Looking for the best place to buy the RFN Warrior SX-E500 in the UK? At Garland Powersports, we stock the RFN Warrior Kids range with fast UK delivery, clear sizing advice and specialist support to help parents choose the correct bike.
The RFN Warrior SX-E500 is one of the strongest all-round options in the RFN Kids range.

Why Buy the RFN Warrior SX-E500 From Garland Powersports?

The SX-E500 is often bought by parents moving their child on from a smaller balance bike, bicycle or entry-level electric bike. Choosing the correct model matters because the SX-E400, SX-E500 and SX-E700 may look similar, but they suit different rider sizes and confidence levels.

Who Is the RFN Warrior SX-E500 Best For?
The RFN Warrior SX-E500 is designed for riders aged around 4–7 years old and approximately 100–120cm tall.
Age and height should always be treated as a guide. The correct bike will also depend on the rider’s inside leg measurement, strength, confidence and previous experience on two wheels.
The SX-E500 is particularly well suited to children who have already mastered a balance bike, bicycle or smaller electric bike and now want something with a more substantial chassis, larger wheels and stronger performance.
It can also work as a first electric dirt bike for a confident rider who is tall enough to comfortably manage the bike and understands basic throttle and braking control.

Why Choose the RFN Warrior SX-E500?
The SX-E500 is positioned in the middle of the RFN Warrior Kids range. For many families, that makes it the most versatile all-round choice.
It offers more size and performance than the SX-E400 but remains less powerful and demanding than the SX-E700. This gives riders room to develop without immediately placing them on the biggest bike in the range.
- Strong all-round option for growing riders
- Proper electric motocross-style design
- 14-inch front and rear wheels
- Front and rear suspension
- Three selectable speed settings
- Top speed of approximately 18.5mph
- Removable 36V lithium battery
- Front and rear disc brakes
- Quiet brushless electric motor
- Lanyard-style safety power-off switch
- Suitable for grass, dirt and light off-road riding
The larger 14-inch wheels help the bike feel more stable across uneven surfaces, while the selectable riding modes allow parents to control how much performance is available.

Is the SX-E500 the Best All-Round RFN Warrior?
For many riders, the SX-E500 is the sweet spot in the RFN Warrior Kids range.
It provides more room to grow than the SX-E400 without immediately moving the rider onto the additional size and performance of the SX-E700. This makes it a sensible option for families who want a bike that feels exciting now but will not be outgrown too quickly.
Best All-Round RFN Warrior
The SX-E500 is usually the model we would consider for a rider who has moved beyond a small balance bike but is not yet ready for the strongest RFN Kids bike.
- More room to grow than the SX-E400
- Less intimidating than moving straight onto the SX-E700
- Three speed settings for gradual progression
- 14-inch wheels for improved stability
- Proper suspension and disc brakes
- Motocross styling that feels like a genuine dirt bike
RFN Warrior SX-E400 vs SX-E500 vs SX-E700
If you're deciding between the three RFN Warrior Kids models, the right choice usually comes down to the rider's height, confidence and previous riding experience rather than simply choosing the fastest bike.
The SX-E400 is designed for the youngest riders, the SX-E500 is the all-round model that suits most children, while the SX-E700 is aimed at taller or more experienced riders who are ready for additional performance.
| Model | Best For | Rider Type | Shop |
|---|---|---|---|
| RFN Warrior SX-E400 | Smaller and younger riders | First electric dirt bike | Shop SX-E400 |
| RFN Warrior SX-E500 | Growing riders wanting the best all-round option | Confident beginner to intermediate rider | Shop SX-E500 |
| RFN Warrior SX-E700 | Older, taller and more confident riders | Experienced young rider | Shop SX-E700 |
The SX-E400 is usually the best option for the youngest riders starting out. The SX-E500 bridges the gap perfectly, offering noticeably more size and capability without becoming intimidating. The SX-E700 then becomes the natural progression once the rider has outgrown the SX-E500.

Three Speed Modes That Grow With Your Rider
One of the biggest advantages of the RFN Warrior SX-E500 is its three selectable riding modes.
Rather than giving a new rider access to the bike's maximum performance immediately, parents can gradually increase the available speed as confidence and ability improve.
Three riding modes
- Mode 1: approximately 9.5mph
- Mode 2: approximately 13.5mph
- Mode 3: approximately 18.5mph
This progressive setup makes the SX-E500 suitable for riders who are still learning while giving them room to improve over time.
Many parents leave the bike in the lower settings for the first few rides before unlocking the higher modes once throttle control and braking become second nature.
Battery, Range and Charging
The SX-E500 uses a removable 36V 5.2Ah lithium-ion battery, making charging much easier than bikes with permanently fitted batteries.
Instead of taking the entire bike indoors, the battery can simply be removed and charged separately.
- 36V 5.2Ah lithium battery
- Removable battery pack
- Up to approximately 11 miles of riding
- Up to around 2½ hours charging time
- Quiet, maintenance-friendly electric power
Actual range depends on rider weight, terrain, speed setting, temperature and how aggressively the bike is ridden. Riding on grass, mud or steep hills will naturally reduce riding time compared with smooth flat ground.
Built Like a Proper Mini Dirt Bike
Unlike many children's electric bikes that are based around a balance bike chassis, the SX-E500 has been designed to feel like a genuine miniature motocross bike.
The aluminium frame, front suspension forks and rear mono shock give the bike a far more planted feel over uneven ground.
The larger 14-inch wheels also help improve stability while riding across rough grass, woodland tracks and private motocross practice areas.
This is one of the reasons many families choose the SX-E500 over smaller balance-bike-style electric bikes once their child has developed enough confidence.
Front & Rear Disc Brakes
The RFN Warrior SX-E500 is fitted with front and rear mechanical disc brakes, giving riders much better stopping performance than simple rear-only braking systems.
Learning to use both brakes correctly is an important stepping stone towards riding larger motocross bikes in the future.
Parents should always check brake operation before every ride and ensure the rider understands how to stop safely before increasing the speed setting.
Who Should Buy the SX-E500?
The SX-E500 is ideal for children who have already mastered riding on two wheels and are ready for something that feels much more like a real dirt bike.
It particularly suits riders who:
- Have outgrown a balance bike
- Already ride a bicycle confidently
- Need more room than the SX-E400 offers
- Want a proper motocross-style riding position
- Need a bike that can grow with them over several years
If your child is very small, very cautious or completely new to riding, the SX-E400 may still be the better starting point.
If they're already tall, experienced and looking for more speed and performance, the SX-E700 will usually make more sense.
Why the SX-E500 Is My Pick for Most Riders
The Sweet Spot
If I had to recommend just one bike from the RFN Warrior Kids range to the majority of families, it would normally be the SX-E500.
It sits right in the middle of the range, giving younger riders enough performance to stay exciting without becoming overwhelming.
Because of that, most children get plenty of use from the SX-E500 before needing to move up to the SX-E700.

Is the RFN Warrior SX-E500 Worth Buying?
The RFN Warrior SX-E500 is worth buying if your child has moved beyond a small balance bike and wants something that feels much more like a proper electric dirt bike.
Its main strengths are the larger 14-inch wheels, front and rear suspension, three speed settings and removable battery. Together, these features give the bike more room for progression than a smaller entry-level model.
It is particularly good value for families who want one bike that can cover the step between a small first electric bike and the larger SX-E700.
The SX-E500 may not be the right choice for every rider. A very small or cautious child may be better suited to the SX-E400, while a taller and more experienced rider may be ready for the SX-E700 MX.
My Take as a British Motocross Rider
The SX-E500 is probably the model I would look at first for the biggest group of riders in the RFN Warrior Kids range.
It has more of a proper motocross-bike feel than the smaller SX-E400, but it is still manageable enough for a confident young rider who is learning.
The three speed settings are a big advantage because they let parents introduce the performance gradually rather than giving the rider everything immediately.
For a child who already rides confidently on two wheels and wants their first genuine electric dirt bike, the SX-E500 is a very strong all-round option.
