicle.
