Cube Acid Kids Series: Progression to Kids Mountain Biking

Looking for the best kids mountain bike that won't hold your child back? The Cube acid kids bike range is a scaled-down version of Cube's adult hardtail mountain bikes, not a toy bike with a bright paint job. Every model uses a lightweight aluminium frame and kid-specific geometry, so children get a bike that's easy to pedal, easy to control, their fingers reach the brakes comfortably, and tough enough for trails, parks and the school run.

With 20 inch, 24 inch and 26 inch wheel sizes, there's a Cube Acid to suit children from around 5 to 13 years old, and a clear next step as they grow.

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 Lite frames keep weight down, making hills and handling far easier.

• Kids Bikes with gears:Shimano gears across the range help young riders tackle climbs without struggling.

• Small-hand brakes:short-reach brake levers so smaller hands can stop safely, with disc brake options on selected 24" and 26" models.

• 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.
