Product Description
The 2025 Radius Explosive Mini 20 Inch is a tough and reliable junior bike designed for young riders who are ready to explore further with confidence. Perfect for riding around the neighbourhood, bike paths and local parks, it combines durable construction with simple, easy to use components that help build riding skills.
Built around a boys specific hi tensile steel frame with a low standover height, the Explosive Mini provides stable handling and an upright riding position for improved comfort and confidence. The rigid steel fork keeps the bike lightweight and responsive, while the junior saddle and youth specific grips ensure a comfortable ride.
A Shimano 6 speed drivetrain with RevoShift shifters allows smooth and simple gear changes, making it easier for young riders to tackle hills and changing terrain. Alloy V brakes with junior short reach brake levers provide dependable stopping power, while the 20 inch tyres deliver excellent grip on sealed roads, bike paths and park trails. Complete with a kickstand, the Radius Explosive Mini is ready for everyday adventures.
