WOOM OFF AIR 4

For kids who love to ride off the beaten path.

The WOOM OFF AIR 4 is made for young adventurers (from about age 6 / 115 cm) who have long outgrown the sidewalk. This bike feels just as at home on a forest trail as it does on a gravel road. And let’s be honest: in that new Copper color, it looks like it just rolled out of a futuristic bike park 🔥

This super-light 20-inch MTB comes equipped with an air suspension fork, powerful hydraulic disc brakes, and grippy off-road tires. Perfect for little riders with big plans. From pump tracks to hilly trails, this bike is made for action.

🔧 Built to fly (and land):

🪶 (Weight) Just 8.6 kg – lightweight aluminum frame with sporty geometry
🌬️ (Fork) Air suspension suspension fork with lock-out – comfort and control, even off-road
🔗 (Drivetrain) 9-speed SRAM X5 derailleur with easy-to-use shifter – perfect for climbing and descending
🛞 (Tires) Schwalbe Rocket Ron – grip, speed, and low rolling resistance
🛑 (Brakes) Hydraulic disc brakes – kid-friendly levers with maximum control
🚴♂️ (Cockpit) Flat aluminum handlebars for a sporty riding position, extra balance, and confidence

Whether you’re bouncing over tree roots, tearing through the leaves, or just blasting down a gravel path: the OFF AIR 4 gives kids the real mountain biking experience. Not a toy, but a serious bike—built for small bodies and big dreams.
