Minimal weight. Maximum fun.

The next-generation woom OFF 4 is an ultralight, super capable mountain bike for kids aged six and up, designed to introduce your child to a world of off-road adventure and help them take their bike skills up a gear. The ergonomic design, child-specific all-terrain geometry, premium components and tubeless-ready setup provide total control and added safety.

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.

Durable carbon fork

Superlight and super stylish – the carbon fork balances maximum stability with minimum weight. Multidirectional carbon fibres ensure plenty of torsional strength when steering and braking. This design inspires confidence on even the roughest descents.

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.
