All of our e-bikes are splash-resistant but using too much or pressurized water can damage them.   1. To wash the frame or tires of an e-bike, use a damp cloth with a small amount of soap if necessary. It's best to clean your bike soon after it becomes dirty to avoid difficult-to-remove residues.   2.To clean your disc brakes of e-bike, use only water, because soap residue can cause them to squeal.   3. The LCD display and battery assembly cannot be washed directly with water. Please wring out the water with a damp towel, and then wipe gently. After cleaning, make sure they don't have any water left on their surfaces and inside.   4. When cleaning connectors, use only compressed air and 90% alcohol if needed.   5. Contact your local bike mechanic for recommendations on drivetrain lubricationbased on your local weather conditions.
