Innovative frame

The superlight aluminum frame is the heart of the bike. Its smart geometry with low entry and upright riding position allows your child to get on, ride and get off again safely. The long wheelbase and forgiving front-end geometry provide them with stability and guarantee a smooth ride.

Child-specific hand brakes

Your child won't struggle to bring their woom GO 4 to a stop even if their hands aren't very strong. That's down to the high-quality brake cables, the ergonomic brake levers and the small (but mighty) barrel adjuster that you can use to set the right distance between the brake lever and the handlebar grip for your child.

Protective handlebar grips

Our high-quality handlebar grips have a narrow diameter and an ergonomic design so your child can comfortably hold on with a good grip. The special material and extra large outer diameter keep your child safe, reducing the risk of them getting injured if they do happen to fall.

Ergonomic cranks

The length of the high-quality cranks and the distance between the pedals have been perfectly adapted to fit with children's bodies. This results in an optimum stance and natural movements that feel good. And there's no risk of your child getting their trouser leg caught thanks to the chainguard ring.

Intuitive twist shifter

Your child will get to grips with the gears in no time thanks to the easy-to-use twist shifter and the child-friendly gear indicator. They can shift to the next highest gear by twisting the shifter forward. And the little rider on the gear indicator will move toward the hare to show that your child is going faster. A twist back will shift the gear down again and the little rider will move toward the tortoise to show that your child is slowing down – perhaps because they're tackling a climb.

Handy quick-release skewer

The quick-release mechanism on the front wheel axle makes fast and easy work of dismounting and mounting the front wheel, so you can transport the woom GO 4 by car with no trouble at all.

Ergonomic saddle

The saddle has a major influence on the feel of the ride. And that's exactly why we carefully designed our saddle to suit the pelvis of children in the relevant age group and unlock ultimate comfort. Seriously – your child's ride couldn't be more comfortable!

Practical quick-release seatpost clamp

The quick-release seatpost clamp gives you – or even your child – a simple, quick and tool-free way to adjust the saddle height with perfect precision. On your pedals, get set, go!

All-round capable tires

Tires have a major influence on how a bike handles. That's why we've chosen tires that can be used on all kinds of terrain for the woom GO 4. Our lightweight tires will ensure maximum grip in any weather and on any surface so your child can confidently cover gravel, tarmac and dirt, riding in a straight line or taking corners along the way.

ABC markings for adjusting the handlebars/saddle on the woom GO 4 children's bike

Bike fit guide on handlebars and seatpost

The ABC markings on the handlebars and seatpost make it easier for you to precisely adjust the woom GO 4 so the bike can grow with your child. Start by moving the saddle up or down so that your child can touch both feet to the floor and pedal comfortably. Match the handlebar marking to the seatpost and your child is good to go. How easy is that?!

Our woom bikes don't come with any additional accessories other than the front and rear reflectors. We automatically ship all woom bikes from size 2 and upwards within Italy only with bike lights and a bell to ensure compliance with the law. No further accessories are supplied with bikes in Italy. 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.

Our standard 2-year warranty applies to the frame and components automatically from the day you purchase your woom bike. 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.

If you buy a woom product and are not 100% satisfied, or if you didn't order the right size, you have 30 days to send it back to us free of charge from within the EU for either a refund or an exchange.

This also applies to your new woom bike, even if your child has already ridden it.
We will cover the return shipping costs and either refund the full amount you originally paid or send you a new bike in the requested size.
