The Woom Explore 4 20" Kids Bike is a superlight all-round bike for children aged six and up. It has hydraulic disc brakes, 7 gears, and Schwalbe Billy Bonkers all-terrain tyres. The lightweight aluminium frame, child-specific fit, and balanced handling help young riders build skill on paths, roads, and light trails.
Key Features and Benefits:
- Lightweight aluminium frame: The AA 6061 aluminium frame uses butted tubes to reduce weight without losing strength. This helps keep the bike easy to handle, lift, and control, which gives young riders more confidence.
- Hydraulic disc brakes: The Promax flat mount disc brakes use 140 mm rotors at the front and rear. They give smooth, strong braking with less hand effort, which helps children slow down with better control.
- 7-speed Shimano gearing: The Shimano Tourney rear derailleur and Revoshift twist shifter give a simple 7-speed range. This helps children pick the right gear for climbs, flat paths, and faster sections, so riding feels more natural.
- Schwalbe Billy Bonkers all-terrain tyres: The 20 x 1.5" folding tyres offer grip, low rolling resistance, and reflective sidewalls. This gives the bike steady traction on mixed surfaces, with added visibility in low light.
- Adjustable cockpit fit: The forged aluminium stem adjusts in height and reach, while ABC markings help align the bars and saddle. This supports a better fit as the child grows, which helps comfort and control last longer.
- Child-specific contact points: The saddle, grips, handlebars, and brake levers are shaped for smaller riders. This improves hand comfort, reach, and body position, which helps reduce strain on longer rides.
The Woom Explore 4 is built to make each ride easier to manage. Its low 7.8 kg weight helps with handling, while the narrow Q-factor cranks support a natural pedalling position. Sealed bearings in key areas help keep the bike running smoothly, and the quick-release front wheel makes transport and storage easier.
Choose the Woom Explore 4 20" Kids Bike for a light, capable, and practical step up for young riders who need gears, disc brakes, and all-terrain grip in one well-sized bike.

This also means an express delivery service is unavailable. We strive to despatch bikes within 3-5 working days. Please note this may change over school holidays and the festive season (November/December). For more information on the process please visit our pre-build page.
