Don't know much about these things, but if the bushes wore out what is left might have slid inbwteen the moving parts inside. This sometimes happens to old bush alternators and tools. Just a possible guess...

Have you looked inside yet? That will probably tell you what you need to know.

yea i dont know anything about electric bike motors myself and am just looking for help to give me ideas where to start so i appreciate you for replying. i have not taken it apart and dont think i will until i can find some diagrams or someone that can guide me or whatever. the plug for the motor gets real hot whenyou run it and the hub makes like a low grinding or growl noise when you give it power but stops when no power is applied. im probably just waisting our time with this but if they can be worked on maybe ill save myself some money. anyways thanks again

How old is that motor? Five years, maybe? Well the bearings could be dry, so they get hot and seize.

Anything you have to identify the motor? Direct drive or geared (i.e. does it freewheel easily)?

well it free wheels easier now that i kinda gave it a good push forward due to getting frustrated. i just bought 3 new batteries 12v 12amh charged till the green light came on and it runs like the batteries are real low. the hub has usaaotema and chinese characters on it.

Aotema. Here's the US dealer.

If it's real old, I'd still pull the cover and see if there's anything inside that can be oiled. If it spins backward about as easily as it spins forward, it probably is direct drive. If higher resistance backwards, then it's likely geared. Gears can use some grease. Wouldn't hurt to oil the bearings on either type.

And I would keep those front nuts real tight and add torque arms as soon as I could.

+1 with DW; looks like a direct drive motor so should last a long time; lubricate bushings as suggested. Batteries may be suspect if you purchased from ebay.

The Bafang hub motors often dislodge their magnets. Perhaps yours has the same problem. Taking it apart wouls be a good thing to do and inspect what could be wrong internally.
