* Metal vibration may occur due to motor vibration, vibration of the brake disc and pad
during the load section that accelerates during driving. (About 15 ~ 30Km, different for
each product)
This is a phenomenon in which all revolutions (fans, automobiles, ships, etc.) are
vibrating at a specific rotational frequency (rpm) rather than the product. However, if the
continuous noise or metal noise is large, there is a possibility that the disk is bent and
deformed.
* Please note that after running, there is a risk of burns due to the heat on the motor and
brake (especially disk rotor) side.
* Be careful that the bolts of the motor,rim and motor shaft due to the ABS function maby
be loosened.
Important notice
