Is it normal for my Hiboy S2 Pro to make a noise?

Yes, it’s generally normal for electric scooters like the Hiboy S2 Pro to make some noise while in operation. However, excessive noise could indicate problems with the motor or wheels. A faint whirring or humming sound is typical due to the electric motor’s operation. If you hear grinding, clicking, or unusual sounds, it might suggest that the bearings need lubrication or that there’s an issue with the brake system. For instance, if you hear a grinding noise when you engage the brakes, this may indicate that brake pads are worn out. Pro tip: Regularly check and maintain your scooter's components to prevent issues. If the noise persists after maintenance, consider contacting customer support for assistance.
