RFN Warrior Kids SX-E500 Electric MX Bike
The RFN Warrior SX-E500 is the next-level electric motocross bike designed for young thrill-seekers aged 3–6. Combining added motor power with trusted RFN durability and child-focused safety, it offers an exhilarating step up from entry-level models.
Upgraded 500W Brushless Motor
Fitted with a robust 500W brushless motor, the SX-E500 delivers stronger acceleration and enhanced torque for off-road fun. Its chain-driven system ensures consistent power and a more exciting ride for slightly more experienced young riders.
Three Adjustable Speed Modes
Tailor the speed to your child’s confidence and riding ability with three built-in modes:
-
Eco Mode: 5 mph (8 km/h)
-
Standard Mode: 7.5 mph (12 km/h)
-
Sport Mode: 15.5 mph (25 km/h)
These options allow gradual skill development in a safe and controlled way.
Long-Lasting Removable Battery
Powered by a 36V 5.2Ah lithium-ion battery, the SX-E500 delivers up to 11 miles (18 km) of ride time or 2 hours in Eco Mode. The battery is removable, allowing easy indoor charging and convenient swaps for extended fun.
Durable Lightweight Frame
Made with high-grade carbon steel, the frame strikes the perfect balance between durability and weight. At only 18 kg, the bike remains light and manageable for small riders while standing up to off-road use.
Advanced Safety Features
Safety remains a top priority, with features designed to protect young riders:
-
Lanyard Safety Cut-Off: Automatically cuts power if the rider separates from the bike.
-
Ignition Lock Cover: Prevents unauthorized starts.
-
Enclosed Chain Guard: Keeps the drivetrain covered to protect hands and clothing.
Premium Suspension and Tires
Equipped with front and rear spring suspension, the SX-E500 provides a smooth, stable ride on dirt, grass, or gravel. The 12″ anti-slip tires offer superb grip and stability across varied terrain.
