More Bike. More Trail. More Fun.

The 2027 Orbea KIMU 27 H20 is the higher-spec 27-inch kids mountain bike for young riders who are ready to take their riding to the next level. Built on Orbea's dedicated KIMU platform — engineered from the ground up for growing riders, not scaled-down adult bikes — the H20 steps up the component spec to match the ambition of riders who want more from every trail.

In the vibrant Aloha Green colourway, this is a bike that performs as good as it looks.

Why the KIMU 27 H20?

• Upgraded H20 specification — a step up from the H10, the H20 build brings higher-grade components for improved performance, reliability, and ride quality on more demanding terrain
• KIMU-specific geometry — shorter reach, lower standover, and a proportionate cockpit designed around how children actually sit and ride, delivering immediate confidence on the bike
• 27-inch wheels — the ideal size for riders aged roughly 10–14, offering superior rollover capability, stability, and speed on trails and mixed terrain
• Lightweight aluminium frame — the KIMU platform's dedicated kids' alloy frame keeps weight low without sacrificing stiffness or durability
• Shimano drivetrain — smooth, reliable gearing with child-sized shifters for confident, precise gear changes on climbs and descents
• Hydraulic or mechanical disc brakes — powerful, consistent stopping in all weather conditions with levers sized for smaller hands
• Suspension fork — front suspension soaks up trail chatter, roots, and drops so young riders stay in control and comfortable on longer rides
• Aloha Green colourway — a fresh, premium finish that stands out on the trail

The KIMU Platform: Built for Young Riders Who Mean Business

Orbea's KIMU range is developed from the ground up using geometry data gathered from real young riders. Every tube angle, stack height, and component spec is chosen to match how children actually ride. The H20 models are for riders who've found their confidence and are ready to push further — more technical trails, longer rides, bigger ambitions.
