Hey there, fellow e-bike enthusiasts! I'm a supplier of Fat Tire Moped Style Ebikes, and I know how frustrating it can be when your bike's motor goes kaput. But don't worry, replacing the motor on your Fat Tire Moped Style Ebike isn't as daunting as it might seem. In this blog post, I'll walk you through the process step by step, so you can get your bike back on the road in no time.
Step 1: Gather Your Tools and Materials
Before you start tinkering with your bike, you'll need to gather a few tools and materials. Here's what you'll need:
- A set of Allen wrenches
- A socket wrench set
- A torque wrench
- A screwdriver set
- A new motor that's compatible with your bike
- Electrical tape
- Zip ties
- Lubricant
Step 2: Prepare Your Bike
The first thing you need to do is prepare your bike for the motor replacement. Start by turning off the bike's power switch and removing the battery. This will prevent any electrical shocks or short circuits while you're working on the motor.
Next, you'll need to remove the wheel that contains the motor. This will vary depending on the type of bike you have, but in most cases, you'll need to loosen the axle nuts or quick-release skewer and remove the wheel from the frame. Once the wheel is removed, you can set it aside on a clean, flat surface.
Step 3: Remove the Old Motor
Now that the wheel is removed, you can start removing the old motor. The motor is typically attached to the wheel hub with a series of bolts or screws. Use your socket wrench or Allen wrenches to loosen and remove these bolts, being careful not to drop them.
Once the bolts are removed, you should be able to gently pull the motor out of the wheel hub. If the motor is stuck, you can use a little lubricant to help loosen it. Be sure to keep track of any washers or spacers that come off with the motor, as you'll need to reinstall them later.
Step 4: Install the New Motor
With the old motor removed, it's time to install the new one. Start by lining up the new motor with the wheel hub and inserting it into place. Make sure the motor is properly seated and that the bolt holes align with the holes in the wheel hub.
Once the motor is in place, you can start reinstalling the bolts or screws. Tighten them using your socket wrench or Allen wrenches, but be careful not to overtighten them. Over-tightening the bolts can damage the motor or the wheel hub.
Step 5: Reconnect the Electrical Connections
Now that the new motor is installed, you'll need to reconnect the electrical connections. The motor is typically connected to the bike's controller and battery with a series of wires. These wires are usually color-coded, so it's important to pay attention to which wire goes where.
Start by connecting the motor wires to the controller. This may involve plugging in a connector or soldering the wires together, depending on the type of bike you have. Be sure to use electrical tape to secure the connections and prevent any loose wires from shorting out.
Next, you'll need to connect the battery wires to the controller. Again, this may involve plugging in a connector or soldering the wires together. Make sure the connections are secure and that there are no loose wires.
Step 6: Reinstall the Wheel
With the new motor installed and the electrical connections reconnected, you can now reinstall the wheel. Start by lining up the wheel with the frame and inserting the axle through the wheel hub and the frame. Make sure the wheel is properly centered and that the axle is tightened securely.


If your bike has a quick-release skewer, make sure it's tightened properly. If you're using axle nuts, use your torque wrench to tighten them to the manufacturer's recommended torque specification. This will ensure that the wheel is properly secured and that it doesn't come loose while you're riding.
Step 7: Test the New Motor
Once the wheel is reinstalled, it's time to test the new motor. Reinstall the battery and turn on the bike's power switch. You should hear the motor start up and feel the bike move forward when you twist the throttle.
If the motor doesn't start or if there are any strange noises or vibrations, there may be a problem with the installation. Double-check all the electrical connections and make sure the motor is properly seated in the wheel hub. If you're still having problems, it may be a good idea to consult a professional bike mechanic.
Step 8: Finalize the Installation
Once you've tested the new motor and everything seems to be working properly, you can finalize the installation. Use zip ties to secure any loose wires and prevent them from getting caught in the wheel or other moving parts. You can also use electrical tape to cover any exposed wires and protect them from the elements.
Finally, reinstall the wheel cover or fender if you removed it earlier. This will help protect the motor and the electrical connections from dirt, debris, and water.
