2026 Cube Acid 240 Hybrid Rookie SLX 400X Youth Electric Mountain Bike In Reed Green & Matrix

There's nothing quite like a young rider's enthusiasm, but sometimes they need a little extra boost. With its lightweight Bosch SX drive, 400Wh battery, dropper post, air suspension fork and 2.35in tyres, the Acid 240 Hybrid Rookie SLX is everything they need to hit the trails with confidence and come out on top.

Details matter when you're designing a bike for young riders. The Acid 240 Hybrid Rookie SLX's Magura MT Thirty hydraulic disc brakes, for example, aren't just powerful. They also feature excellent lever adjustment, so they can be set up perfectly for small hands. Combined with the 19mm-diameter handlebar and the easily adjustable air suspension fork, it's the kind of thing that can make all the difference.

A remote dropper post will help give their confidence a boost, and big volume 2.35in Schwalbe Hans Dampf tyres have the grip they'll need to build their riding skills. And, with pedal assistance up to 20km/h from Bosch's lightweight SX drive and 400Wh battery – delivered via Shimano's smooth 1x11 Cues gears – there's plenty of extra shove on tap for fun family rides.

From its Advanced Internal Cable Routing to its Boost rear axle and UDH gear hanger, the Acid 240 Hybrid Rookie's frame is bursting with exactly the same kind of attention to detail as our adult mountain bikes. The lightweight Bosch SX drive and fixed 400Wh battery sit snugly in the frame, providing up to 55Nm of pedal assistance to a maximum speed of 20km/h, plus full compatibility with the optional 250Wh PowerMore range extender.

It's even dropper seatpost ready and SIC 2.0 compatible, for easy fitting of a luggage carrier. And, with the included kickstand, your youngster will never struggle for somewhere to park it.
