Each 1:18 scale Bumble V features a front and rear suspension with rubber tires and can accelerate up to 5.6-mph on various courses across multiple terrains. Working rear taillights and front headlights ensure visibility even in dark spaces. The duo can race nonstop for up to 20-minutes on a single battery charge.
