Our view: a proper 50cc-style youth electric dirt bike with serious power, app control and strong progression potential.
The RFN Warrior Youth SX-E5 is a high-performance electric dirt bike designed for young riders who are ready to progress beyond entry-level models.
With a 1200Wh lithium battery, up to 5kW peak power, hydraulic disc brakes, adjustable suspension and app-based controls, the SX-E5 delivers a serious youth motocross-style riding experience while still giving parents control over performance.
It is quiet, low-maintenance and powerful, making it an excellent alternative to a small petrol motocross bike for private land, trails and dirt tracks.
My Take as a British MX Rider
The SX-E5 is where the RFN Warrior Youth range starts to feel like a proper motocross bike rather than just a kids electric bike.
Compared with smaller bikes like a Revvi 20, Amped A24 Comp or SX-E2, the SX-E5 has a much more serious chassis, stronger power delivery and a riding position closer to a 50cc motocross machine.
If your rider is confident, around 120–140cm tall and ready for a proper youth electric dirt bike, the SX-E5 is the one to look at.

1200Wh Battery
Large lithium battery capacity for longer riding sessions and stronger performance.

Built for Serious Youth Progression
Ideal Rider Size
The SX-E5 is designed for confident young riders who need more power, better suspension and a more capable chassis than a smaller electric bike can offer.
- Recommended rider height: around 120–140cm
- Adjustable seat height: 615–665mm
- Wheelbase: 1032mm
- Approximate bike weight: 47kg
- Best suited to experienced or confident youth riders
Suitability always depends on the individual rider’s height, strength, confidence and riding experience.
Power, Speed and Control
The SX-E5 uses a powerful electric drive system with up to 5kW peak output and strong torque delivery. This gives the bike serious acceleration, climbing ability and off-road performance while remaining adjustable through selectable riding modes and app controls.
SX-E5 Performance
- Up to 5kW peak power
- Up to 145Nm torque
- Top speed up to 60km/h / 37mph
- Eco, Mid and Sport riding modes
- App-based control options
- Emergency safety lanyard power cut-off
This makes the SX-E5 exciting for capable riders while still giving parents the ability to manage performance as confidence develops.
Battery and Range
The 1200Wh lithium battery gives the SX-E5 strong riding range for private land, tracks and off-road use. The removable battery design also makes charging and battery swaps more convenient.
Suspension, Brakes and Chassis
The SX-E5 is built around a stronger youth chassis than smaller electric bikes, with proper suspension travel, hydraulic brakes and a wheel setup designed for off-road control.
Off-Road Chassis Setup
- Adjustable front and rear suspension
- Approx. 205mm front suspension travel
- Approx. 180mm rear suspension travel
- Hydraulic disc brakes front and rear
- 12” front and 10” rear wheel setup
- Stable youth motocross-style chassis
The result is a more controlled, planted feel across trails, dirt tracks, fields and rough private land.
SX-E5 vs SX-E2 — Which Should You Choose?
Choose the SX-E2 if your rider is moving up from smaller bikes and needs a manageable progression step. Choose the SX-E5 if they are confident, experienced and ready for a more serious youth electric dirt bike.
Who Is the SX-E5 Best For?
Best for Confident Youth Riders
The SX-E5 is not a basic beginner bike. It is best suited to riders who already have good bike control and are ready for stronger performance.
- Riders progressing beyond entry-level electric bikes
- Confident youth riders around 120–140cm tall
- Families looking for a quiet alternative to a 50cc petrol bike
- Private land, dirt tracks, fields and off-road riding areas
- Riders who need more range, power and suspension than the SX-E2
For complete beginners, a smaller electric bike or the SX-E2 may be the better starting point.
