woom GO 3 Automagic - 16 inch Lightweight Kids Bike - Powder Pink

Season:2027

Brand:Woom

Code:100878-0000-4009

The woom GO 3 AUTOMAGIC takes everything children love about the award-winning GO 3 and adds an innovative feature that makes riding even more enjoyable: an automatic two-speed hub gear. Designed specifically for young riders who are building confidence and exploring further afield, it delivers effortless gear changes without levers, cables, or controls to think about.

At the heart of the GO 3 AUTOMAGIC is woom's premium AL-6061 aluminium frame, engineered to be exceptionally lightweight while remaining durable enough for everyday adventures. The low overall weight makes the bike easier for children to accelerate, manoeuvre, and control, helping them build confidence and develop cycling skills more naturally than on heavier alternatives.

The standout AUTOMAGIC rear hub automatically shifts between two gears as speed increases, providing an easier gear for starting and climbing, then smoothly changing into a higher gear when the pace picks up. Because the shift happens automatically, young riders can focus entirely on steering, braking, and enjoying the ride rather than worrying about gear selection.

The carefully developed frame geometry creates an upright riding position that promotes stability, visibility, and comfort. A low step-through frame makes mounting and dismounting easy, while the long wheelbase and balanced handling characteristics inspire confidence on everything from quiet streets and cycle paths to family adventures further afield.

Rolling on lightweight 16" wheels with Schwalbe tyres, the GO 3 AUTOMAGIC delivers a smooth and comfortable ride across a variety of surfaces. The tyres offer excellent grip and shock absorption, helping young cyclists maintain control while exploring with confidence.

As with every woom bike, the contact points have been designed specifically around children's proportions. The ergonomic saddle, narrow handlebars, child-sized grips, and easy-to-reach brake levers ensure young riders remain comfortable and in control throughout every journey. The colour-coded rear brake lever helps reinforce safe braking habits and improves confidence as riding skills progress.

By removing the complexity of manual gear shifting, the GO 3 AUTOMAGIC creates a smoother riding experience and helps children develop confidence more quickly. It's the perfect choice for young cyclists who are ready to ride further, faster, and with greater independence.

Available in Woom Red, Metallic Turquoise, Metallic Blue, Hot Pink, Vibrant Yellow, Powder Pink, and Neon Lime, the GO 3 AUTOMAGIC combines innovative technology with vibrant styling to create a bike that's as fun as it is capable.

Professional Opinion

The woom GO 3 AUTOMAGIC is one of the most innovative children's bikes available because it solves a common problem many young riders face: understanding when and how to shift gears. The automatic two-speed system removes that learning barrier entirely, allowing children to enjoy the benefits of multiple gears without adding complexity.

What makes the bike particularly impressive is that the automatic hub works seamlessly in the background. Young riders simply pedal as normal, enjoying easier starts and climbs alongside more efficient cruising at higher speeds. This creates a more enjoyable riding experience while allowing children to focus on developing core cycling skills.

Combined with woom's renowned lightweight construction and excellent child-specific design, the GO 3 AUTOMAGIC is a fantastic option for children who have mastered the basics and are beginning to ride longer distances. It's a premium bike that genuinely makes cycling easier, more comfortable, and more fun for young riders.
