How to Make Power Wheels Faster

Seeing your kids happy and enjoying themselves is a pleasing thing for every parent. This is why most parents nowadays prefer gifting their kids with the best power wheels for off-road, rough terrain, or grass.

Remember, kids are an extension of us, and to keep them happy while ensuring they grow up healthier and safer, we often opt for modern recreational activities. So, as much as Power Wheels cars are considered fun toys for kids, they are technically training wheels that help these toddlers grow into outstanding drivers.

While your kid would enjoy the first few miles driving with standard speed, they inevitably end up outgrowing the slow pace and demand for a higher momentum and more acceleration. Like a standard vehicle, these Power Wheels may require some modifications to ace the upgrade, thus giving it a higher tempo.

There are currently two standard methods or ways to make your Power Wheels faster, and they include:

  • Adding a new motor
  • Installing an aftermarket battery

Installing a new motor

Just because these cars are referred to as children’s toys don’t mean you shouldn’t take precautions when making any modifications, especially when trying to speed it up. The following are the steps you would need to take when installing a new motor onto Power Wheels cars. 

  1. Open the motor of your vehicle: Gently flip the car over and take out the wheels to access the targeted black motor hardware. Loosen the screws efficiently using the right-sized screwdriver and gently remove the motor without any struggle. 
  2. Confirm motor compatibility: Make sure that the new motor you intend to install is compatible with your Power Wheels. Check whether it’s the right size and specs. Please take out the brushless motor from your spare car, which is cylinder-shaped and would require you to remove extra hardware for its exposure.
  3. Join a solder-free spade to the pin of the brushless motor: You can opt to buy an affordable spade from a local hardware store near you if you have your doubts about fixing an already-connected spade to the motor or salvage the intended spade off the car’s engine by gently heating it and using a flathead screwdriver to apply some pressure.
  4. Return the brushless motor into the car: Push the motor in spade-end gently, then use a screwdriver to put the screws back into the vehicle’s hardware to hold the battery firmly. 
  5. Connect the wires to the motor: Gently unwrap the original motor’s wires and re-attach them to the installed brushless motor using the same connecting points. At this point, one can even insert a new battery if they wish to do so but must take precaution by disconnecting the cell to avoid getting shocked.
  6. Thread the wheels back on and test-drive your car: At this point, your car is expected to be compatible with the remote made from the brushless motor. However, as a further precaution, you are advised to keep the vehicle upside down as you test it because the speed is significantly increased. 

Installing an aftermarket battery

This is a required method whereby the self-proclaimed “mechanic” should be keen and attentive to detail to avoid mistakes. Like an original car battery, the ones designed for Power Wheels can also be hazardous when inappropriately use or handled.

  1. Pick the desired aftermarket battery. When choosing the right battery for your Power Wheels vehicle, you need to ensure that you pick one that is compatible with the specifications provided in your car’s guide. Every detail, such as the size, chemistry, and voltage, must be exact to avoid overloading cases. Aftermarket batteries are generally much more affordable as compared to brand batteries explicitly designed for Power Wheels cars. 
  2. Take off the top of the original battery. Using a flathead screwdriver, you should ply off the top of the first battery and after the top cracks open, use the same screwdriver to pull its edges away from the top-side components of the battery. Remove the top piece entirely but gently to avoid damaging the battery casing. Be sure to avoid the black connector inside the cell as this will be used to up the new battery to the car and require replacement if damaged. 
  3. Pull the connector away from the battery. Pull the attached positive and negative wires out and gently clip them close to the battery using wire cutters or crimpers. After disconnecting the connector, it would be helpful to recycle the cell at a designated recycling depot in the area. 
  4. Join the fuse to the positive battery connector. Put in a 30 Amp fuse into a fuse holder and strip approximately 1 cm of the wire insulator from each side of the connector and insert the exposed wire into the targeted wire connector and crimp it down to hold it firmly.
  5. Insulate exposed wires. Use female spades to insulate the negative wire of the connector and the remaining part of the fuse wire. 
  6. Insert the connector into the new battery. Be sure to accurately connect the terminals of the cells to their corresponding wires of the connector. The black negative battery terminal is connected to the negative wire of the connector, which also happens to be black. The positive terminal of the cell, red in color, should be connected to the designated connector’s end. 
  7. Test the new battery. When testing whether the process worked, keep your Power Wheels car turned upside down as a precaution because the speed would have significantly increased. 


Installing a battery with a more significant voltage in a lower voltage car might not necessarily burn up the motor, but would rather overwork it and end up killing it in a few months. It would be helpful if you changed the motor to one that accommodates higher voltage. 

If you intend on using more than one battery to cover the exiting voltage requirement required by the motor, you should connect them in parallel. If you happen to join them in series, they might not charge when drained. 


If you need more speed on your Power Wheels, be sure to try out the above methods and get your motor pumping in more momentum for a faster dash. Remember, ensure that your child’s seat belt is on when they’re taking the car out for a tour at a higher speed because despite it being a toy, it still runs on the road like any other regular vehicle.
