Meet the RFN Warrior SX-E700 R SM Electric Supermoto Bike – a high-performance kids electric bike specifically developed for riders who want speed, control and Supermoto-style performance on smooth, hard surfaces.

Sitting at the top end of the RFN Warrior kids range, the SX-E700 R SM features a 36V 500W electric motor producing up to 700W peak power and 46Nm of peak rear-wheel torque, combined with a larger 36V 7.5Ah lithium battery.

With three selectable speed modes, a top speed of up to 21.5mph, front and rear hydraulic disc brakes, upgraded Fast Ace rear suspension and 14-inch Supermoto wheels and tyres, the SX-E700 R SM delivers serious performance in a compact package designed for young riders.

Unlike the MX version, the SM – Supermoto – Edition is specifically designed for smoother, hard-surface track riding, giving riders a fast-rolling and responsive setup for indoor and outdoor Supermoto-style racing.

⚡ 500W Motor with 700W Peak Power

At the heart of the RFN Warrior SX-E700 R SM is a 36V 500W electric motor, capable of producing an impressive 700W peak power.

With up to 46Nm of peak rear-wheel torque, the E700 R delivers strong acceleration and responsive electric performance.

Compared with the standard SX-E Warrior models, the E700 R brings a significant step up in performance, battery capacity and overall capability.

With simple electric power delivery, there's no clutch or conventional gearbox to worry about, allowing young riders to concentrate on:

  • Throttle control
  • Braking
  • Cornering
  • Balance
  • Body positioning
  • Developing proper riding technique

🏁 Three Speed Modes – Up to 21.5mph

The SX-E700 R SM features three selectable riding modes, allowing performance to be increased as the rider's confidence and ability develop.

ECO Mode – 9.5mph

A more controlled setting that's ideal for getting accustomed to the bike and developing throttle control.

STD Mode – 15.5mph

Provides increased speed and performance as the rider's confidence improves.

SPORT Mode – 21.5mph

Unlocks the full performance of the SX-E700 R SM for experienced and confident riders.

This progressive system means young riders don't need immediate access to maximum performance and can develop their skills before moving through the speed settings.

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

🔋 36V 7.5Ah Lithium Battery

The E700 R receives a larger 36V 7.5Ah lithium battery, giving it considerably more riding capacity than the lower-powered Warrior models.

In ECO mode, RFN quotes a range of up to approximately:

15.5 miles / around 1 hour of riding

The battery takes approximately 2.5 hours to charge from 0–100%.

Battery & Performance

  • Battery: 36V 7.5Ah Lithium
  • Motor: 36V 500W
  • Peak Power: 700W
  • Peak Rear-Wheel Torque: 46Nm
  • Maximum Speed: 21.5mph
  • Maximum Range: Up to 15.5 miles in ECO Mode
  • Approximate ECO Runtime: Up to 1 Hour
  • Charge Time: Approx. 2.5 Hours

Actual range and riding time will vary depending on rider weight, speed setting, riding style and conditions.

🏎️ Supermoto Wheels & Tyres

The SM version of the SX-E700 R has been specifically designed for Supermoto-style riding.

Instead of the knobbly off-road tyres found on the MX version, the SM uses 14-inch Supermoto tyres, designed to perform on smoother, harder surfaces.

This provides a fast-rolling, responsive riding experience that's perfect for suitable indoor and outdoor Supermoto tracks.

SM or MX – Which Should You Choose?

Choose the SX-E700 R SM if the rider will primarily use the bike on smooth, hard-surface Supermoto-style tracks.

For grass, dirt, mud and traditional off-road riding, the SX-E700 R MX with its off-road tyres is the more suitable option.

🔧 Upgraded Fast Ace Rear Suspension

The SX-E700 R isn't simply about adding more motor power.

RFN has upgraded the chassis to match the increased performance.

At the front, the bike uses RFN spring suspension with 85mm stroke.

At the rear, a premium Fast Ace shock with adjustable damping allows the suspension to be better matched to the rider and riding conditions.

This upgraded suspension package helps keep the bike stable and controlled as speeds increase.

🛑 Front & Rear Hydraulic Disc Brakes

More speed requires better stopping power.

The RFN Warrior SX-E700 R SM features 140mm hydraulic disc brakes at both the front and rear.

The hydraulic braking system provides strong, progressive stopping performance and gives developing riders improved control compared with more basic braking systems.

💪 Heavy-Duty CNC Alloy Footrests

The E700 R also receives CNC heavy-duty alloy footrests, providing a strong and secure platform for the rider.

Combined with the higher handlebar setup and handlebar pad, these upgrades help give the SX-E700 R a proper mini-motorcycle riding position.

🛡️ Lanyard Power-Off Safety System

RFN has incorporated a lanyard Power Off system as an additional safety feature.

The lanyard system can cut power to the bike, providing an additional layer of protection for younger riders.

Combined with the three selectable speed modes and powerful hydraulic brakes, this gives parents greater control over how the rider progresses through the bike's performance.

💡 LED Side Light

The E700 R Special Edition also features a distinctive LED side light, adding another visual upgrade and helping distinguish the E700 R from the standard Warrior models.

👦 Who Is the RFN Warrior SX-E700 R SM For?

RFN recommends the SX-E700 R SM for riders approximately:

4–8 years old / 100–120cm tall

The maximum rider weight is 50kg.

However, age should always be treated as a guide.

When choosing the correct electric bike, parents should consider:

  • Rider height
  • Rider weight
  • Previous riding experience
  • Confidence
  • Coordination
  • Ability
  • Intended riding surface

With a 490mm seat height, the SX-E700 R provides a compact riding position while offering considerably more performance than an entry-level electric kids bike.

Children should be supervised by a responsible adult and appropriate protective equipment, including a suitable helmet, should always be worn.
