Description
An ultralight and durable 20″ mountain bike with a carbon fork, 9 gears and disc brakes designed for children aged 6 years and over.
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.
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.
