Gear it up!
The woom 4 introduces children aged six years to the world of gear-shifting. The bike's eight 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.

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.”
