The Woom OFF AIR 4 (Black) is a lightweight 20″ trail bike built for riders aged 6–8 (approx. 115–130 cm) who want added comfort and control on rougher terrain. As part of our wider range of kids’ bikes, the OFF AIR 4 combines a superlight frame with front suspension for young riders ready to explore real off-road trails. You can explore the full Woom range here to compare rigid and suspension models.
The woom OFF AIR 4 is built for young riders who want more comfort and control on rough terrain. With its lightweight frame, air-sprung suspension fork, and confident geometry, it delivers smooth, stable performance on roots, rocks, and bumpy woodland tracks—perfect for riders beginning to explore real mountain biking.
The OFF AIR 4 features an air-sprung suspension fork with adjustable rebound, allowing young riders to fine-tune their setup for comfort and control. It absorbs trail vibrations and bumps effortlessly, giving kids the confidence to ride faster and smoother on uneven terrain.
Equipped with powerful hydraulic disc brakes, the woom OFF AIR 4 delivers predictable, responsive braking in all conditions. The child-specific levers ensure that even smaller hands can modulate speed precisely, helping riders stay safe on steep descents and technical tracks.
The 9-speed SRAM drivetrain provides young riders with the gear range they need to climb confidently and maintain speed on rolling trails. Smooth shifting helps kids stay in control while learning to master more technical riding and changing trail gradients.
Fitted with Schwalbe off-road tyres, the OFF AIR 4 offers superb traction on dirt, gravel, and forest paths. The tread pattern enhances grip while keeping rolling resistance low, making climbing easier and cornering more stable for young trail riders.
Every detail—from narrower handlebars to shorter cranks and a youth-specific saddle—has been designed around the needs of children aged 6 to 8. The balanced geometry keeps riders centred and in control, making it easier to navigate technical terrain with confidence.
The unique flip-flop stem lets riders fine-tune handlebar height as they grow, ensuring the perfect fit through several years of riding.
If a lighter rigid setup is preferred, the Woom OFF 4 offers similar trail geometry without front suspension. As riders grow, they may be ready for the Woom OFF AIR 5 or Woom OFF AIR 6.
Pair it with a Woom Helmet and Woom accessories for the complete setup. Fast UK delivery available.
