Meet Nabiis
Performance Has No Minimum Height
Most of us grew up thinking that learning to ride was a battle. We remember the "white-knuckle" moments—squeezing brakes that were too stiff, wrestling with handlebars made for someone twice our size, and fighting a bike that felt more like a lead weight than a vehicle. We accepted it as a rite of passage.
But as I grew up and became a hardcore cyclist, I realized:
It wasn't supposed to be that way !
Real riding happens when the bike simply “disappears”，you pedal and it goes; you lean and it follows. But while adult cycling has seen a revolution in engineering, kids' bikes are still being treated like toys.
We build Nabiis from the ground up, creating calculated, age-specific solutions tailored for the 4-to-17-year-old demographic. We don’t just shrink adult frames; we engineer bikes to match the actual biomechanics of a growing body.
Built to Grow With Them
A child’s body is constantly changing: legs grow, hands grow, strength develops, and the center of gravity shifts. Nabiis designs every bike around those changes, recalculating frame geometry, standover height, cockpit sizing, Q-factor, and every key touchpoint for each stage of growth.
Easy to Carry
Most kids' bikes aren't just hard to ride — they're hard to even get out the door. A 20-pound bike doesn't fit in a 4-year-old's arms, so it becomes one more thing a parent has to lift, load, and haul up the stairs.
We started from the opposite question: what if a kid could carry their own bike? Our smallest frame weighs in at 5.6kg — light enough that most kids can pick it up themselves. No more dragging it across the driveway. No more parents throwing their back out at the trailhead.
Easy to Pedal
Watch a kid learn to ride on the wrong-sized bike, and you'll see the problem immediately: knees hitting the handlebars, toes barely grazing the pedals, legs working twice as hard for half the distance.
Crank length, gear ratio, standover height — on a Nabiis, none of it is guesswork. Every measurement is matched to actual leg length and stride, stage by stage, so the first pedal stroke feels natural instead of like a stretch. The bike should get out of the way and let the ride happen.
Easy to Brake
This one matters more than any other. A kid with small hands can't generate the same grip force as an adult — so if a bike ships with full-size brake levers, a child physically can't squeeze hard enough to stop in time. That's not a minor inconvenience. That's a safety problem hiding in plain sight.
We resize lever reach to fit smaller hands and calibrate braking force so a light squeeze is all it takes. Stopping shouldn't be the hardest part of learning to ride.

What We're Really Building
None of this is really about bikes. It's about the first time a kid pedals down the driveway without looking back to see if you're still holding on — and how much sooner that moment can happen when the bike isn't fighting them the whole way.
That's the bar we build to. Not "good enough for a kid's bike." Just good enough, full stop.
