Bike life begins here

safety first

Very cool features

  • 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.
  • Woom Ergonomic Crankarms
    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.
  • 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.
  • Supportive 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. Now your child can really get the most out of their ride!
  • 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.
  • Bike fit guide on bars and post
    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?!
  • 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.

    FAQ

    Frequently Asked Questions

    Woom bikes are designed for kids aged 18 months to 8 years. Check the product specifications to find the right size and recommended age.
    We offer a standard 2-year warranty that applies automatically from the day you buy a new woom bike. You need to provide the purchase receipt to make a claim under the warranty. Make sure you keep it somewhere safe.
    On a new bike, the Bowden cable is still pretty tight. It will stretch by itself after applying the brakes a few times. If the brakes are too tight, you can easily loosen them by turning the adjustment barrel on the Bowden cable. This will release the tension and open up the brakes. If only one brake pad is rubbing, you can adjust the spring tension on the brake. Our mechanic Tim explains exactly what you need to do in our video about adjusting the brakes.
