Cube Bikes: Acid Kids Series

Cube Acid Kids Series: The Ultimate Progression to Mountain Biking

The Cube Acid Kids Series isn’t your normal kids bikes, painted with bright colours. It’s a scaled-down version of Cube’s legendary adult hardtail MTBs. Engineered with Aluminium Lite frames and kid-specific geometry, the Acid series provides the perfect balance of safety, durability, and trail-ready performance.

From the first 20-inch pedals to the pre-teen 26-inch adventures, the Cube Acid series is designed to grow with your child's skills and confidence.

Why Choose the Cube Acid Kids Series?

When shopping for a youth mountain bike, weight and control are everything. Cube has mastered the art of child-sized MTBs, ensuring that smaller riders aren't struggling with a bike that’s too heavy or clunky to handle.

• Lightweight Aluminium Lite Frames: Heat-treated 6061 aluminium makes these bikes easy to climb with and even easier to maneuver.

• Kid-Specific Components: Shorter reach brake levers, smaller grips, and cranks designed for narrower hips mean a more ergonomic and safer ride.

• Low Standover Height: Gives young riders the confidence to stop and start safely, reducing the "topple factor" on uneven terrain.

  • Replaceable Derailleur Hangers: Because we know kids (and bikes) take the occasional tumble, this feature saves you from expensive frame repairs.

    Exploring the Range: From First Trails to Full Sends

    Cube Acid 200 – The 20" Trail Starter

    Designed for riders transitioning from balance bikes or single-speeds, the Cube Acid 200 features a simple 7-speed Shimano drivetrain. It’s light enough for little legs to power uphill, while the V-brakes are calibrated specifically for smaller hands to provide maximum stopping power with minimum effort.

    Cube Acid 240 – The 24" Versatile Performer

    As kids get taller and bolder, the Cube Acid 240 steps up the game. Available in multiple configurations—including disc brake options and front suspension models—this bike is built for "real" trails. It bridges the gap between backyard play and weekend trail center loops.

    Cube Acid 260 – The 26" Junior Hardtail

    For the pre-teen who is outgrowing their youth bike but isn't quite ready for a full-sized adult frame, the Cube Acid 260 is the answer. It features the same geometry as the adult Acid series but optimized for smaller proportions, making it a high-performance machine for budding XC racers.
