How to Change a Brushless Motor on a Kids’ Electric Quad Bike: A Step-by-Step Guide

This guide is for the Neo Outlaw 48v Kids Electric Quad Bike but the general principal to replace motors on most electric kids quad bikes will be the same.

Replacing the brushless motor on your child’s electric quad bike might seem like a daunting task, but with the right steps, you can get the job done efficiently. Follow this simple guide to ensure a smooth process, and remember to take pictures before disconnecting any components to help you during reassembly.

Tools You’ll Need:

• Wrenches and screwdrivers
• Pliers
• A clean, flat workspace
• Safety gloves (optional)

Step-by-Step Instructions

1. Remove the Rear Wheels

Start by detaching the rear wheels from the quad bike. This step gives you better access to the motor and the surrounding components.

2. Remove the Brake Calliper

Unscrew and remove the brake calliper from the brake disc. Keep the screws in a safe place and take note of how the calliper is positioned.

3. Disconnect the Motor Cable from the Control Module

Locate the cable that connects the motor to the control module and unplug it. This cable is often a clip-on connector, so it should come off with a gentle pull.

4. Disconnect the Green, Yellow, and Blue Wires

The motor’s power wires—green, yellow, and blue—are screwed into the control module. Use a screwdriver to unscrew and disconnect these wires. Take a photo before disconnecting so you know their correct placement later.

5. Detach the Axle from the Frame and Motor

The axle that holds the rear wheels is also connected to the frame and motor. Unscrew it carefully from both sides. Be sure to support the motor and axle to prevent them from falling.

6. Remove the Old Motor

Once the axle is detached, slide the old motor out of its position. Check the area for any debris or damage before proceeding with the new motor.

7. Install the New Motor

Position the new motor in the same spot where the old one was removed. Ensure it aligns properly with the axle and frame.

8. Reconnect the Wheel Axle

Reattach the wheel Axle to the frame and motor on both sides. Tighten the screws securely but avoid overtightening.

9. Reconnect the Green, Yellow, and Blue Wires

Refer to the photos you took earlier and reconnect the green, yellow, and blue wires to the control module. Ensure they are tightly secured to avoid electrical issues.

10. Reconnect the Motor Cable to the Control Module

Plug the motor cable back into the control module. Make sure it clicks into place firmly.

11. Reattach the Brake Disc and Calliper

Position the brake disc on the wheel axle, then reattach the brake calliper. Ensure everything is aligned properly and securely fastened.

12. Reinstall the Rear Wheels

Finally, attach the rear wheels back onto the axle. Tighten the nuts or bolts securely, ensuring the wheels spin freely and without wobbling.
