The Marin Bear Valley 24" Hardtail Children's Mountain Bike 2026 in Blue Green is built for young riders who are ready to explore trails, tackle adventures, and develop their mountain biking skills. Designed with the same attention to detail as Marin’s adult trail bikes, the Bear Valley combines a lightweight aluminium frame, proper MTB geometry, and kid-specific components to create a capable, confidence-inspiring bike for growing riders.
Available from The Rolling Fix, Liverpool’s independent bike shop, the Marin Bear Valley is one of the most thoughtfully designed kids mountain bikes in the range. Whether it’s woodland trails, bike parks, family rides, or everyday adventures, this 24-inch hardtail is ready to shred.
At the heart of the Bear Valley is a Series 2 lightweight aluminium MTB frame with a low standover height, giving young riders improved confidence when mounting, stopping, and riding technical sections. The frame features modern mountain bike geometry, a replaceable derailleur hanger, and disc brake compatibility, providing a strong and reliable platform that can handle years of riding.
The MicroSHIFT Acolyte 1x8 speed drivetrain delivers a wide range of gears that are simple to use and perfectly suited to young riders. The clutch-enabled rear derailleur helps keep the chain secure over rough terrain, while the short-reach shifter makes changing gears easier for smaller hands.
For control and confidence on the trails, the Bear Valley is equipped with Tektro HD-J285 kid-specific hydraulic disc brakes. Featuring short-reach alloy levers designed for smaller hands, these powerful brakes provide smooth, reliable stopping performance in all weather conditions.
The bike rolls on fast yet grippy 24 x 2.25" MTB tyres, offering excellent traction across gravel paths, trails, and uneven ground. Combined with strong double-wall aluminium rims and Marin’s own range of child-specific finishing components, the Bear Valley delivers a balanced ride that encourages young cyclists to progress.
