Suspension fork
Comfort and control on the bumpiest terrain is a given thanks to the high-quality suspension fork, which can be adjusted to the rider’s weight. Tune the feel of the bike to suit the terrain with adjustable compression and rebound damping, plus lock-out the suspension when needed. These features ensure a good time, whether your child is shredding up the trails or cruising home.
"What starts as a natural urge to move develops over the course of childhood into a love of sport – and for this important development phase we have designed the ultralight woom OFF and woom OFF AIR mountain bike."
