Woom EXPLORE 4 20-inch kids' bike
The Woom EXPLORE 4 is a lightweight 20-inch kids' bike for riders aged 6–8 years and 115–130 cm tall. Designed for family rides, gravel paths and light trails, it combines a sporty aluminium frame with practical features for children ready to explore beyond tarmac.
Seven gears and a Shimano Revoshift twist shifter help young riders manage changing gradients.

In-Store/Warranty:
Ships mostly pre-assembled — around 5 minutes to complete setup. Covered by our standard 2-year warranty on frame and components; woom Riders Club members can extend frame/fork/bar/stem/crank cover to 10 years free of charge if registered within 9 weeks. A LEGGIE Kickstand, PICKUP Rack, SNAP mudguards and frame sticker sets are available as add-ons. Disc brakes need slightly more occasional maintenance than the GO range's rim brakes, but offer stronger, more consistent stopping power — good for kids riding off tarmac. Free fit check in-store.
