Lvbu wheel's motor has equipped SKF waterproof bearings, the controller is sprayed with waterproof glue and filled with glue, and the battery is packaged with a heat shrinkable tube and then coated with waterproof glue. Therefore, the waterproof grade is P65. You don’t need to worry about water ingress when riding in the rain. But we recommend that don’t put the bike in the rain for a long time statically when you don’t ride it. Please park it indoor when it’s raining. Because the water would penetrate into the motor in the form of vapor. When the vapor accumulates to a certain amount, it would damage the PCB or the battery.
