2 Easy Methods to Modify Power Wheels to Go Faster

Modify Power Wheels to Go Faster - Tips


One of the easiest ways to make a power wheel faster is upgrading the parts of the vehicle. Usually, the gearbox, electronic speed controller, and battery are in charge of the speed. They have a speed cap and can only go as fast as these pieces allow. If, during the upgrade process, you accidentally break some plastic parts of the power vehicle, using the right glue can serve as a viable solution.

Method 1: Switch Battery

The power wheels upgrade we will do here is changing the 12V stock battery for an 18V tool battery.

You will need:

  • Wire strippers
  • Crimping tool
  • Screwdriver
  • Crimp spade wire connectors
  • 18V tool battery

Step 1: Cut the battery wires

Cut the wires in the middle without letting them touch. Strip about ¼ of the connector wires.

Step 2: Attach the connectors

After making sure the positive and negative wires, attach the connectors using a crimping tool.

Step 3: Connect to the 18V battery

Connect the wires to the higher voltage 18V battery. Ensure each wire goes into the proper positive and negative slots.

Step 4: Wedge the new battery

Find a place to securely wedge the new battery in the power wheel.

Step 5: Test the power wheels out

You need to pick up the ride-on toy and test it out. This step will make sure that the battery connection works.

Some power wheels have an extra spot for an additional battery. For this case, you can wire in two 12V batteries to make it faster at 24V. Two batteries will double the motor’s spinning capacity, which propels the vehicle to run at a faster speed.

Method 2: Install a New Motor

Another way to soup up a power wheel is by installing a new motor. Learn how with the following section.

You will need:

  • Compatible motor
  • Flathead screwdriver
  • Crosshead screwdriver
  • Set of pliers
  • Wheel wrench

Step 1: Remove the car seat

Detach the car seat and remove the red positive terminal from the battery.

Step 2: Remove the wheel

Carefully take off the wheel trims. Be patient in removing the clip since they are brittle. Then, remove the wheel from the car.

Step 3: Check and remove the connection.

Identify where it connects to the motherboard, push the tab and remove it. Next, slide the motor off the axle.

Step 4: Reassemble and reconnect

With the new motor, reassemble by sliding it onto the axle. Push the connections into the compartment and attach the plug to the motherboard.

Step 5: Attach the battery terminal and test

Reattach the wheel in the correct order while making sure that it lines up with the gearbox. Return the seat and test the vehicle.

This technique is effective in turning a ride-on toy into one that can take on any off-road adventure. However, you should know that it can be pretty expensive.
