Description

The RFN Warrior Pro SX-E15 is a full-size, competition-ready electric motocross bike engineered for serious riders who demand professional-grade performance without compromise. Powered by the world's first axial flux electric drive system designed for off-road motorcycles, it delivers up to 560N·m of rear-wheel torque and a blistering top speed of 55.9mph - making it a genuine contender on the track and on the trail. The aerospace-grade 6082 aluminum alloy frame is topology-optimized to be 20% lighter than traditional chromoly steel while maintaining race-level rigidity and impact endurance.

At its core is a 74V 40Ah battery pack built with Samsung 50S high-rate cells, providing up to 49.71 miles of real-world range with multi-layer protection including thermal management, shock resistance, and waterproof sealing. The control system has been refined through feedback from professional riders across 40 countries and 48 evolutionary updates, delivering silky-smooth power delivery across every terrain type. Whether you're hitting desert straights, technical climbs, or competitive MX tracks, the SX-E15 is built to perform at the limit every single time.

FAQ

What is the real-world range of the SX-E15 on a full charge?

The SX-E15 delivers up to 49.71 miles of real-world range on a full charge of its 74V 40Ah (2,960Wh) battery. Actual range will vary depending on rider weight, terrain type, speed, and riding style - aggressive track riding will reduce range while more moderate trail riding will extend it.

Is the SX-E15 suitable for adult full-size riders?

Yes - the SX-E15 is a full-size electric motocross bike designed for adult riders. The standard model has a 35-inch seat height and is recommended for riders 63 inches tall and above. The SX-E15 Plus version features a 36-inch seat height and is recommended for riders 67 inches and taller.

How does the axial flux motor differ from a standard electric motor?

The axial flux motor used in the SX-E15 is a more compact, higher power-density design compared to traditional radial flux motors. It delivers power more efficiently, runs cooler under sustained load, and generates up to 560N·m of rear-wheel torque - providing instant, linear acceleration that outperforms many gas-powered competitors in real-world off-road conditions.

Is the SX-E15 waterproof? Can I ride it in rain or mud?

The battery system features multi-layer protection including waterproof sealing, thermal balance management, and shock resistance. This means the bike is built to handle rain, mud, and wet trail conditions with confidence - the kind of conditions you'd encounter in real-world off-road and motocross use.

What warranty and return policy comes with the SX-E15?

The RFN Warrior Pro SX-E15 comes with a 2-year manufacturer warranty and RFN's 14-day risk-free trial. If you're not satisfied within the first 14 days, you can return it. RFN also provides dedicated customer service support to address any questions or issues after purchase.

Does the SX-E15 require assembly upon delivery?

The SX-E15 is a full-size motocross bike and will require some assembly upon arrival, typically including handlebar and mirror installation and minor setup. It ships with free shipping included. Given the size and weight of the bike, it is recommended to have a second person available when unboxing and assembling.
