How to Change the Internal Controller on a Golden Motor Hub Kit

Today, I’ll show you how to replace the internal controller on your Golden Motor hub motor kit.

The first step is to remove the six bolts securing the controller cover. Use a 3 mm hex key to take these bolts out. Once the bolts are removed, you’ll also need to remove the nuts and washers underneath—otherwise, the cover won’t come off.

After removing these fasteners, carefully take off the cover. Be sure to unroll and free the wires first so the cover can come off smoothly without damaging anything.

With the cover removed, you now have access to the internal controller. Before proceeding, I’ll mention that all parts I refer to in this video will be listed in the description below in case you need replacements.

Next, unscrew the six screws that hold the controller in place. Before pulling the controller out, remove the wire clip securing the wiring to the axle. This clip is often difficult to remove without damage, but replacements are inexpensive. Alternatively, you can secure the wiring with a zip tie when reinstalling the new controller, as long as the wiring remains fixed to the axle to prevent tangling when the motor spins.

Removing the old controller can be tricky by hand. I usually use a flathead screwdriver and a mallet or small hammer to gently pry it loose. Insert the screwdriver under one of the larger fins—avoid the smaller fins as they may break—and slowly work it free.

Once out, you can see the three phase wires and the hall sensor connector. If any clips are damaged during removal, replacement parts are available and linked below.

To disconnect the old controller, unplug the three phase wires and the hall sensor cable.

Now, it’s time to install the new controller. Start by plugging in the hall sensor’s six-pin connector—you should hear a satisfying click when it’s fully engaged. Next, connect the three phase wires: the yellow wire goes next to the hall sensor plug, the blue wire plugs in beside the yellow, and the green wire connects next to the capacitor.

Be gentle when plugging in the phase wires; they use push connectors that require a firm but careful push to avoid damaging wires or tangling. Once connected, ensure all wires are neatly arranged without kinks or squeezes.

When reinstalling the controller, carefully align it and avoid crushing any wires. Secure it in place with the six screws you removed earlier.

Finally, put the cover back on, secure it with the nuts and washers, then tighten the six bolts to finish the job.

And that’s it—changing your internal controller is straightforward and easy to do!
