Power Wheels with 24V batteries have a top speed of about 5 MPH on average, and almost none go faster than 6 MPH. A charge lasts about 1-2 hours depending on the terrain and weight of the child. Keep in mind that a 24V car runs on one 24-volt battery pack or on two 12-volt batteries wired in series; wired in parallel, those two batteries would only make 12 volts.
As a parent, it is okay to wonder how fast a 24-volt power wheel goes before making a buying decision. Power wheels are an excellent brand for ride-on cars for kids.
The ride-on toy cars can keep your kids engaged for hours playing outdoors.
However, it is essential to consider the maximum speed of the power wheel to ensure that it is suitable for your little one.
The voltage of the motor and battery in power wheels determines the maximum speed that the car can achieve. The most popular ride-on cars are 6V and 12V, which are ideal for smaller kids.
Some companies produce 24V, 36V, and 48V power wheels that boast higher speeds. It is imperative that you only consider buying 24V or 36V power wheels for older kids.

How Fast can 12V in MPH
Before exploring how fast a 24V power wheel is, let’s take a look at 12V power wheels. A car with a 12V battery and 12V motor can achieve a maximum speed of 4MPH. Some go faster: a genuine 12V Power Wheels does 5 mph in high, and my guide to how fast 6V and 12V Power Wheels go has low and high speeds by type and model.
The power wheels tend to have two or more speeds to help kids learn how to drive them. Some models come with a parental lock to determine the maximum speed your child can achieve.
A parental lock allows you to lock the gear at a lower speed to reduce collision risk. It comes in handy when your child hasn’t developed the motor skills to go fast.
A 12V power wheel can last for 1-2 hours, depending on the terrain and speed that your little one is riding on. They are ideal for kids who are 4-9 years old. It is the ideal sweet spot between speed and fun for kids.
Is 24V Faster than 12V
So, how fast does a 24-volt power wheel go? A 24V power wheel is faster than a 12V by a little bit. Most 24V power wheels top out at about 4 to 5 MPH and almost none pass 6 MPH, which is still fast for a young child.
Like 12V ride-on cars, 24V power wheels can come with several speed levels that a child can choose. You can opt for a model with a parental lock to control the maximum speed the car reaches.
The power wheels tend to be larger in six, and they can comfortably accommodate bigger kids. Most 24V ride-on cars are rated for ages 3 to 8, so check the age range and weight limit of the model you pick.
You need to consider the driving skills of your little one before buying 24V power wheels. The high speed increases the risk of injuries and collusions for reckless drivers.
The battery life of 24V power wheels is usually about 1-2 hours per charge, about the same as a 12V car. They cope with gravel, grass, tarmac and gentle slopes better than most 12V cars, but steep hills are still off-limits.
The beauty of 24V power wheels is that they can go fast even when carrying heavy kids.
Can you put a 24 Volt Battery in Power Wheels
Yes. You can upgrade 12V battery power wheels into 24V, but it’s a full rebuild, not a battery swap: 24V-rated motors and gearboxes, new wiring and a 24V charger. Put a 24V battery in a stock 12V car and it won’t last long.
A 24V battery is not compatible with a 12V motor. Doubling the voltage roughly doubles the speed and quadruples the power and heat in motors and gearboxes built for 12V, and one of the biggest upgrade-parts makers says even a performance 550 motor may not last a day at 24V.
There is a right way to upgrade power wheels into a 24V battery-powered ride-on toy. An adult who is handy with tools can do the conversion, and our guide to modifying Power Wheels lists everything a 24V conversion needs.
· What Do You Need
First of all, you need to buy a suitable 24V battery for your power wheels. Check out the battery dimensions for the power wheels model you have online. Several manufacturers produce 24V batteries for power wheels.
Second, you need to find a 24V motor for your mode of power wheels. Replacing the 12V motor ensures that the new motor can keep up with the battery power output.
Third, replace the wiring and switches to handle the new voltage, and put a fuse on the + wire at the battery. A 24V conversion kit for your make and model bundles most of these parts, so you don’t have to track down every piece.
An electronic speed controller rated for 24V is worth adding too: it won’t raise the top speed, but its soft start saves the gears. You may also need a step-down converter for any 12V lights.
Finally, you need an instruction manual on how to do the conversion. You can easily find a video detailing the conversion on YouTube, which can assist you if you are not familiar with cars.
Don’t forget 24V-rated gearboxes with steel gears, since the stock plastic ones strip, and a 24V charger, since the car’s 12V charger can’t charge a 24V pack. It’s a bigger job than it looks, and it’s only for older kids.
· Do The Conversion
The hard part of the conversion is switching out the motor. You can search online and find out the location of the motor in your power wheels models.
Some have it at the front, and for others, you will need to flip the car. Most power wheel motors have a cover to protect the kids in case something goes wrong.
Remove the cover and carefully remove the motor. Take note of the wires’ attachments so that you can mimic the connections on the new motor.
Close the motor cover and firmly install the screws. After that, open the area where the battery is and remove the old battery.
Ensure that you install the new battery correctly with the positive wires on the positive terminal and vice versa. Close the battery slot when you are done. Screw back the lid of the battery cover.
· Do A Test Drive
Once everything is back in place, do a test drive to ensure that the car functions as it should. Test it yourself first with the wheels off the ground, then at low speed in an open area, before your child drives it. After a few minutes, feel the wires and motors: if they’re hot, stop and find out why.
Ideally, the car should be faster after the conversion.
· Alternative Method
You can always hire a professional mechanic to convert the power wheels from 12V to 24V. The benefit of hiring a professional is that they have experience and know what they are doing.
You won’t risk having the car malfunction after a while due to poor wiring. Also, you will get professional advice about the best battery and motor for your power wheels.
· Be Safe
Check to see the seat belts are good enough for the increased speed that is offered to the Power Wheels. If you find the seat belts lacking, we suggest upgrading the seat belts as a DIY project to protect your children.
How can I Make my 12 Volt Power Wheels Faster
First check that high speed isn’t locked out. After that, the usual way to make 12V power wheels faster is to take the battery to 18V by adding a 6V battery in series. The combination of a 12V and 6V battery will increase the power output of the power wheels to 18V.
A 12V motor will run on 18V, but it runs hotter and wears out faster, and so do the plastic gears, switches and wiring. Put a fuse on the + wire every time (see where the fuse goes), and plan on stronger gearboxes.
An adult should do the wiring, or have a professional do it. Use a 6V battery for your 12V power wheels with the same Ah rating and type as the 12V one, and charge each battery on its own charger, since the car’s 12V charger can’t charge an 18V pack.
Also, confirm the dimensions of the battery to ensure that it fits well under the hood.
Are the Faster Power Wheels than 24 Volt
Yes. You can find power wheels that are faster than 24-volt cars. Some manufacturers produce 36-volt ride-ons, mostly karts, dirt bikes and quads, that reach about 9 to 17 MPH.
They’re made for older kids and teens: Razor’s 36V models are rated for ages 13 and up, most of them 14 or 16 and up. Your child needs to be a competent driver before you opt to buy 36V power wheels.
There are 48-volt power wheels with a maximum speed of 15MPH, which is a lot of speed in the hands of a child. The 48V power wheels are ideal for teenagers who are 15 years and above.
Keep any ride-on off the road and away from cars, whatever its speed.
Older kids may need a more powerful power wheel to enjoy the ride outdoors. However, invest some quality time in teaching your child how to drive carefully.
Driving at high speeds increases the chances of an accident or injury. Teaching a child the right driving discipline reduces the chances of a collision.
What are the Safety Features in the 24 Volt Power Wheel
When you find out how fast a 24-volt power wheel goes, you may have safety concerns for your child. You must buy protective gear for your child if you are concerned for their safety.
You can invest in a helmet, knee pads, and elbow pads for your child to wear when riding on 24V power wheels.
The power wheels should come with seat belts, fire-resistant materials, lead-free paint, and automatic brakes that stop the car as soon as your child lets off the pedal.
If you want to modify the Power Wheels more you can even add a brake pedal.
You need to check under the hood to ensure the motor and battery have covers. Kids can be tempted to touch the wires under the hood out of curiosity.
Finally, check whether the model of 24V power wheels you want to buy has had any recalls. Websites like CPSC have a list of power wheels that have had recalls and the reasons for the recalls.
You can also see the rating of the power wheels models that you are considering buying for your little one. Learn more about ride on car safety here.
