Ready for the Next Adventure
The RFN Warrior Kids SX-E800 is a lightweight electric motocross bike designed for young riders ready to take their off-road adventures further. With its rugged motocross styling, responsive electric performance and 16-inch wheels, the SX-E800 offers a natural step up from smaller children's electric bikes. Designed for riders aged 6 and above, it combines the excitement of motocross with simple, easy-to-manage electric power.

Three Speeds. More Confidence.
Powered by an 800W electric motor producing up to 900W of peak power, the SX-E800 delivers smooth, responsive acceleration with a top speed of 21.5mph. Three selectable riding modes allow parents to adjust the performance to suit the rider's experience, with Eco limited to 9.5mph, Standard to 15.5mph and Sport offering the full 21.5mph. As confidence and riding ability improve, the SX-E800 is ready to keep up.

More Riding. Less Waiting.
The SX-E800 features a 36V 7.5Ah lithium-ion battery, providing up to 10.5 miles of range in Eco mode, or approximately one hour of riding under suitable conditions. A full recharge takes around 2.5 hours, making it easy to get ready for the next adventure. With no petrol, clutch or gears to worry about, the SX-E800 keeps riding simple and maintenance to a minimum.

Built for the Dirt
Designed for grass, dirt and light trails, the SX-E800 features a strong carbon steel frame, 16-inch magnesium alloy wheels and motocross tyres for grip across varied terrain. RFN front suspension and a Fast Ace rear shock help absorb bumps and uneven surfaces, while front and rear hydraulic disc brakes provide dependable stopping power. With a 550mm seat height and a weight of just 20kg, the SX-E800 offers a manageable platform for developing off-road skills.

Fun with Control
The SX-E800 combines proper motocross styling with features designed specifically for younger riders. An electronic twist throttle makes power delivery straightforward, while the adjustable speed settings give parents greater control over performance. A safety lanyard cuts power if the rider becomes separated from the bike, providing an additional safety feature as children develop their riding skills. Quiet, responsive and built for off-road enjoyment, the SX-E800 is a great introduction to the next level of electric motocross.
The RFN Warrior Kids SX-E800 is an off-road-only electric bike. It is not road-legal and must only be ridden on suitable private land with the landowner's permission, appropriate supervision and protective equipment.
