The CCM Assault 20" Bike is a serious off-road machine designed for tearing up the trails. The lightweight aluminum frame makes for a lean and strong bike. The front and rear suspension systems keep your tires firmly on the ground when the terrain is rough. This bike also features a front disc brake, making it easy to stop in all conditions. The best part is the 6-speed Shimano Revo shifting system, giving you the gears you need to get up the hills and back down again.
