WOOM UP 5
Pedal-assist for kids
The smooth Fazua drive system provides a natural riding feel without any pedaling resistance – across all three assistance modes. The compact and lightweight combined motor and battery unit is subtly integrated into the down tube and can easily be removed if required (optional downtube cover available from Fazua).
Superlight 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.
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 – and lock out the suspension when needed. Good times are guaranteed whether your child is shredding up the trails or cruising home.
Reliable disc brakes
Easy-to-modulate disc brakes are teamed with special brake levers designed for children's hands to provide maximum stopping power in every situation including steep slopes and wet conditions.
Ergonomic contact points
The age-appropriate MTB saddle and ergonomically profiled handlebar grips make the ride more comfortable for your child, while the hard-wearing platform pedals with metal pins provide the necessary grip for all-terrain riding.
Smooth gear shifting
The precise SRAM NX drivetrain has eleven gears and offers a wide gear range for help in the hills. The easy-to-operate trigger shifter makes light work for children’s thumbs by shifting efficiently through the gears with precision.
Grippy tubeless-ready MTB tires
High-quality Schwalbe mountain bike tires combine low rolling resistance with superior grip and proven durability. With Tubeless Easy technology and tubeless-ready rims, it’s a straightforward transition to go tubeless and benefit from added comfort and grip.
Widely adjustable components
With a handy quick-release seatpost clamp to change the saddle height in seconds, reach-adjustable brake levers for kids’ hands and a flip-flop stem that can be inverted to adjust the height of the bars, this bike grants wide flexibility when it comes to fitting the bike to the child (and their finger length).
