Woom kids bikes are one of our favorites because they make riding fun and accessible for little ones. Start with a balance bike, and graduate to a bike they can ride, not a tank that is impossible to figure out. The light weight, easy-to-pull, color-coordinated hand brakes, chain guard and padded bar ends make it easy for small children to enjoy bikes just like we do. They are also highly adjustable and easy to maintain.

From Woom:

The woom 4 introduces children aged six years to the world of gear-shifting. The bike's seven speeds in combination with the easy-to-operate twist shifter expand the bike's range of use and increase the child's mobility. Whether they want to ride their bikes into the woods or up hills – the new-found freedom of gears make longer adventures on two wheels child's play.

Lightweight Aluminum Frame

Geometrically designed for kids six and up and forged of sturdy superlight aluminum, the frame is the heart of the bike. The low standover makes getting on and off the bike easy. The light weight means your Rider can go further, faster, and higher than ever before.

Safety-Focused Brakes

With climbing big hills come big descents. The woom 4 comes with independently operated front and rear V-brakes to ensure that whether your Rider is bombing down that big hill they conquered or making their first forays off the pavement, they can always control the bike safely. The two V-Brakes are easy to operate thanks to their ergonomically adapted brake levers with reach adjustability.

woom Crank

The crank length and distance between the pedals are ergonomically adapted to fit children's bodies. This results in an optimal stance and very natural movements. And thanks to the chain guard those days of getting your pant leg caught are over!

Ergonomic Contact Points

Comfort is very important to the riding experience and that's why the contact points on our bike are made specifically for kids. The saddle is designed to accommodate a young child's anatomy and biomechanics. The grips are ergonomically designed for kids' hands. The pedals are durable, reflective, and slip-resistant. 

Quick-Release Seatpost Clamp

The quick-release seatpost clamp offers a simple, quick and tool-free way to adjust the saddle height. It's even easy enough to be operated by children. On your pedals, ready, go!

High-Quality Tires

The high-quality Schwalbe Little Joe tires provide plenty of traction and durability. The 20” diameter, 1.4″ width tires allow your Rider to traverse both pavement and dirt with plenty of control. The reflective sidewalls of the tires give them further visibility on darker rides.

Tailor-Made Wheels

The woom SOOPA DOOPA HOOPS are specially designed for the child-specific geometry on the woom 4 and feature our smooth, frictionless hubs and double-walled rims. The rims come with a 20 stainless steel spoke design to offer a perfect balance of strength and lightweight.

Adjustable Vario Stem

Kids grow fast and need a bike that adapts to them. The Vario stem is constructed of lightweight forged aluminum, making it quickly and easily adjustable. Our Vario stem allows your Rider to optimize their riding position as they become taller. By extending the reach of the handlebars, the life of the bike is also extended.
