We believe that learning to ride should bring joy, not fatigue and frustration. On a kids’ bike, every gram matters. If the bike is too heavy, it’s harder for a child to keep balance, steer, or even lift it off the ground or move it out of the way.

Why is the weight of the bike the most important thing?

Confidence and safety in every ride 

Easier to control, fewer falls, safer rides.

Fast learning, zero stress 

More joy, quicker progress.

Healthy growth 

Less strain on back, joints, and posture.

Longer rides, no fatigue 

More fun for kids, less hassle for parents.

Coaster brakes work by pedaling backward to stop the bike. We decided to eliminate them because this mechanism is outdated and inconvenient.

Why doesn’t our bike have coaster brakes?

Easy Start

Pedals always in the right position.

Stable Balance

No backward pedaling to disrupt movement.

Accurate Braking

Quick, safe stops anytime.

Training wheels hold kids back from learning the most important skill — balance. Biky Air teaches it from the very first ride, making cycling feel natural and intuitive. 

Why else is the absence of training wheels important?

Faster Learning

Kids quickly gain balance and feel confident.

Fewer Mistakes

Smooth starts, easy braking, better control.

Comfort that supports growth 

Natural posture, easy motion, confident riding.

It means that the frame and every component are made specifically for children.

And here’s why:

Frame

The frame: the foundation of comfort and safety. Every detail is meticulously designed to make pedaling effortless and the riding position feel natural—so your child can enjoy every ride with ease. 

Aluminum Frame

Durable 6061-T6 alloy — light and reliable.

Longer Wheelbase

More stability and confidence when learning to ride.

Lower Saddle

Easy to hop on and off without losing balance.

Lower Bottom Bracket

Better balance and safer handling.

Integrated Cable

Hidden cables for safety and durability.

Narrow Design

A smarter fit for little riders.

Kids aren’t just smaller adults —that’s why the Biky Air is designed for their unique anatomy, not just scaled down from a grown-up bike. We’ve optimized the Q-factor —the distance between the pedals—for a more natural, comfortable ride. Why does it matter? 

Narrow Q-factor

Lightweight 6061-T6 aluminum frame with perfect weight-to-stiffness balance for comfort and control.

Narrow BB 47 mm

Internal cable routing prevents snags, adds safety, and extends cable life.

Narrow Hubs 85 mm

Wider wheelbase improves stability and helps kids balance with confidence.

Components

Grips

Standard grips are too big for little hands. Ours are perfectly sized for a secure, comfortable hold—giving kids more control, less fatigue, and a ride that feels effortless. 

Chain Guard

Fully enclosed chain – Keeps legs and clothes safe from grease, snags, and sudden stops. No more tangled laces or messy rides. 

Brakes

Brakes made for little hands. A light pull delivers instant stopping power—no strain, no struggle, just total control. 

Wheels

Sealed bearings for effortless, silky-smooth rolling. Faster starts, less fatigue, and more fun with every push. 

Air-filled tires with reflective stripes — cushion bumps and keep your child visible after dark. 

TPU inner tubes — tough, puncture-resistant, and built to last. No sudden stops, just pure riding joy. 

Speed

Single speed

Single-speed simplicity – No gears to fumble with—just pure, effortless riding. Less maintenance, more fun. 

Gain Ratio 

Perfect balance. Effortless rides. The right ratio of wheels, frame, and pedals reduces strain and keeps every ride smooth, easy, and fun. 

Loud Freewheel 

That distinct crackling sound when your child isn’t pedaling can be heard from far away, letting everyone around know — a little cyclist is nearby!
