The woom OFF 4 is built for young adventurers who want to leave the tarmac behind and explore the world off-road. Combining premium materials, child-specific geometry, and high-quality mountain bike components, it delivers an exceptional riding experience that helps young riders tackle trails with confidence and develop real off-road skills.
At the heart of the OFF 4 is an ultra-lightweight aluminium frame engineered specifically around the proportions and riding dynamics of children. The carefully designed geometry provides a balanced and stable riding position, helping riders feel confident whether they're climbing steep hills, navigating winding singletrack, or enjoying family rides through local forests.
One of the standout features of the OFF 4 is its lightweight rigid carbon fork. By replacing heavier suspension forks with a premium carbon design, woom has created a bike that remains light, responsive, and easy to manoeuvre. The carbon fork helps absorb trail vibrations while improving steering precision, allowing young riders to maintain control across rough terrain without the additional weight and maintenance associated with suspension systems.
The OFF 4 is equipped with a reliable SRAM 1x9 drivetrain, providing a wide range of gears without the complexity of a front derailleur. This simple yet highly effective setup makes shifting easier for younger riders, allowing them to focus on the trail ahead while still having the gearing needed to tackle climbs, descents, and rolling terrain with confidence.
Stopping power comes from Promax hydraulic disc brakes, a premium feature that offers exceptional control in all weather conditions. Requiring less hand strength than traditional rim brakes or mechanical disc systems, hydraulic brakes are ideally suited to younger riders, delivering predictable performance and increased confidence on technical descents and loose surfaces.
Rolling on lightweight 20" wheels fitted with off-road-ready tyres, the OFF 4 provides excellent grip, stability, and efficiency on a variety of surfaces. Whether riding through woodland trails, gravel tracks, bridleways, or local trail centres, the bike offers predictable handling and plenty of traction when conditions become challenging.
As with every woom bike, the details matter. Child-specific grips, an ergonomic saddle, and carefully proportioned handlebars ensure maximum comfort and control, while the lightweight construction encourages young riders to ride further and tackle obstacles they may have previously avoided.
The result is a genuine mountain bike for children that delivers many of the same performance benefits found on premium adult trail bikes, but in a package perfectly tailored to younger riders.
