RFN WARRIOR SX-E5

RFN Warrior SX-E5 Electric Dirt Bike

The RFN Warrior SX-E5 is built for young riders who are ready for more than a basic starter bike. With legit power, adjustable sizing, and a chassis designed to handle real off-road riding, this is the kind of bike that helps kids build confidence while still leaving plenty of room to grow.

From backyard laps to real trail riding, the SX-E5 brings a serious mix of performance, durability, and fun without feeling intimidating for developing riders.

Why the RFN Warrior SX-E5 Stands Out

Strong brushless power
The SX-E5 is powered by a 5kW brushless motor that delivers smooth, responsive power and impressive rear-wheel torque. It has the punch to tackle hills, rough terrain, and faster-paced riding while still being manageable for younger riders.

Built to grow with your rider
One of the best parts of the SX-E5 is its adjustable geometry and ride height. The seat height and rear subframe can be adjusted as your child grows, making this a bike that can stick around longer instead of being outgrown too quickly.

Real suspension for real riding
With dual-adjustable damping shocks, the SX-E5 is ready for more than just smooth ground. It is designed to handle bumps, uneven terrain, and off-road abuse better than many youth bikes in this category.

Lightweight but tough chassis
Built from new-generation BIK500 high-strength steel with a 6061 aluminum alloy rear swingarm, the frame is lighter than traditional steel designs while still staying strong where it matters. That means better handling, better control, and less dead weight.

Battery built for longer rides
The 48V 25Ah lithium battery uses Samsung 50S high-rate cells for strong power delivery and dependable performance under load. It is designed to stay consistent when the riding gets aggressive and is protected with thermal management, shock resistance, and waterproof sealing.
