Introduction
One of the most common questions parents ask when buying a kids' electric ride on car is: what does the voltage actually mean, and which one should I choose? The voltage of a ride on car's battery is the single most important specification — it determines the speed, power, suitability by age, and overall riding experience.
This guide explains exactly what 6V, 12V, and 24V mean in practical terms, who each voltage is best suited for, and how to choose the right one for your child.
What Does Voltage Mean on a Kids' Ride On Car?
Voltage (V) refers to the electrical potential of the battery. In simple terms, a higher voltage means more power delivered to the motor, which translates to higher top speed, better performance on inclines and grass, and a higher weight capacity.
It does not mean the car is automatically unsafe — all kids' ride on cars are designed with age-appropriate speed limits. But it does mean that a 24V car is significantly more powerful than a 6V car, and choosing the wrong voltage for your child's age can result in a car that's either too slow and frustrating, or too fast and difficult to control.
6V Kids' Ride On Cars
Who is 6V for?
6V ride on cars are designed for toddlers and young children aged 1 to 4 years old. They are the entry-level option and prioritise safety and simplicity above all else.
Key characteristics of 6V ride on cars:
- Top speed: 2–3 mph — a gentle walking pace
- Battery life: approximately 30–45 minutes per charge
- Weight capacity: typically up to 25–30 kg
- Speed settings: usually single speed
- Terrain: best suited to smooth, flat surfaces such as patios and driveways
- Parental remote: commonly included, essential for this age group
Pros of 6V:
- Safe, gentle speed ideal for young children still developing coordination
- Lightweight and easy to move around
- Lower price point
- Simple controls — easy for toddlers to operate independently
Cons of 6V:
- Children outgrow them relatively quickly (typically by age 4–5)
- Struggles on grass or inclines
- Shorter battery life than higher voltage models

12V Kids' Ride On Cars
Who is 12V for?
12V ride on cars are the most popular choice overall, suited to children aged 3 to 8 years old. They offer a significant step up in power and features compared to 6V models, while remaining safe and manageable for younger riders.
Key characteristics of 12V ride on cars:
- Top speed: 3–5 mph
- Battery life: approximately 45–60 minutes per charge
- Weight capacity: typically up to 35–40 kg
- Speed settings: usually 2 speeds (low and high) plus reverse
- Terrain: handles grass and gentle inclines well
- Parental remote: often included, particularly on models for younger children in this range
Pros of 12V:
- Best balance of power, safety, and value
- Wide range of models and styles available
- Suitable for a broader age range — good longevity
- Handles garden terrain including grass much better than 6V
- More realistic features: working lights, sounds, music, opening doors
Cons of 12V:
- May feel underpowered for older, heavier children (8+)
- Heavier than 6V models

24V Kids' Ride On Cars
Who is 24V for?
24V ride on cars are performance models designed for older children aged 6 to 12 years old, particularly those who are confident riders and want a more powerful, realistic experience. They are also the right choice for heavier children who have outgrown the weight capacity of 12V models.
Key characteristics of 24V ride on cars:
- Top speed: 5–8 mph
- Battery life: approximately 60–90 minutes per charge
- Weight capacity: typically up to 50–60 kg
- Speed settings: 2–3 speeds plus reverse
- Terrain: handles grass, gravel, and gentle off-road terrain well; some 4WD models handle more challenging terrain
- Parental remote: sometimes included; less essential at this age
Pros of 24V:
- Significantly more power — handles hills and rough terrain with ease
- Higher weight capacity — suitable for older, larger children
- Longer battery life
- More premium features: leather seats, rubber tyres, MP4 screens, 4WD
- More realistic driving experience
Cons of 24V:
- Higher price point
- Too fast and powerful for young children
- Heavier and larger — requires more storage space
- Longer charge time (typically 10–12 hours)
Quick Comparison: 6V vs 12V vs 24V
| Feature | 6V | 12V | 24V |
|---|---|---|---|
| Recommended age | 1–4 years | 3–8 years | 6–12 years |
| Top speed | 2–3 mph | 3–5 mph | 5–8 mph |
| Battery life | 30–45 min | 45–60 min | 60–90 min |
| Weight capacity | Up to 30 kg | Up to 40 kg | Up to 60 kg |
| Grass performance | Poor | Good | Excellent |
| Typical price range | £80–£150 | £150–£300 | £250–£600+ |
Which Voltage Should I Choose?
The answer depends on three things: your child's age, their weight, and where they'll be riding.
- Choose 6V if your child is under 4, is a first-time rider, or will be using the car primarily on smooth, flat surfaces indoors or on a patio
- Choose 12V if your child is between 3 and 8, will be riding on grass or in the garden, and you want a good balance of power, features, and value — this is the most popular choice for good reason
- Choose 24V if your child is 6 or older, is a confident and experienced rider, will be using the car on varied terrain, or has outgrown the weight limit of a 12V model
A note on buying ahead:
It's tempting to buy a higher voltage model thinking your child will "grow into it" — but this isn't recommended. A 24V car travelling at 8 mph is genuinely fast and can be difficult for a young child to control safely. Always match the voltage to your child's current age and ability, not where you hope they'll be in two years.
Frequently Asked Questions
Is a higher voltage ride on car more dangerous?
Not inherently — but a higher voltage car is faster and more powerful, which makes it less suitable for young children. A 24V car used by a confident 8-year-old in a garden is perfectly safe. The same car used by a 3-year-old is not. Always match the voltage to the recommended age range.
Can I use a 12V charger on a 6V battery?
No. Always use the charger supplied with the car or a verified replacement with the correct voltage. Using the wrong charger can damage the battery or create a safety hazard.
My child is between age ranges — which voltage should I choose?
If your child is between age ranges, consider their weight and confidence level. A small, less confident 5-year-old may be better suited to a 6V model; a large, confident 5-year-old may be ready for 12V. When in doubt, choose the lower voltage — you can always upgrade later.
Do 24V ride on cars take longer to charge?
Yes. 24V models typically require 10–12 hours for a full charge, compared to 8–10 hours for 12V and 6–8 hours for 6V models. Always charge overnight and avoid leaving on charge for more than 24 hours continuously.
What voltage is best for grass?
12V handles most garden grass well. 24V is the better choice for longer grass, slopes, or mixed terrain. 6V models are not recommended for grass use as the motor can struggle and battery life is significantly reduced.
Summary
Choosing the right voltage is the most important decision when buying a kids' electric ride on car. In short: 6V for toddlers, 12V for most children, 24V for older and more experienced riders. Match the voltage to your child's current age, weight, and the terrain they'll be riding on, and you won't go wrong.
