Orbea Kimu 20 H20 Cobalt Blue

The Orbea Kimu 20 H20 Cobalt Blue is a high-quality 20-inch kids’ mountain bike for young riders ready to move on to easy trails, longer bike rides and versatile everyday riding. Its lightweight aluminum frame, rigid Orbea Kimu fork, hydraulic disc brakes and 1x8-speed drivetrain make it safe, easy to handle and ideal for active kids.

The Kimu 20 H20 is designed around children’s proportions—it’s not just a scaled-down adult bike. Its low standover height, child-friendly brake levers, narrower grips, short 115 mm cranks and controlled riding position make it easier to handle. The 20 x 2.20” Kenda Booster tires offer good traction on gravel roads, forest trails and around town, while the hydraulic Clarks M2 disc brakes provide reliable stopping power, even in wet conditions.

The Cobalt Blue color gives the bike a fresh, sporty look. The Kimu 20 H20 is especially well suited to a child looking for a lightweight, durable bike genuinely designed for off-road riding and their first faster-paced cycling adventures.

Orbea Kimu 20 H20 - specifications and features

The Orbea Kimu 20 H20 is built to give young riders confidence, enjoyment and great control. The aluminum frame keeps the bike lightweight and durable, while the rigid aluminum fork provides precise steering and reduces unnecessary weight compared with budget suspension fork models.

The Microshift 1x8-speed drivetrain is straightforward for kids to use: a single chainring and a wide-range 11–38T cassette provide enough gears for flat ground and hillier terrain, without the complexity of a front derailleur. The 28-tooth chainring and short 115 mm cranks are sized for young riders, making pedaling feel natural while maintaining good control of the bike.

Details on the Kimu 20 H20 are designed with growing riders in mind. The adjustable “Growing Stem” can be extended from 40 mm to 55 mm using a spacer, helping the bike fit for longer as your child grows. The Low Stack seatpost allows for a lower saddle height and makes it easier to get on the bike. Reflector-equipped pedals and a front fender are included for added practicality on everyday rides and outings.
