70cc MJM Dirt Bike Blue Steel with Semi-Auto Transmission and Robust Hydraulic Brakes for Confident Off-Road Adventure

Take your young rider’s off-road adventures to the next level with the MJM 70cc Petrol Powered 4-Stroke Semi-Auto Kids Dirt Bike – Blue. With smooth power, stable handling and a bold blue finish, this model is perfect for kids ready for a more capable and exciting outdoor ride.

The 70cc 4-stroke engine delivers steady, manageable power, while the semi-automatic transmission lets riders change gears without the complexity of a manual clutch. Paired with an electric start, this setup makes riding easier, smoother and far more confidence-building for developing riders.

Built with strong steel construction, upside-down forks, a heavy-duty rear shock and chunky off-road tyres, this dirt bike is made for backyard trails, dirt paths and uneven terrain. Its hydraulic disc brakes offer reliable stopping power, making it a great fit for supervised off-road fun.

Features and Benefits

  • Smooth 70cc 4-stroke engine for steady, predictable power
  • Semi-automatic transmission for simple, clutch-free gear changes
  • Electric start for quick and easy operation
  • Hydraulic disc brakes (front & rear) for reliable stopping
  • USD front forks and heavy-duty rear shock for improved stability
  • Knobby 80/100-10 tyres for strong off-road traction
  • Chrome performance exhaust for responsive throttle feel
  • Durable steel frame and steel swing arm for long-lasting strength
  • Blue dress-up parts for a bold, standout look

Smooth, Beginner-Friendly Power

The 70cc engine gives riders more power without sacrificing control. The semi-automatic gearbox provides the feel of shifting but removes the challenge of using a clutch, making it a great transition bike for young riders progressing in skill.

Stable and Ready for Rough Terrain

This dirt bike is built to handle outdoor ground conditions. The upside-down forks and strong rear shock help absorb bumps, while the knobby tyres keep grip steady across dirt tracks, gravel and uneven terrain.

Hydraulic Brakes for Confident Control

Front and rear hydraulic disc brakes give young riders reliable stopping power — essential for safety on off-road tracks. Soft grips and easy-reach levers help keep braking smooth and controlled.

Durable Build Designed for Adventure

From its heavy-duty steel frame to the reinforced swing arm and protective chain cover, this dirt bike is made to withstand regular outdoor riding. The blue styling adds a sleek, sporty touch that kids love.

Safety Note
