2026 RFN Warrior Kids SX-E5 Kids - 48v 5kw Electric Dirt Bike

Dominant in its class - the RFN Warrior SX-E5

We are fully aware that kids grow up FAST! Families have grown sick of buying a new bike every other year for their rapidly growing young riders. We were sick of it too, so we designed the E5 to grow with the rider and it is now the ultimate upgrade from 50cc, 70cc and 90cc gas dirt bikes. This unprecedented innovation in dirt bike technology is done with an adjustable seat height, complete control over top speed, torque, regenerative braking, and more through the RFN app. This bike can truly be crafted to every young rider whether they're a backyard warrior or an up and coming world champion.

The E5 delivers instant torque and perfectly balanced power for riders ready to take the next step. Its advanced 48V system and precision-tuned throttle provide a smooth, controlled, and thrilling ride—no clutch, no gears, no engine heat. Batteries can be swapped quickly and easily, allowing young riders to gain confidence and build skills while having more fun than ever before.

Gain back hours of your precious time from fixing your kids bike in the garage. With minimal maintenance, zero emissions, and whisper-quiet performance, you can finally ditch the gas cans and oil funnels and spend that precious time riding with your kid. Every component, from its lightweight frame to its race-tuned fully adjustable suspension geometry, was engineered to outperform the competition on both track and trail.
