2026 Cube Cube Reaction 240 Pro Kids Bike In Black And Blue And Red
Light, fast, tough, fun – just like the little mountain biker in your life. The Reaction 240 Pro has everything they need to explore their limits, and nothing they don't. The full carbon fork with thru axle is light and comfortable. Wide-ranging Shimano Cues 1x10 gears have the range to tackle any trail. Powerful disc brakes with Schwalbe tyres – just like on our full-size mountain bikes – are extra reassuring. And contact points designed for junior proportions ensure that your young rider is comfortable and in full control, all the time.
