Description
Small in size, big on first-bike fun. The RFN Warrior SX-E400 is a 12-inch electric motocross bike designed to give young riders a controlled, confidence-building introduction to off-road riding. Its quiet 36V electric powertrain, twist throttle and three selectable speed modes let the bike's performance develop alongside the rider.
Eco, Standard and Sport settings offer top speeds of approximately 5mph, 7.5mph and 15.5mph. In Eco mode, the 36V 5Ah lithium battery can deliver up to 11 miles or approximately two hours of riding, depending on rider weight, terrain and conditions. Direct chain drive provides smooth, efficient power delivery, with up to 400W peak power and 26Nm of rear-wheel torque.
Built around a high-grade carbon-steel race frame, the SX-E400 features RFN spring suspension, wide anti-slip tyres and a 140mm rear disc brake. A safety lanyard cuts the power if the rider separates from the bike, while the covered power control helps parents manage the selected setting.
