Built to Grow. Built to Ride.

The 2027 Orbea KIMU 27 H10 is a purpose-built kids mountain bike designed to give young riders the confidence, control, and capability to tackle trails, school runs, and everything in between. Developed on Orbea's dedicated KIMU platform — engineered specifically for growing riders, not scaled-down adults — this bike delivers a genuinely premium off-road experience in a 27-inch wheel format.

In the vibrant Aloha Green colourway, this is a bike that turns heads on the trail and in the bike park.

Why the KIMU 27 H10?

• KIMU-specific geometry — shorter reach, lower standover, and a more upright riding position tailored to a child's proportions, giving young riders immediate confidence on the bike
• 27-inch wheels — the ideal wheel size for riders transitioning from junior to full-trail riding, offering better rollover capability and stability on varied terrain
• Lightweight aluminium frame — the KIMU platform uses a dedicated kids' alloy frame that keeps weight low without compromising stiffness or durability
• Shimano Altus H10 drivetrain — reliable, easy-to-use gearing that young riders can operate confidently, with smooth, predictable shifts across a wide gear range
• Mechanical disc brakes — consistent stopping power in all weather conditions, with levers sized for smaller hands to ensure safe, controlled braking
• Suspension fork — front suspension absorbs trail chatter and drops, letting kids ride longer and harder with less fatigue
• Aloha Green colourway — a fresh, eye-catching finish that stands out on every ride

The KIMU Platform: Designed for Young Riders

Orbea's KIMU range is built from the ground up for kids aged roughly 8–14, with geometry data gathered from real young riders. Every tube angle, stack height, and component spec is chosen to match how children actually ride — not how adults do. The result is a bike that feels natural from the first pedal stroke, builds skills faster, and grows with your child through the critical years of cycling development.
