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


Description

The RFN Warrior SX-E5 is a high-performance electric dirt bike built specifically for young riders aged 8-12 who are ready to push beyond beginner territory. Powered by a 5kW geared permanent magnet motor and a 48V 1200Wh lithium battery pack loaded with Samsung 50S cells, this bike delivers explosive acceleration and a real-world range of up to 18.64 miles - more than enough for a full day on the trail. With a top speed of 37.5mph and 145N.m of rear-wheel torque, the SX-E5 outpaces traditional 50cc gas-powered bikes while staying clean, quiet, and easy to manage.

The frame is built from new-generation BIK500 lightweight high-strength steel with a 6061 aluminum alloy rear swing arm, achieving over 10% weight reduction compared to conventional steel designs. Fully adjustable front and rear suspension, hydraulic disc brakes, and an adaptable chassis geometry mean the SX-E5 grows with your rider - making it one of the most complete youth electric dirt bikes available today.

FAQ

What age and size rider is the SX-E5 designed for?

The SX-E5 is designed for riders aged 8-12 years, with an optimal rider height of 120-140cm. The adjustable seat height (24in or 26in) and adaptable rear subframe geometry allow the bike to grow with your child as their height and riding skills improve.

How far can the SX-E5 go on a single charge?

The SX-E5 delivers up to 18.64 miles of real-world range on a single charge, thanks to its 48V 1200Wh battery pack built with high-rate Samsung 50S cells. Actual range will vary based on terrain, rider weight, and riding style.

Is the SX-E5 safe to ride in wet conditions?

Yes. The battery system features multi-layer protection including waterproof sealing, thermal balance management, and shock resistance, allowing riders to confidently explore trails in wet or muddy conditions. However, full submersion in water is not recommended.

Does the SX-E5 require assembly?
