About the RFN Warrior SX-E400 400W Kids Electric Dirt Bike
Introduce your young rider to the excitement of off-road riding with the RFN Warrior SX-E400 Kids Electric Dirt Bike – a compact electric motocross-style bike designed specifically for younger riders taking their first steps into powered two-wheel riding.
Powered by a 36V 250W electric motor producing up to 400W peak power and 26Nm of peak rear-wheel torque , the SX-E400 combines manageable performance with genuine dirt-bike styling and a proper footpeg riding position.
With three selectable speed modes from 5mph to 15.5mph , a 36V 5.2Ah lithium battery , front and rear suspension, 12-inch wheels and a rear disc brake, the SX-E400 gives young riders a bike they can develop their confidence and skills on rather than immediately outgrow.
RFN recommends the SX-E400 for riders approximately 3–6 years old or 90–110cm tall , making it the smallest and most accessible model in the RFN Warrior Kids range.
⚡ 250W Motor with 400W Peak Power
At the heart of the RFN Warrior SX-E400 is a 36V 250W electric motor , delivering up to 400W peak power .
More importantly, the SX-E400 produces up to 26Nm of peak torque at the rear wheel , providing responsive acceleration while retaining manageable performance for younger riders.
The simple electronic twist throttle and direct-drive chain system mean there's no clutch or conventional gearbox to master.
Young riders can concentrate on developing the skills that matter:
• Throttle control
• Balance and coordination
• Braking
• Cornering
• Body positioning
• Confidence on two wheels
• Basic off-road riding technique
For children with an interest in motocross or dirt bikes, the SX-E400 provides an exciting introduction to a proper footpeg-style electric bike.
🏁 3 Selectable Speed Modes
One of the SX-E400's most important features is its three selectable speed settings .
Rather than giving a young rider immediate access to the bike's maximum performance, parents can start them at a much more manageable speed and increase the performance as their confidence and ability develop.
ECO Mode – 5mph
The lowest setting is ideal for introducing a young rider to the bike and allowing them to become comfortable with the throttle, brakes and riding position.
STD Mode – 7.5mph
Once their control and confidence improve, Standard Mode provides a useful step up in performance.
