Your eBike’s motor is one of the most crucial components of the whole vehicle. If your motor stops working properly, then your eBike becomes just a normal bicycle. With how much electric bikes weigh. that will not be an ideal situation to be in.
Follow these steps to learn how to repair or replace your electric bike motor.
Use your standard wrench to remove the bolts holding the wheel’s axle in place on the bike’s frame. Place the nuts and bolts in a secure location; you’ll need them later to replace the wheel in its original spot. It’s also important to note that your wheel will remain attached to the battery pack.
On the side that doesn’t contain the wire, remove the additional set of nuts and bolts using your standard wrench. As before, place the nuts and bolts in a secure location for later use.
Use your Allen wrench to unscrew the bolts securing the motor cover. These screws can be extra tight, so you may need to use extra force to remove them. As with the nuts and bolts from the previous steps, make sure you place these screws in a safe location.
Removing the motor from the wheel requires the use of some force, and you’ll need to protect the axle from damage. The easiest way to do so is by using a wooden 2×4 or another thicker piece of wood. Place the wood on a flat and stable surface. We recommend placing it directly on the ground.
Securely grip the tire on both sides and hold the wheel parallel to the ground above the wood board with the non-wire side facing down. Then slam the wheel’s axle down onto the board. You will need to apply a lot of force during this step since the magnets holding the motor in place are very strong. You may need to bring the wheel down several times before it comes dislodged.
Once the motor assembly is free from the wheel, visually inspect its magnets and ball bearings. The magnets should be glued firmly in place, and you can check them simply by wiggling them with your fingers. The ball bearings should spin with ease. You’ll find a similar repair option with a great GenZe ebike.
If your magnets are loose, then you may be able to glue them back into place. Use some super glue to secure the magnets back into place, but make sure you only place the glue onto the back of the magnets. Glue on the face of the magnets will cause more problems. If your ball bearings are sticking, you can use some lubricant to get them loosened up.
There may be times when you can’t diagnose the motor’s problem. In these instances, it’s best to get the bike serviced by a professional repair technician or replaced entirely. We recommend performing this step with a professional.
Once the repairs have been completed or a new motor assembly installed, it’s time to put everything back together. Get all your nuts, bolts, and screws handy and reverse the previous steps. Place the motor back into the wheel and press it into place, letting the magnets do most of the work. Then secure everything back in place with the nuts, bolts, and screws.
