The Rocbird Junior is more than just a “kids' bike”. It’s a top-of-the-line, fully equipped dream build that gives young riders the confidence to progress and the tools to chase their MTB passion. It is a tailor-made enduro machine for the young shredders, rolling on a 27.5"/26" mini-mullet setup. With 160 mm of rear travel and geometry inspired by our full-size Rocbird frames, it’s the perfect bike for kids who want to improve their riding skills - and for parents who might need to work harder to keep up at the bike park.
The Manitou Mezzer Pro fork with 160 mm travel provides perfect precision and stiffness, while the RockShox Deluxe Select+ shock keeps the rear end supple and supportive over rough terrain.
The drivetrain is built around the reliable Shimano CUES 1x10 system with an 11-48T cassette, offering plenty of range for climbing and descending. Stopping power comes from Hayes Dominion A2 brakes with short levers, perfectly scaled for smaller hands without compromising performance.
Strong Patrol welded rims, Kenda Hellkat 120 TPI All-Mountain tires, a Dartmoor Shorty stem, and an X-Fusion Manic LC dropper post complete a setup that’s light, tough, and ready for serious trail riding.
With its dialed geometry, top-tier components, and unbeatable value, the Rocbird Junior is a true enduro machine for the next generation of riders - now available in brand-new colorways: the bold Solar Eclipse fade combining yellow and black, and the sleek Cool Grey/Blue - both finished with fresh, youthful graphics.
Because at Dartmoor-Bikes, even the junior bikes are built to fly.

The modern progressive geometry of the Rocbird allows for a bottomless feel at the end of the curve, accommodating both, spring and air shocks. Each type of shock has its advantages, so the choice depends on personal preference and how the rider prefers their suspension. We aim to accommodate Rider Your Way in all aspects.
The Rocbirds' high leverage ratio at the start of travel helps overcome friction, making the initial part of the ride smooth. Towards the end of the stroke, increased progression provides resistance against bottoming out, ensuring the bike can handle any challenges you encounter.
Are you torn between riding in bike parks or tackling challenging enduro trails with roots, rocks, and mud? The Rocbird can help you with its replaceable shock mount, which allows you to use two different sizes of shocks. This means you can adjust the frame travel to 160mm or 140mm, accommodating various riding styles and preferences.
Rocbird frames are fully compatible with SRAM Universal Derailleur Hanger (UDH) and Eagle Transmission drivetrains.
Our custom bicycle frame protectors are made of thick thermoplastic elastomer material, providing excellent protection against scratches, dents, and impacts. The ribbed pattern design adds durability, and these protectors are specifically tailored to fit Rocbird's frames, offering maximum protection without sacrificing aesthetics.
All Rocbird frames use screw-in bottom bracket type, as we believe it's the best type of BB for MTB frames, because of their durability and easier maintenance. Also, Rocbird frames, thanks to a special cut on the BB shell, can use a dedicated ISCG05 mount, which can be purchased separately. This allows riders to add a chain guide and bash guard, leaving the option open for personal preference.
Yes, we know that mechanics hate it, but we all want clean, nice-looking bikes. This feature makes all frames at least 10% more stylish.
All bearings in our full suspension frames feature extra dedicated custom sealing for enhanced protection against dust, dirt, and moisture. Red Mobil grease provides effective lubrication over extended periods, ensuring minimal friction and optimal performance. MAX-type bearings provide over 30% more load capacity than caged bearings.
