What should you note regarding the trailer coupling, when transporting pedelecs on a rear-mounted carrier system?

Your answer is correct because all three points are important for safely transporting pedelecs on a rear-mounted carrier. First, the carrier system must be specifically designed for carrying bikes or pedelecs, ensuring it securely holds the load without damaging the vehicle. Second, the trailer coupling must be able to handle the vertical load from the carrier and the bikes; otherwise, it may not be stable or safe during driving. Third, adjusting the car's tire inflation pressure is necessary to compensate for the added weight, maintaining proper tire performance and vehicle handling. Ignoring any of these factors can compromise safety and vehicle control.
