What's in the box?

Our woom bikes don't come with any additional accessories. You can find useful extras, including kickstands and mudguards, 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.

Ratings & Reviews

4.70Based on 40 reviews

The Woom4 Explorer is now our son's third bike (115cm). Assembly is problem-free, he got along with the circuit very quickly. As expected, it is great. Only the installation of existing lighting makes it difficult. Ideal for the back, a variant should be directly under the saddle. For the front, a place for reflector and lamp, no matter how you place it on the handlebars, it is not optimal, becomes loose, interferes, sits crooked. The frame is too thick for mounting.

Hi Seb, Thank you so much for your honest feedback. Please contact our customer service directly and we'll be happy to give you a few tips for installing the lighting. Your woom team

Main or Tool Design has to be check

In terms of its overall appearance, the bicycle is very stylish and attractive, but there are some issues regarding its usability that need to be addressed. 1. There is no suitable spot on the handlebars—like on the "original version"—to mount a reflector. No matter where you attach it, the front reflector slips downward and shifts out of position during use—even when simply riding up or down small curbs—which is a negative point for me in terms of safety. 2. When attempting to attach it to the painted section of the main frame, it damages the paint, and the rubber strap is not the right size—it is too short. 3. The same issue applies to the red tail light. Attaching the red reflector to the tube under the saddle leaves no room for the red light, yet mounting it on the painted area under the saddle makes it invisible due to the mudguard. Furthermore, when the saddle is set to its lowest position—necessary for the rider's height—there is no suitable space to mount both attachments.

My child was absolutely delighted with the bike. He is 5 years old and 115cm tall, which is why we chose the Woom Explore 4. The best decision we could make. Easy to assemble and a great material Clear recommendation!

Woooooom

The only negative thing that has stood out so far was that the gearshift was not set correctly upon delivery. However, after a quick phone call, I was immediately informed that I could submit the invoice for the recruitment by a specialist retailer and get the costs reimbursed. The customer service was therefore very uncomplicated and accommodating. Even though the bike is quite light, it is not necessarily pleasant to carry it to the second floor of an old building. However, this is due to our living conditions and not to the bike itself. My daughter loves cycling and loves riding it.

Great bike!

My son loves his woom Explore. The gearshift is easy to operate and the disc brakes work perfectly. I was skeptical at first as to whether they would not require too much maintenance, but even after half a year with various falls, nothing is grinding and the brakes continue to work reliably. Very happy so far!

A nice high-quality bike

My son (7) is an enthusiastic cyclist and easily rides over 20 km on our bike tours without complaining! Are he considering buying an e-bike in summer 2027, when his bike actually becomes too small.

WOOM EXPLORE 4

We are super happy with the bike. Our child could easily handle the gearshift right away. As always, this bike is relatively light so that our child can carry it up or down smaller steps themselves. The disc brakes also work great, so that our child can brake super quickly even at faster speeds. Our child has great fun with this bike.

The best buy for our child!

Our son loves his Woom EXPLORE 4! It was by far the best gift. The bike looks beautiful and attracts attention everywhere — we are regularly asked which model it is. More importantly, our son really enjoys driving. The bike is lightweight, comfortable and provides a great ride experience. Since then, he likes to ride a bicycle even more often. Absolute recommendation!

Excellent bicycle series

My grandson rode a Woom balance bicycle for several years. Recently, I bought him a Woom bicycle with pedals for his 6th birthday. He was riding it on his own within minutes of receiving it! I am beyond thrilled with y’the Woom bicycle series!

Excellent bike

Daughter had 8 km ride (hills and downhills, but nothing extreme) today in contest. Ride was smooth and she said it was really eeasy to ride. Needed some time to adjust to speed change (and still needs more practice)
