RFN Warrior SX-E700 Review UK

Quick verdict: The RFN Warrior SX-E700 is the premium performance model in the RFN Warrior Kids range, offering a larger battery, hydraulic brakes, stronger power and a choice between MX and SM versions.

Best for: confident riders aged around 4–8 and approximately 100–120cm tall who have already mastered basic throttle and braking control and are ready for more performance than the SX-E500.

RFN Warrior SX-E700 Review

The RFN Warrior SX-E700 is the most powerful and capable model in the core RFN Warrior Kids electric dirt-bike range.

It sits above the SX-E400 and SX-E500, adding a larger 36V 7.5Ah battery, hydraulic disc brakes, stronger peak performance and a top speed of approximately 21.5mph.

The SX-E700 is also available in two distinct versions. The SX-E700 MX uses an off-road tyre setup for grass, dirt and loose terrain, while the SX-E700 SM uses a supermoto-style setup intended for smoother and firmer private riding surfaces.

Both versions share the same core electric platform, so choosing between them is mainly about where the bike will be ridden rather than which version is faster.

In this RFN Warrior SX-E700 review, we look at rider sizing, performance, speed modes, battery life, ride quality, braking, MX versus SM, strengths, drawbacks and how it compares with the SX-E500.


RFN Warrior SX-E700 Review: Our Verdict

The Premium Performance RFN Warrior

The SX-E700 is the RFN Warrior Kids model we would consider for a rider who already has the basics sorted and is genuinely ready for stronger performance.

Its larger battery, hydraulic brakes and additional peak power make it a meaningful step above the SX-E500 rather than simply a slightly faster version of the same bike.

The choice between MX and SM also allows parents to select the version that best suits the rider’s normal terrain.

Its main limitation is that it is not the right starting point for every child. Smaller, cautious or inexperienced riders will usually be better served by the SX-E400 or SX-E500. For a confident rider, however, the SX-E700 is the strongest and most complete model in the range.

Best Feature

The combination of stronger performance, a larger battery and hydraulic braking.

Best Rider

A confident and developing young rider who already understands throttle and braking control.

Main Limitation

It may be excessive for a complete beginner or a smaller rider who would be more comfortable on the SX-E500.

Overall Position

The premium performance model in the RFN Warrior Kids range.

Who Is the RFN Warrior SX-E700 For?

The RFN Warrior SX-E700 is generally designed for riders aged around 4–8 years old and approximately 100–120cm tall.

The maximum recommended rider weight is approximately 50kg, but age and weight alone do not determine whether the SX-E700 is suitable.

Because it is the most powerful model in the range, rider confidence and previous experience are especially important.

The SX-E700 is best suited to a child who already balances confidently, can use both brakes correctly, understands throttle control and has experience on a bicycle, electric balance bike, SX-E500 or another kids electric dirt bike.

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 previous 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 model

Is the SX-E700 suitable for a complete beginner?

It can technically be restricted using its lowest speed mode, but it would not normally be our first choice for a complete beginner.

The SX-E700 has stronger acceleration, a higher maximum speed and a more performance-focused setup than the smaller models.

A confident rider who is physically large enough may be able to start in Eco mode, but a cautious or inexperienced child will usually develop more comfortably on the SX-E400 or SX-E500.

Speed, range and riding time will vary according to rider weight, riding surface, terrain, temperature, speed setting and riding style.


Design and Build Quality

The SX-E700 looks and feels more like a scaled-down performance motorcycle than a traditional electric balance bike.

Its motocross-style bodywork, steel race frame, footrests, suspension and compact riding position give it a substantial and purposeful appearance.

The bike weighs approximately 20kg, which is only slightly more than the SX-E500 but still significantly heavier than a lightweight balance-bike-style model.

That additional weight helps the SX-E700 feel stable once moving, although the rider still needs enough strength and confidence to support it at a standstill.

Does the SX-E700 feel like a proper dirt bike?

Yes. Of the three core RFN Warrior Kids models, the SX-E700 delivers the most convincing miniature motorcycle experience.

The stronger performance, hydraulic brakes, suspension and riding position make it feel more substantial and capable than the smaller models.

It remains a children’s recreational electric bike, but it provides a useful introduction to the controls and riding style associated with larger motocross bikes.


Motor Performance and Riding Experience

The SX-E700 uses a 36V electric motor with up to approximately 700W of peak power and around 46Nm of peak rear-wheel torque.

Compared with the SX-E500, the difference is not limited to the higher top speed. The SX-E700 also delivers stronger performance when accelerating and riding over more demanding terrain.

This makes it more exciting for confident riders, but it also means throttle control becomes more important.

The direct-drive chain system provides a simple and responsive connection between the motor and rear wheel, while the electronic twist throttle gives the rider familiar motorcycle-style control.

For the intended rider, the SX-E700 feels lively and capable without moving into the size and performance territory of a full youth motocross bike.


Three Speed Modes Reviewed

The SX-E700 has three selectable riding modes, allowing parents to control how much performance is available.

SX-E700 speed modes

  • Eco: approximately 9.5mph
  • Standard: approximately 15.5mph
  • Sport: approximately 21.5mph

Eco mode is useful when a rider is first getting used to the size and throttle response of the bike.

Standard mode provides enough speed for most regular sessions, while Sport mode unlocks the SX-E700’s full performance for riders who have already demonstrated good control.

The selectable modes do not replace supervision or appropriate rider sizing, but they make the bike easier to introduce gradually.

Parents should not move into the higher settings until the rider can consistently accelerate smoothly, use both brakes correctly and stop within a controlled distance.


Battery Life Review

The RFN Warrior SX-E700 uses a larger 36V 7.5Ah removable lithium battery.

This is one of its most important upgrades over the SX-E500, which uses a smaller 36V 5.2Ah battery.

  • 36V 7.5Ah removable lithium battery
  • Up to approximately 15.5 miles of claimed 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 ride time depends on terrain, rider weight, speed mode, temperature and throttle use.

Riding in Sport mode on soft grass, mud or hills will use the battery more quickly than steady riding in Eco mode on firm ground.

The removable design means the battery can be charged indoors without taking the entire bike inside. It can also be stored somewhere dry and protected from extreme temperatures.


Hydraulic Braking Performance

The SX-E700 uses front and rear hydraulic disc brakes, which are a significant upgrade over the mechanical disc brakes fitted to the SX-E500.

Hydraulic brakes generally require less hand pressure and provide a more consistent lever feel.

This is particularly useful on the SX-E700 because the bike reaches higher speeds and is aimed at more confident riders.

The stronger braking system helps the bike remain controlled, but riders still need to learn how to use both brakes correctly rather than relying on one lever.

An adult should inspect the brake operation before every session and ensure that the rider can comfortably reach both levers.


Suspension and Ride Quality

The SX-E700 uses front and rear suspension to improve control and comfort across uneven riding surfaces.

The RFN spring fork provides approximately 85mm of stroke, giving the front wheel useful movement when crossing bumps, grass and rougher terrain.

The suspension contributes to the SX-E700’s more substantial dirt-bike feel and helps keep the tyres in contact with the ground.

It is designed for recreational off-road riding and developing young riders rather than unrestricted jumping or full competition motocross use.

For normal private-track, field and garden riding, however, it provides a capable and confidence-inspiring platform.


RFN Warrior SX-E700 MX vs SX-E700 SM

The MX and SM use the same motor, battery, speed modes and core performance platform.

The main difference is the tyre setup and the type of riding surface each model suits.

Feature SX-E700 MX SX-E700 SM
Tyre Style Off-road motocross-style tyres Smoother supermoto-style tyres
Best Terrain Grass, dirt, fields and loose terrain Smooth, firm and prepared private surfaces
Best For General off-road riding Supermoto-style riding and firm surfaces
Versatility Usually the most versatile choice More specialised surface choice

For most families riding in gardens, fields, paddocks or dirt areas, the SX-E700 MX will normally be the more versatile choice.

The SX-E700 SM is better for riders who specifically want the supermoto appearance and will mainly use the bike on smooth, firm private surfaces.

Read our complete RFN Warrior SX-E700 MX vs SX-E700 SM comparison before choosing.


How Does the SX-E700 Ride Off Road?

The SX-E700 MX is the version designed for loose and uneven private off-road terrain.

Its tyre setup, suspension and stronger motor allow it to cope with:

  • Grass fields
  • Dirt tracks
  • Private paddocks
  • Light woodland trails
  • Uneven garden terrain
  • Beginner motocross-style practice areas

The additional battery capacity also makes it better suited to longer sessions than the smaller RFN Warrior models.

The SM version is less suitable for mud and soft ground because its smoother tyres are designed around firm surfaces rather than loose-terrain grip.


RFN Warrior SX-E500 vs SX-E700

The SX-E500 and SX-E700 may suit a similar physical rider size, but they are aimed at 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 700W peak power
Top Speed Approximately 18.5mph Approximately 21.5mph
Battery 36V 5.2Ah 36V 7.5Ah
Brakes Mechanical disc brakes Hydraulic disc brakes
Range Up to approximately 11 miles Up to approximately 15.5 miles

Choose the SX-E500 when manageable all-round performance is the priority.

Choose the SX-E700 when the rider is already confident and will benefit from the stronger acceleration, longer range and hydraulic brakes.

What Could Be Better?

No bike is perfect, and there are several points worth considering before choosing the SX-E700.

  • It may offer too much performance for a complete beginner.
  • The physical age and height range overlaps with the SX-E500, so rider ability matters more than simply buying the higher model.
  • The SM version is less versatile on loose or muddy ground.
  • At approximately 20kg, smaller riders may struggle to lift or manoeuvre the bike.
  • The higher maximum speed requires a suitable riding area and close supervision.
  • It costs more than the SX-E500 because of the battery, brakes and performance upgrades.

These are not faults with the bike. They are reasons to make sure the SX-E700 genuinely matches the rider rather than automatically selecting the most powerful model.


Would We Recommend the SX-E700?

Yes — For a Confident Rider

The SX-E700 is the strongest choice in the RFN Warrior Kids range for riders who have already developed good bike control.

It offers meaningful upgrades over the SX-E500, including a larger battery, stronger peak performance and front and rear hydraulic brakes.

For most off-road customers, we would choose the MX version because it is more versatile across grass, dirt and mixed terrain.

Is the RFN Warrior SX-E700 Worth Buying?

The RFN Warrior SX-E700 is worth buying if the rider is genuinely ready for the highest-performing model in the RFN Warrior Kids range.

Its biggest strengths are the larger battery, hydraulic brakes, three adjustable riding modes and choice between MX and SM setups.

It offers more range, stronger performance and more advanced braking than the SX-E500, making it better suited to confident riders who use the bike regularly.

It is not automatically the best choice simply because it is the highest model. A developing rider may progress more comfortably on the SX-E500, while the SX-E700 makes the most sense once the rider has the confidence and skill to use its upgrades.


My Take as a British Motocross Rider

The SX-E700 is the RFN Warrior model I would look at when a rider has already mastered the basics and genuinely wants the next step.

The hydraulic brakes are an important upgrade because they match the bike’s additional speed and performance, while the larger battery is useful for longer riding sessions.

For most families, I would choose the MX version. It is more versatile and better suited to the grass, dirt and mixed off-road ground where these bikes are usually ridden.

For a confident child who has progressed beyond smaller electric bikes, the SX-E700 is a strong premium option and the most complete bike in the core RFN Warrior Kids range.
