Orbea Kimu 20 H20 Kid MTB Acid Gum 2027

The Orbea Kimu 20 H20 is the ideal ally for young riders ready to explore new horizons with more freedom on two wheels.

It all starts with a spark of passion. The Kimu 20 H20 has been designed for children aged 5 to 8 who are looking for bigger adventures. With its 20-inch wheels and high-performance design, this bike makes every outing easier and more fun. Thanks to the Big Wheel Concept, obstacles become smaller, encouraging the child to tackle more technical trails with stability and momentum comparable to adult bikes.

A bike that grows with the rider thanks to tailor-made ergonomics. The major innovation of this model lies in its exclusive adjustable stem: thanks to an easy-to-install spacer, it can be adjusted from 40 to 55 mm, extending the bike's lifespan. With its advanced aluminum frame featuring polished welds and a low seatpost for easy mounting (standover), the Kimu 20 H20 transforms every challenge into a gain in character and confidence.
