Kids Bike Woom Original 4 20" Red

The Woom Original 4 children's bike stands out because it is built entirely from components specially designed to meet the needs of young riders. At its core is a lightweight aluminum frame with geometry that ensures a naturally upright riding position and provides safe, confident handling. A color-coded rear brake helps children distinguish the controls and quickly learn riding skills. A steering limiter, chain guard, and lightweight Kenda tires add to the bike’s safety and comfort.

Innovative Frame
The aluminum alloy frame features a simple shape with sophisticated geometry tailored for young cyclists. It's ultra-lightweight, durable, and offers a stable, easy, and safe ride.

Easy Braking
Safety is always the top priority. With brakes specifically designed for small hands, children can easily control their speed and stop reliably.

Vario Stem
The adjustable Vario stem allows for easy changes to handlebar height and reach, so the bike can grow with your child.

Narrow Pedal Q-Factor
For natural and comfortable pedaling, kids need not only shorter crank arms but also a narrower distance between the pedals. Woom bikes feature original narrow bottom brackets for optimal ergonomics.

Intuitive Shifting
The easy-to-use microSHIFT twist shifter lets kids shift through seven gears with minimal effort and maximum control.

Quick-Release Levers
Quick-release levers make life easier: they allow for fast and tool-free removal of the front and rear wheels — helpful for transport or fixing a flat tire.

Ergonomically Designed Saddle
The saddle is one of the key contact points between the child and the bike. Its shape has a major impact on riding comfort, which is why Woom saddles are specifically designed for children.

Quick-Release Seat Clamp
This seat clamp makes it easy to adjust the saddle height quickly and without tools — even kids can do it themselves. So hop on and ride!

7-Speed Drivetrain

Precise and reliable shifting helps kids climb hills and ride longer distances more easily. With a 7-speed 11–28T cassette and a 28T front chainring, every ride becomes a fun adventure.
