The RFN Warrior SX-E500 is a serious step-up electric MX-style bike for young riders who are ready for more power, more control and more off-road capability than the entry-level SX-E400.
With a smooth 36V brushless motor, full dual suspension, hydraulic disc brakes and 14” all-terrain tyres, it gives young riders a much more capable off-road riding experience while still staying manageable and confidence-building.
The SX-E500 sits in the middle of the RFN Warrior Kids range, above the SX-E400 and below the higher-performance SX-E700.

My Take as a British MX Rider
The SX-E500 is where the RFN Warrior range starts to feel like a more serious mini motocross-style bike.
The hydraulic brakes, dual suspension and 500W peak output make it a noticeable step up from the SX-E400, but it still keeps smooth power delivery and sensible speed modes for progression.
For a young rider who has outgrown an entry-level electric bike and wants a proper step-up MX-style machine, the SX-E500 is a strong choice.

Why Choose the RFN Warrior SX-E500?
Step-Up MX Feel
A true mini motocross-style bike for riders ready to move beyond entry-level models.
500W Peak Output
More power and capability than the SX-E400 while still staying manageable.
Hydraulic Brakes
Front and rear 140mm hydraulic disc brakes offer stronger, more controlled stopping power.
Dual Suspension
Full dual suspension gives better control across grass, trails and rougher surfaces.
Built for Progressing Young Riders
Best for Ages 4–8
The RFN Warrior SX-E500 is designed for riders aged around 4–8, approximately 100–120cm tall.
At 18kg, with a maximum rider weight of 50kg, it offers a stable and planted feel while still being manageable for younger riders stepping up.
Suitability always depends on the individual child’s height, weight and skill level — at the parent’s discretion.
Speed Settings
Smooth Power and Progression
The 36V brushless motor uses a sine wave controller to deliver smooth, predictable power. This removes harsh acceleration and makes the bike easier to control as riders build confidence.
Built for Controlled Performance
- 36V brushless motor
- 350W rated output, 500W peak
- Sine wave controller for smoother power delivery
- Twist grip throttle
- Safety lanyard power-off
- Power lock cover for extra peace of mind
This gives the SX-E500 enough performance to grow with your rider without feeling harsh or intimidating.
Suspension, Tyres and Braking
Full dual suspension gives the SX-E500 genuine off-road capability, helping absorb bumps and uneven terrain across grass, trails and mixed surfaces.
Real Off-Road Capability
- Full dual suspension
- Front and rear hydraulic disc brakes
- 140mm hydraulic brake setup
- 14 x 2.4 inch all-terrain tyres
- 175mm ground clearance
It feels much more capable than an entry-level electric balance bike and gives riders a genuine mini motocross experience.
