ORBEA KIMU 27 H20 Ready to Go!

Orbea Kimu 27 H20 – 27.5” junior bike for trail riding and active use

The Orbea Kimu 27 H20 is a high-quality 27.5-inch junior bike for the young rider ready to move from a kids' bike toward true mountain biking. The lightweight Orbea Kimu 27.5 aluminum frame, RockShox Judy Silver TK air suspension fork, Shimano Cues 1x10 drivetrain and Shimano MT410 hydraulic disc brakes make it a capable, safe and versatile choice for trails, gravel roads, forest rides and an active everyday life.

The 27.5” wheel size adds rolling speed, stability and off-road capability compared with smaller junior bikes. Kenda Booster 2.40” tires provide good grip and comfort on varied surfaces, and the 110 mm RockShox suspension fork improves control over roots, gravel and uneven trails. The result is a bike that feels like a real mountain bike to a young rider, yet is sized and specified for junior use.

The growth-adjustable stem, 155 mm crank length, 680 mm handlebar and a riding position designed for children and teens make the Kimu 27 H20 a long-lasting choice for a developing rider. It is an excellent bike for a young rider who wants to ride further, faster and on more technical routes than on a traditional kids' bike.

Orbea Kimu 27 H20 – a thoroughbred mountain bike for the young rider

The Orbea Kimu 27 H20 is designed for junior riders who need a light yet genuinely trail-capable bike for developing their riding skills. 27.5” wheels, low and manageable frame geometry and a quality component selection make it a good option for a young rider who rides gravel roads, forest paths and trail-style routes as well as to school and in everyday use.

The Orbea Kimu 27.5 frame is built from aluminum, making the whole durable, practical and suited to junior use. The geometry is clearly mountain bike-like: a slack 66.5-degree head angle, 420 mm chainstays and a 1088 mm wheelbase bring stability to faster riding and more technical surfaces. This helps a young rider learn riding lines, weight shifting and control with more confidence.

The RockShox Judy Silver TK suspension fork with 110 mm of travel and a 15x110 Boost axle clearly raises the Kimu 27 H20 above a standard junior bike. The air suspension fork dampens bumps, improves front tire grip and provides more control when the route gets rocky, rooty or otherwise more technical. This also makes the bike suitable for a rider who wants to progress in real off-road riding.

The drivetrain is a Shimano Cues 1x10 system. The Shimano Cues U6000 GS Shadow rear derailleur, Shimano Cues SL-U6050 S-Reach shifter and 11–48T cassette offer a wide gear range for hills, transfers and varied terrain. The simple 1x design reduces the need for adjustment and makes shifting clear for a young rider.

Shimano MT410 hydraulic disc brakes provide confident braking power and a good feel. A hydraulic disc brake is an important feature on a young rider's mountain bike, because it needs less finger strength and works reliably on wet surfaces, loose gravel and descents. Good modulation adds control and helps develop riding technique more safely.

The Kenda Booster 2.40” tires and WH 2.1 aluminum wheels form a durable and versatile wheelset. The wide tire improves grip and comfort on trails but still rolls well on harder surfaces. Pedals with reflectors and Orbea's growth-adjustable stem make the bike both a good-looking and practical choice for a young, active rider.
