Carrera Blast Junior Mountain Bike – built for off-road confidence
The Carrera Blast Junior is a 24” wheel mountain bike designed for children aged 8–12 (127–144cm tall). With a strong but lightweight aluminium frame, front suspension and grippy off-road tyres, it’s a great choice for young riders ready to explore beyond smooth paths.
A 14-speed Shimano drivetrain with Revoshift shifters makes it easy to find the right gear on climbs or flats, while disc brakes deliver reliable stopping power in all conditions. Adjustable components, including the seatpost and brake levers, mean the fit can be tailored as your child grows, while the junior-specific saddle ensures all-day comfort.
Carrera has over 25 years of experience designing and testing bikes in the UK, and their junior range is built to be durable, practical and fun to ride. At around 14kg, the Blast is sturdy yet manageable, giving children the confidence to tackle hills, trails and everyday cycling.
Perfect as a first proper mountain bike or as a step up to more adventurous riding, the Carrera Blast combines performance, safety and value to help kids build skills and enjoy their time on the bike.
