Features & highlights

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).

What's in the box?

Our woom bikes don't come with any additional accessories. You can find useful extras, including kickstands, in our online shop.

If your child plans on cycling on public roads and streets, their woom bike may need to meet certain standard requirements before it can be considered legal in your country of residence. In many countries, bikes must be equipped with a bike bell, front and rear lights, and wide-angle Z reflectors. As rules for cyclists and their equipment vary from country to country, find out about the regulations applicable to riding a woom bike in road traffic in your country or region, particularly regarding the use of lights, reflectors and other obligatory safety equipment.

Members of our woom Riders Club can extend the warranty on aluminum frames, rigid forks, handlebars, stems and cranks to 10 years for free by registering their bike within 9 weeks of buying it.

Ratings & Reviews

I got the Woom up 5 for my 8 year old birthday. I was quite excited about it, but it seems that the bike came damaged. The back derailer was bent and the front part had scratches on it. Some parts were missing (the hex to assemble the bike). I'm trying to get a response from customer service on support (they were quick to respond when I was buying the bike, but are taking time on post sales service). Be attentive when you receive your bike if it's really in good conditions, seems that could be a hit or miss. I also got the Woom 4 go for my younger son and it was a big success, he really enjoyed it.

Good Afternoon Jorge, Thank you for your review and I am sorry to hear about the condition the bike arrived and will absolutely be following up on how we can do better in response time. We want you to love your UP bike and I see our CX team is in contact to help get this fixed. We look forward to finding a solution that works for you and your rider.
