Hub Motor Making New Noise

[boba7523]

Hi All,

I have the Aniioki A8 Dual Motor with about 400 miles on it. This motor has metal planetary gears instead of nylon. I know noises from the hub motor is normal, but today, the front motor started making 2 new noises.

• The first noise sounds like a slight chirp that only happens at around 28-30 mph and then disappears (~9, 14, 31 second mark)
• The second noise sounds like a "ohm" sound whenever I let off the throttle and only happens at mid to higher speed also (~11, 16, 36, 40 second) mark. Otherwise, the motor sounds normal.

I've uploaded a YouTube video of the sound. When I touched the motor through the plastic case, it was barely warm. Below is the specification.

Maybe this is normal, but I just wanted to inquire others here just in case so I can catch problems early. Appreciate your help!

Sounds like a motor with metal gears ( loud ) working in decent condition to me.
