    Rethinking the Heavy Bike.

    Most kids are riding "monsters." A 10kg bike for a 20kg child is the equivalent of an adult on a 40kg machine. It's heavy, it's awkward, and it hurts a developing body with poor posture. For a kid, "Light" should not be a premium feature.

    That's why we started to design Lightweight Performance children bikes！

    From Static Charts

    to Kinetic Models

    Kids don't grow at a constant rate. Their legs and arms change proportions. That's why we adjust our bike geometry (Reach and Standover) non-linearly to match these shifts from ages 4 to 17.
    At nabiis, geometry isn't a guess—it's a data science. We don't just look at height; we study how a young body actually moves. Our bikes are shaped by thousands of motion-capture data points to ensure perfect knee-joint alignment and a healthy， neutral spine position. So that we can protect their developing bodies.

    Low-Gravity Geometry:

    Solving Fear with Physics

    For beginners, fear is just the brain's reaction to a "wobble." We fixed the physics so they can focus on the fun.
    By letting kids get both feet flat on the ground at any moment, we lowered the bottom bracket (BB Drop) to keep their weight low and centered.
    The result? A bike that stays upright and corrects itself, even for a first-time riders.

    Narrow Q-Factor:

    No More "Duck-Walking"


    What is Q-Factor?     Simply put, it's the distance between the pedals.
    Anatomic Alignment: Children have narrower hips than adults. If the pedals are too wide, their legs flare out or their knees buckle inward. We custom-developed our cranks to narrow the Q-Factor by the millimeter, ensuring their legs track in a perfectly straight, natural line.
    At Nabiis, We spend hundreds of hours on "Fitting", so the bike feels like an extension of the child, not a burden. Every curve of the frame and every degree of geometry is engineered to adapt a child's natural growth. We believe the bike should adapt to the rider—not the other way around.
