New Woom OFF 4 | 20 inch | 6-8 years | 115-130 cm

Get out and explore!
The woom OFF 4 gives children aged six years and older a superlight and durable mountain bike for their first go on the pump track and easy cruising through forests and fields. The kink in the top tube makes it easy to get on and off quickly in any situation, thereby giving kids greater safety out and about on the trails. The perfect introduction to mountain biking.

Woom frame
The superlight aluminium frame with butted hydroformed tubes has a sporty geometry, long wheelbase and flat steering angle. The kink in the top tube makes it easy to dismount quickly in any situation.

Fork
Superlight and super stylish – the carbon fork offers maximum stability with minimum weight. Multidirectional carbon fibres ensure plenty of torsional strength when steering and braking. That makes the bike strong and stable even on the roughest terrain.

Brakes
The disc brakes with their excellent modulation combined with special brake levers designed for children's hands increase safety and control in all situations, including on rough terrain and in wet conditions.

Stem
The specially developed stem from forged aluminium guarantees maximum stiffness with minimal weight. Thanks to its flip-flop design it can be turned over and mounted upside down to adjust the handlebar height.

Woom saddle
The saddle is one of the most important points of contact between the child and the bike. It significantly affects the feeling when riding. That is why we have designed our saddle to fit the pelvis of children and give them a slightly stretched riding position. Perfect for a unique riding experience!

Gears
The precise and easy-to-operate gear system allows smooth shifting. The SRAM X5 system has nine gears suitable for a wide range of gradients thanks to 28 teeth in the front and an 11-32 cassette in the back.

Tyres
The high-quality Schwalbe mountain bike tyres with ADDIX SPEED rubber compound offer an ideal combination of low rolling resistance, maximum grip, good shock absorption and excellent durability.
