Give young riders the perfect introduction to electric off-road riding with the RFN Warrior SX-E500 Kids Electric Dirt Bike – a compact, capable and confidence-inspiring electric bike designed specifically for younger riders.

Powered by a 36V 350W brushless electric motor with 500W rated output and 34Nm of torque, the SX-E500 delivers smooth, predictable acceleration that's ideal for developing throttle control and riding confidence.

With three selectable speed settings up to 18.5mph, a 36V 5.2Ah lithium battery, 14-inch wheels, front and rear disc brakes and suspension at both ends, the RFN Warrior SX-E500 combines genuine dirt-bike styling with electric performance that's easy for young riders to enjoy.

Designed for riders approximately 100–120cm tall and up to 50kg, it's an excellent step into the world of electric motocross and off-road riding.

⚡ 500W Rated Electric Performance

At the heart of the RFN Warrior SX-E500 is a 36V 350W brushless electric motor, delivering a 500W rated output and an impressive 34Nm of torque.

The smooth electric power delivery makes the SX-E500 easy to ride while still providing plenty of performance as a child's confidence develops.

Unlike a conventional petrol-powered dirt bike, there's no clutch or gearbox to master. Young riders can concentrate on developing the skills that matter:

• Throttle control

• Balance and coordination

• Braking

• Cornering

• Body positioning

• Line choice

• Overall bike control

This makes the SX-E500 an excellent platform for children beginning their off-road riding journey.

🏁 Three Speed Modes – Up to 18.5mph

The RFN Warrior SX-E500 features three selectable speed settings, allowing the bike's performance to progress alongside the rider.

ECO Mode – 9.5mph

A more manageable setting that's ideal for riders learning how the bike responds and developing their throttle control.

STD Mode – 13.5mph

Provides increased performance once the rider has developed greater confidence and control.

SPORT Mode – 18.5mph

Unlocks the SX-E500's maximum performance for more confident and experienced young riders.

Having three riding modes allows parents to introduce performance progressively rather than giving the rider access to maximum speed immediately.

Maximum speed can vary depending on rider weight, terrain, battery charge and riding conditions.

🔋 36V 5.2Ah Lithium-Ion Battery

The SX-E500 is powered by a 36V 5.2Ah lithium-ion battery with approximately 187Wh of energy capacity.

RFN quotes a maximum range of up to 11 miles, with approximately one hour of riding in ECO mode.

• Maximum Range: Up to 11 Miles

• ECO Runtime: Approx. 1 Hour

🏍️ Built for Young Off-Road Riders

The SX-E500 is a proper kids electric dirt bike rather than simply a powered toy.

Its compact chassis, dirt-bike riding position and electric powertrain give young riders the opportunity to develop genuine riding skills from an early age.

Wide tyres provide grip across suitable surfaces such as:

• Grass

• Dirt

• Fields

• Light trails

• Suitable off-road tracks

• Private land

For children interested in motocross or off-road riding, the SX-E500 provides an exciting introduction without the noise and complexity of a conventional petrol engine.

🔧 Front & Rear Suspension

Off-road riding demands a bike capable of handling bumps and uneven ground.

The SX-E500 features suspension at both the front and rear to improve rider comfort and help maintain control across rough surfaces.

At the rear, a mono-shock suspension system helps keep the bike composed over bumps and uneven terrain.

With approximately 175mm of ground clearance, the SX-E500 is designed to provide useful clearance for suitable off-road riding.

🛑 Front & Rear 140mm Disc Brakes

Reliable stopping performance is essential as young riders develop their speed and confidence.

The RFN Warrior SX-E500 features 140mm disc brakes at both the front and rear, providing consistent and predictable braking.

This allows young riders to develop proper front and rear braking technique while maintaining control of the bike.

🛞 14" Front & Rear Wheels

The SX-E500 runs on 14-inch front and rear wheels, providing an excellent balance between manoeuvrability and stability for younger riders.

The wheel size works particularly well with the SX-E500's compact dimensions, making the bike manageable while still providing a proper dirt-bike riding position.

🛡️ Rider Safety Features

RFN has equipped the SX-E500 with useful safety features designed specifically for younger riders.

Lanyard Power-Off System

A lanyard-style power-off switch cuts power if the rider becomes separated from the bike.

Power-Lock Cover

A secure power-button cover helps prevent unintended operation of the bike.

Combined with the selectable speed modes, these features give parents greater control over how a young rider is introduced to electric riding.

🪶 Manageable 19kg Weight

The RFN Warrior SX-E500 weighs approximately 19kg, making it substantial enough to provide a stable dirt-bike feel while remaining manageable for younger riders.

The bike has a maximum recommended rider weight of 50kg.
