Four-By is one of the Biker Mice's allies in the original series. A decent Afro-American who assisted the guys in stopping Limburger's scheme to destroy the school, but was framed afterwards and forced to evacuate into the Pits. His name was eventually cleared with the Mice's help and Charley's video and decides to remain in the Pits as its self-enforcer against the Pit Boss. He drives a big and really durable monster truck he calls the Mighty Mo.
