Description

Woom Off Air 4 is a mountain bike with an air—cushioning fork for children aged 5 and older. Aluminum frame, carbon fork and wide tires for forest and mountain trails, pamptrack and skiing in all conditions.

The fork with the Woom air shock absorber smooths out both large relief elements and small irregularities and is adapted to work with a small child's weight, has a rebound adjustment and a lock. Thanks to the ability to adjust the pressure in the air chamber, the plug can be precisely adjusted to the weight of the child.

The Woom Off Air 4 model has a reliable 9-speed SRAM X5 transmission with a convenient trigger carriage, giving the child the necessary gear range to ride on the most difficult terrain.

The Woom Off Air 4 model is equipped with 2.25" wide Schwalbe Rocket Ron tires, which ensure a reliable grip even on loose soil or snow. Tires can be used with low pressure for a very gentle ride, or, conversely, with high pressure for a better roll. The Rocket Ron version with the most rolling ADDIX SPEED compound is used.

The wheels of the Woom Off Air 4 model with a diameter of 20" are mounted on bushings with industrial bearings, high-quality stainless steel spokes and aluminum rims. The bushings are mounted on axles with minimal rolling resistance and high torsional rigidity.

Features

woom Frame

The superlight aluminum frame with butted hydroformed tubes has impeccable MTB genes with modern geometry, a long wheelbase and a slack head tube angle.
The kink in the top tube makes it easy to dismount quickly in any situation.

woom Carbon Fork

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

Stem

Specially developed from forged aluminum, the 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.

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 getting the most out of their ride!
During a redesign of our products, the security seatpost clamp shown here was replaced with a quick-release seatpost clamp. The result: quick and easy saddle height adjustments – no tools required.

Tires

Built with the ADDIX SPEED rubber compound, the valued Schwalbe mountain bike tires deliver the ultimate performance, uniting a low rolling resistance with superior grip, cushioning and durability.
