Product Overview
Introducing the RFN WARRIOR YOUTH SX-E5 Electric Dirt Bike – The Next Generation of Off-Road Power
Get ready to unleash serious performance with the RFN WARRIOR YOUTH SX-E5, a high-torque electric dirt bike designed for youth riders who are ready to graduate from toy-grade bikes to serious machines. Combining cutting-edge technology with race-ready features, the SX-E5 offers a ride that rivals and in many ways outclasses traditional 50cc petrol bikes.
Electric Muscle with Unmatched Torque
At the heart of the SX-E5 lies a 5kW Peak Output Motor, delivering an impressive 7 horsepower and a ground-gripping 145Nm of torque. With a top speed of 60 km/h, this electric warrior doesn’t just keep up with combustion-powered 50cc bikes it blows them away in acceleration and responsiveness, all without the noise, heat, or fumes.
High-Capacity Swappable Battery
Powered by a 48V 25Ah Lithium-Ion battery (1,200Wh), the SX-E5 offers a range of up to 40km at a steady cruising speed of 35 km/h. When the adventure’s not over, a 4-5hour fast charging system and swappable battery design mean you can be back on the trails in no time.
Built for Real Off-Road Riding
Equipped with a 12” front and 10” rear knobby tire setup, the SX-E5 is ready to tackle everything from backyard dirt tracks to proper off-road trails. With 205mm of front suspension travel and 180mm rear travel, it soaks up bumps with ease and delivers a smooth, controlled ride ideal for developing skills in comfort and confidence.
Lightweight and Rider-Friendly
Weighing just 47kg, the SX-E5 is much lighter than petrol equivalents, making it easier for younger riders to handle, balance, and pick up if dropped. The adjustable seat height (615–665mm) ensures a perfect fit for a growing rider.
Clean, Quiet, and Low-Maintenance
Unlike petrol bikes, there’s no engine noise, no hot exhaust pipe, no fuel mixing, and no oil changes. That means less time maintaining, more time riding, and a safer, cleaner experience for both kids and parents.
Safety-First Features
Hydraulic Disc Brakes (Front & Rear) for reliable stopping power, Three-Speed Ride Modes for rider progression and parent-controlled limits, Steel Frame Construction for off-road durability, Electronic Controller with Advanced Motor Algorithms for smooth throttle control.
Electric vs Petrol: Why the SX-E5 Wins
Compared to a traditional 50cc petrol dirt bike, the SX-E5 offers:
✅ More Torque: Instant power delivery for better climbing and off-the-line acceleration
✅ Lighter Weight: Easier to maneuver and recover after falls
✅ Zero Noise: No screaming engine, great for suburban or shared-use trails
✅ No Hot Exhaust Pipe: Safer for young riders learning to ride and dismount
✅ No Fuel or Oil: Just plug, charge, and ride simple, clean and future-ready
The Verdict
The RFN Warrior SX-E5 isn’t just a step up it’s a leap forward into the future of off-road riding. It delivers all the thrills of a 50cc petrol bike with fewer headaches and far more innovation. Perfect for young riders ready to progress, this bike is a serious machine designed for serious fun.
