    Question
    Noise and vibration are only present when riding on a bicycle, so there is no way to take a video while driving. If you turn the pedal while stopped, there is no problem. I will return quietly. I can show you a video showing the rear wheel in idle state, but I do not know if it will help you to diagnose the problem.
    Question
    In addition, I think that abnormal noise and vibration occur only when the load is applied to the motor.
    It looks like normal because it does not take a load when you turn the wheel.
    Answer
    Do you have a sound when you are dragging a low-voltage battery?
    Question
    This is a video from a stopped state. No more noise.
    Question
    It was somewhat dangerous, but I took a video while driving. A little more torque on the hill, the more noise it gets.
    Answer
    Yes, please, please wait a moment.

    Hello, customer
    Did the product issue suddenly occur while you were driving on a flat road?
    (Jun 10, 2018 17:43)
    Question
    It is not severe on flat roads. I am upset in up-slope.
    Answer
    Hello, customer
    We checked with our technician, but the problem with the product is that wheel spokes can be shaken.
    Please check with your customer.
    Thank you ~
    Question
    I've shaken the wheel, but it does not seem like a spokes issue. I will visit the bicycle shop and check it precisely.
    Question
    I checked it at the bike shop, but there is no abnormality in the other parts and it is the conclusion that it sounds in the motor assembly.
    Answer
    Hello, customer
    You will return the rear wheel of the product and contact us at the factory to check it free of charge.
    Thank you ~
    Question
    International shipping is cumbersome. Is there any way to get domestic action?
    Answer
    Hello, customer
    If you want to take action in Korea, you should visit the repair shop by yourself.
    Question
    Yes, I would be grateful if you could provide us with a service center in Korea.
    Answer
    Hello, customer
    We contacted the repair shop today and have not received any reply yet.
    If you want to use it in a hurry, you can have it repaired at another bicycle repair shop.
    I apologize for the inconvenience and thank you very much ~ ~
