Our view: the most powerful bike in the RFN Warrior Kids SX‑E range, combining stronger performance, improved suspension and larger 16-inch MX wheels for confident young off-road riders.
The new RFN Warrior SX‑E800 takes the popular children’s SX‑E platform to another level, offering more power, increased speed, a larger battery and improved off-road handling.
Designed for riders aged approximately 6 years and over and around 120–140cm tall, the SX‑E800 uses a 36V 800W electric motor producing up to 900W peak power and 50Nm of peak rear-wheel torque.
Three selectable speed settings allow performance to be introduced gradually, while 16-inch motocross wheels, front and rear hydraulic disc brakes and a Fast Ace rear shock give the SX‑E800 genuine capability across grass, dirt and uneven private land.
The SX‑E800 sits at the top of the RFN Warrior Kids range, offering a significant progression from the SX‑E500 and SX‑E700 models.
My Take as a British MX Rider
The SX‑E800 fills an important gap in the Warrior range. It retains a manageable size for younger riders but adds enough performance and chassis upgrades to feel like a proper small electric dirt bike.
The larger 36V 7.5Ah battery, 900W peak output and 16-inch MX wheels make it better suited to riders who have already developed good throttle and braking control.
The Fast Ace rear shock, stronger front brake and heavy-duty CNC alloy footrests are worthwhile upgrades for riding on rougher grass, dirt and light trails.
For a confident young rider who has outgrown the smaller Warrior models but is not yet ready for a larger youth dirt bike, the SX‑E800 looks like the natural next step.
Why Choose the RFN Warrior SX‑E800?
900W Peak Power
The most powerful model in the children’s Warrior SX‑E range, with 50Nm of peak rear-wheel torque.
Three Speed Settings
Eco, Standard and Sport modes allow parents to increase the bike’s performance as ability and confidence develop.
16-Inch MX Wheels
Larger front and rear motocross wheels provide improved stability and control across uneven off-road terrain.
Upgraded Suspension
RFN front suspension and an adjustable Fast Ace rear shock help the bike remain controlled over bumps and rough ground.
Built for Progressing Young Riders
Best for Riders Aged Approximately 6+
The RFN Warrior SX‑E800 is designed for riders approximately 120–140cm tall, with a maximum permitted rider weight of 50kg.
Its 550mm seat height, 740mm wheelbase and 20kg weight give it a more planted dirt-bike feel than the smaller SX‑E models.
The SX‑E800 is best suited to a rider who already understands throttle control, braking and basic off-road riding. It would make a strong upgrade from an electric balance bike, RFN SX‑E500, SX‑E700 or similar machine.
Age recommendations are only a guide. Suitability depends on the individual rider’s height, weight, confidence and experience, at the parent or guardian’s discretion.
Three Selectable Speed Settings
Parents can begin with Eco mode and increase the available performance gradually as the rider develops better throttle control, braking and off-road confidence.
800W Motor and Responsive Power Delivery
The 36V 800W electric motor produces up to 900W peak power and 50Nm of peak rear-wheel torque.
This gives the SX‑E800 stronger acceleration and better off-road performance than the smaller Warrior Kids models, while the selectable riding modes keep its performance manageable.
Controlled Performance
- 36V 800W electric motor
- 900W peak power
- 50Nm peak rear-wheel torque
- Three selectable speed settings
- Electronic twist-grip throttle
- Direct-drive chain transmission
- Safety lanyard power cut-off
The result is strong but controllable performance for young riders progressing onto a more capable electric dirt bike.
Upgraded Suspension, Brakes and MX Wheels
The SX‑E800 uses RFN 27mm front suspension with 50mm of stroke, paired with a Fast Ace rear shock for improved handling across grass, dirt and uneven surfaces.
Hydraulic disc brakes are fitted front and rear, with a larger 160mm front disc and 140mm rear disc providing controlled stopping performance.

- Fast Ace adjustable rear shock
- 160mm front hydraulic disc brake
