The new 20” woom OFF 4 provides off-road capability in a lightweight package with ergonomics that are designed specifically for children.
NOTE: You won’t be able to upgrade the woom OFF to an air suspension fork later on. If you think your rider would benefit from suspension, consider the OFF AIR.
The ultralight mountain bike by woom is designed with a minimal weight, off-road comfort and maximum fun for kids aged 6 to 8.
