Quick answer: The RFN Warrior SX-E700 is the highest-performance electric bike in the core RFN Warrior Kids range, offering up to 700W peak power, hydraulic brakes, a larger removable battery and a choice of MX or SM versions.
Best for: confident riders aged around 4–8 and approximately 100–120cm tall who are ready for more power, stronger braking and longer riding sessions than the SX-E500 provides.
RFN Warrior SX-E700 Electric Bike UK
The RFN Warrior SX-E700 electric bike is the premium performance model in the RFN Warrior Kids range.
It sits above the SX-E400 and SX-E500, adding a larger 36V 7.5Ah battery, hydraulic disc brakes, up to 700W of peak power and a maximum speed of approximately 21.5mph.
The SX-E700 is available in two versions. The SX-E700 MX uses an off-road tyre setup designed for grass, dirt and loose terrain, while the SX-E700 SM uses smoother supermoto-style tyres for firm and prepared private riding surfaces.
Both versions share the same core motor, battery and three-speed platform, so the main buying decision is based on the terrain where the bike will normally be ridden.
At Garland Powersports, we stock the RFN Warrior SX-E700 range with fast UK delivery, specialist rider-sizing guidance and clear advice choosing between the MX and SM versions.
What Is the RFN Warrior SX-E700?
The RFN Warrior SX-E700 is a youth electric dirt bike designed for confident young riders who want more performance and stronger components than the smaller RFN Warrior models provide.
It uses a motorcycle-style riding position with proper footrests, an electronic twist throttle, front and rear suspension and hydraulic disc brakes.
The SX-E700 is not simply a faster SX-E500. Its larger battery, stronger peak performance and upgraded braking system make it a meaningful step up within the range.
It is intended for recreational use on private land and suitable off-road or prepared riding areas with the landowner’s permission.
Why Choose the RFN Warrior SX-E700?
The SX-E700 is designed for riders who have already developed good throttle and braking control and are ready for a more capable electric bike.
It combines increased performance with three adjustable riding modes, allowing parents to introduce the available speed gradually.
700W Peak Power
The strongest performance available in the core RFN Warrior Kids range.
Hydraulic Brakes
Front and rear hydraulic disc brakes provide stronger and more consistent stopping performance.
Larger Battery
The removable 36V 7.5Ah battery offers more capacity and range than the SX-E500 battery.
MX or SM Choice
Choose off-road MX tyres or smoother supermoto-style SM tyres to suit the rider’s terrain.
Who Is the RFN Warrior SX-E700 For?
The RFN Warrior SX-E700 is generally recommended for riders aged around 4–8 years old and approximately 100–120cm tall.
These figures should only be treated as a starting point. The SX-E700 is the fastest and most capable model in the range, so rider confidence and previous experience are especially important.
It is best suited to a rider who already balances confidently, understands twist-throttle control and can use both brakes correctly.
A smaller, cautious or inexperienced child may be better suited to the SX-E400 or SX-E500, even if their age falls within the SX-E700 guide.
RFN Warrior SX-E700 rider guide
- Age guide: around 4–8 years
- Height guide: approximately 100–120cm
- Maximum rider weight: approximately 50kg
- Best rider type: confident or experienced young rider
- Useful experience: SX-E500, bicycle, electric balance bike or another electric dirt bike
- MX terrain: grass, dirt, fields and loose off-road surfaces
- SM terrain: smooth, firm and prepared private surfaces
- Position in the range: premium performance RFN Warrior model
Is the SX-E700 suitable as a first electric bike?
It can be restricted using its lowest speed setting, but it would not normally be our first recommendation for a complete beginner.
The SX-E700 weighs approximately 20kg and reaches around 21.5mph in Sport mode. The rider should already understand basic bike control and be physically capable of supporting the bike.
A developing rider will often progress more comfortably on the SX-E500 before moving onto the SX-E700.

Three Adjustable Speed Modes
The SX-E700 has three selectable speed settings, helping parents introduce the bike’s performance gradually.
Although this is the most powerful model in the range, the rider does not need immediate access to its full speed.
Performance for Developing Riders
- Eco: approximately 9.5mph
- Standard: approximately 15.5mph
- Sport: approximately 21.5mph
Eco mode allows the rider to become familiar with the bike’s size, throttle and hydraulic brakes.
Standard mode provides useful performance for regular riding, while Sport mode should only be unlocked once the rider consistently demonstrates safe control.
Shop RFN Warrior SX-E700Motor and Performance
The RFN Warrior SX-E700 uses a 36V 500W motor capable of producing up to approximately 700W of peak power.
It delivers stronger acceleration and higher maximum performance than the SX-E500, making it better suited to confident riders.
The claimed peak rear-wheel torque of approximately 46Nm helps the bike perform across grass, dirt and light inclines.
The electronic twist throttle gives the rider motorcycle-style control, while the direct-drive chain system provides a simple and responsive power connection to the rear wheel.
The electric platform remains quiet and avoids the fuel, heat and engine maintenance associated with a small petrol dirt bike.
Battery, Range and Charging
The SX-E700 uses a removable 36V 7.5Ah lithium battery.
This larger battery is one of the main upgrades over the SX-E500’s 36V 5.2Ah setup.
- 36V 7.5Ah lithium battery
- Removable battery pack
- Up to approximately 15.5 miles of claimed Eco range
- Around one hour of riding under suitable conditions
- Approximately 2.5 hours for a full charge
- More battery capacity than the SX-E500
Actual riding time depends on speed mode, rider weight, terrain, temperature and throttle use.
Sport-mode riding on hills, soft grass or mud will reduce battery life compared with steady Eco-mode riding on firm and level ground.
The removable battery can be charged indoors and stored somewhere dry and protected from extreme temperatures.
Hydraulic Disc Brakes
The SX-E700 is equipped with front and rear hydraulic disc brakes.
This is a significant upgrade over the mechanical braking system used on the SX-E500.
Hydraulic brakes usually require less hand pressure and provide a more consistent braking feel, which is particularly useful as the bike reaches higher speeds.
They give the rider separate control over the front and rear wheel and help the bike remain predictable during faster riding sessions.
An adult should inspect both brakes before every ride and ensure the rider can comfortably reach and operate the levers.
Front and Rear Suspension
The SX-E700 has front and rear suspension designed to improve control across uneven riding surfaces.
The RFN spring fork provides approximately 85mm of movement, helping the front wheel absorb bumps and maintain contact with the ground.
The rear shock supports the bike over rough grass, dirt tracks and other light off-road terrain.
This setup gives the SX-E700 a more substantial motorcycle feel than an electric balance bike, although it remains designed for recreational riding rather than unrestricted motocross jumping.
RFN Warrior SX-E700 MX vs SM
The SX-E700 is available in MX and SM versions. Both share the same core motor, battery, speed modes and braking platform.
The main difference is the tyre setup and the terrain each version is designed to suit.
| Feature | SX-E700 MX | SX-E700 SM |
|---|---|---|
| Tyre Style | Off-road motocross tyres | Smoother supermoto-style tyres |
| Best Terrain | Grass, dirt, fields and loose terrain | Smooth, hard and prepared private surfaces |
| Best For | General private off-road riding | Supermoto-style riding on firm ground |
| Versatility | Usually the most versatile option | More specialised surface choice |
For most riders using the bike on grass, dirt, paddocks or mixed private terrain, the SX-E700 MX will normally be the better all-round choice.
The SX-E700 SM makes more sense for riders who prefer the supermoto appearance and will mainly use the bike on smooth, firm surfaces.
Read our full RFN Warrior SX-E700 MX vs SX-E700 SM comparison before deciding.
Where Can the RFN Warrior SX-E700 Be Ridden?
The SX-E700 is intended for use on private land and suitable designated riding areas with the landowner’s permission.
The MX version is suitable for:
- Private gardens with sufficient space
- Grass fields
- Private paddocks
- Dirt tracks
- Light woodland trails
- Beginner motocross-style practice areas
The SM version is better suited to smooth and firm private surfaces where its road-style tyres can work correctly.
Neither version is road legal and neither should be ridden on public roads, pavements or cycle paths.
RFN Warrior SX-E500 vs SX-E700
The SX-E500 and SX-E700 may suit a similar physical rider size, but they are designed for different confidence and experience levels.
| Feature | SX-E500 | SX-E700 |
|---|---|---|
| Best For | Confident beginner or developing rider | Confident and more experienced rider |
| Performance | 500W rated output | Up to approximately 700W peak power |
| Maximum Speed | Approximately 18.5mph | Approximately 21.5mph |
| Battery | 36V 5.2Ah | 36V 7.5Ah |
| Claimed Range | Up to approximately 11 miles | Up to approximately 15.5 miles |
| Brakes | Mechanical disc brakes | Hydraulic disc brakes |
Choose the SX-E500 when manageable performance and rider development remain the priorities.
Choose the SX-E700 when the rider already has good control and will benefit from stronger power, longer range and hydraulic braking.

How Does the SX-E700 Compare With an Electric Balance Bike?
The SX-E700 offers a completely different riding experience from a traditional electric balance bike.
An electric balance bike is usually lighter and focused on simple balance development. The SX-E700 is a more substantial electric motorcycle-style platform aimed at confident riders.
| Electric Balance Bike | RFN Warrior SX-E700 |
|---|---|
| Usually lighter and simpler | More substantial performance-focused chassis |
| Bicycle-style riding position | Motorcycle-style position with proper footrests |
| Best for early balance development | Best for advanced throttle, braking and off-road progression |
| Often suitable for complete beginners | Designed for confident or experienced young riders |
Is the RFN Warrior SX-E700 Worth Buying?
The RFN Warrior SX-E700 is worth considering for a confident rider who has progressed beyond the capabilities of a smaller electric bike.
Its strongest features are the larger battery, hydraulic disc brakes, three adjustable riding modes and choice between MX and SM tyre setups.
It offers a meaningful upgrade over the SX-E500 rather than simply providing a small increase in top speed.
It is not automatically the correct choice because it is the highest model. The rider should have enough confidence and experience to use the additional performance safely.
For the correct rider, the SX-E700 is the premium and most complete option in the RFN Warrior Kids range.

My Take as a British Motocross Rider
The SX-E700 is the RFN Warrior model I would look at once a rider has already developed good throttle and braking control.
The hydraulic brakes are a meaningful upgrade because they match the additional performance, while the larger battery makes the bike better suited to longer riding sessions.
For most customers, I would choose the MX version because it offers more versatility across grass, dirt and mixed off-road terrain.
For a confident rider who is ready to move beyond the SX-E500, the SX-E700 is the premium and most capable choice in the range.
