Our view: a true mini motocross-style electric bike for progressing young riders who need more power, stronger brakes and proper off-road capability.
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 greater off-road capability than the entry-level SX-E400.
Designed for riders aged around 4–8 and approximately 100–120cm tall, it combines a smooth 36V brushless motor, full suspension, hydraulic disc brakes and 14-inch all-terrain tyres.
This gives young riders a much more capable off-road experience while still retaining manageable power delivery and three selectable speed settings for controlled progression.
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 rather than simply a first electric bike.
The hydraulic brakes, full suspension and 500W peak output make it a noticeable step up from the SX-E400, but it still retains smooth power delivery and sensible speed settings for gradual progression.
It is particularly well suited to a rider who already understands basic throttle control and is ready for stronger performance, rougher terrain and a more planted riding position.
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 genuine mini motocross-style bike for riders ready to move beyond entry-level electric models.
500W Peak Output
More power and off-road capability than the SX-E400 while still retaining manageable delivery.
Hydraulic Brakes
Front and rear 140mm hydraulic disc brakes provide strong and controlled stopping performance.
Full Suspension
Front and rear suspension improve control and comfort across grass, dirt, trails and uneven terrain.
Built for Progressing Young Riders
Best for Ages 4–8
The RFN Warrior SX-E500 is designed for riders aged around 4–8 and approximately 100–120cm tall.
At 18kg, with a maximum rider weight of 50kg, it offers a stable and planted feel while remaining manageable for younger riders making the step up.
The SX-E500 is generally best suited to a rider with some previous experience, whether that has come from an electric balance bike, bicycle, entry-level electric bike or similar machine.
Suitability always depends on the individual child’s height, weight, confidence and riding ability, at the parent’s discretion.
Speed Settings
Parents can begin with the lowest setting and increase performance gradually as the rider’s throttle control, braking and confidence improve.
Smooth Power and Controlled Progression
The 36V brushless motor uses a sine-wave controller to provide smooth and predictable acceleration. This helps avoid harsh initial power delivery and makes the bike easier to control as riders develop their skills.
Built for Controlled Performance
- 36V brushless motor
- 350W rated output
- 500W peak output
- Sine-wave controller for smooth power delivery
- Twist-grip throttle
- Safety lanyard power cut-off
- Power setting lock cover for added peace of mind
This gives the SX-E500 enough performance to grow with the rider without making the power delivery unnecessarily harsh or intimidating.
Full Suspension, Hydraulic Brakes and Off-Road Tyres
Full front and rear suspension gives the SX-E500 genuine off-road capability, helping absorb bumps and uneven terrain across grass, dirt, trails and mixed surfaces.
The front and rear hydraulic disc brakes provide a noticeable improvement in stopping power and control compared with more basic braking systems.
Real Off-Road Capability
- Full front and rear suspension
- Front and rear hydraulic disc brakes
- 140mm hydraulic brake setup
- 14 x 2.4-inch all-terrain tyres
- 175mm ground clearance
- Stable 18kg chassis
The result is a machine that feels much more capable than an entry-level electric balance bike and delivers a genuine mini motocross-style riding experience.
Battery, Range and Charging
The removable and swappable battery design allows riding time to be extended with an additional charged battery.
Actual range and ride time will vary depending on rider weight, terrain, speed setting, riding style and conditions.
