Gear it up!
The woom 4 introduces the world of gears to kids aged 6 to 8. The woom 4’s eight-speed gearing combined with the easy-to-operate twist shifter opens up a whole new world of discovery on two wheels. The superlight frame combined with kid-specific geometry creates a comfortable riding experience and gives your Rider more confidence. Being able to ride longer distances and climb bigger hills means your child can go where they’ve never gone before.
All components that have been specifically designed with safety in mind bear the KIDSAFE PLUS seal.
“There is much more to riding a bike than just the fun of taking it for a spin: exploring the world means broadening horizons.”
