The ultralight and durable 20″ mountain bike with front suspension, 9 gears and disc brakes designed for children aged 6 years and over.

 

Welcome to the world of flow!

The next-generation woom OFF AIR 4 is an ultralight, durable hardtail mountain bike with serious all-terrain capabilities for kids aged six and up. With high-quality front suspension and powerful disc brakes, it teams maximum comfort with full control for the ultimate performance on XC trails, gravel tracks, tarmacked lanes and beyond.

 

Superlight frame

The ultralight aluminium frame has capable off-road geometry with a long wheelbase and slack head angle for improved stability and smooth, responsive handling. Extra confidence comes from the kink in the top tube, which makes it easy to dismount quickly in any situation.

Premium suspension fork

Comfort and control on the bumpiest terrain is a given thanks to the fully tunable suspension fork, which can be adjusted to the rider’s weight. With adjustable compression and rebound damping, the fork can be tuned precisely for any terrain or conditions and features a lock-out function that basically switches off the suspension when not needed – meaning full fun on the trails and a faster ride up hills or on the way home!

Ergonomic contact points

The age-appropriate MTB saddle and ergonomically profiled handlebar grips add comfort, while the hard-wearing platform pedals with metal pins provide the necessary grip for all-terrain riding.

Precise shifting

The precise and intuitive SRAM X5 drivetrain has nine gears and a wide gear range thanks to the 28-tooth chainring up front and an 11–32 cassette at the rear. The easy-to-operate trigger shifter operates smoothly and reliably to make light work for children’s thumbs.

Reliable disc brakes

Easy-to-modulate disc brakes are teamed with child-specific, reach-adjustable brake levers to provide maximum stopping power and control in every situation including steep slopes and wet conditions.

Grippy tubeless-ready MTB tyres

High-quality Schwalbe mountain bike tyres combine low rolling resistance with superior grip and proven durability. With Tubeless Easy technology and tubeless-ready rims, it’s a straightforward transition to go tubeless and benefit from added comfort and grip.

Lightweight flip-flop stem

Specially developed from forged aluminium, this stem pairs the ultimate stiffness with the lowest possible weight. Thanks to its flip-flop design, there’s the option to raise the height of the bars simply by inverting it.
