The Dunlop valve on a bicycle does not let air in because it is a one-way valve designed to only allow air to be released from the tire when the valve core is depressed. When the valve core is not depressed, the rubber sleeve inside the valve remains sealed, preventing air from entering the tire. This design helps to maintain the pressure inside the tire and prevent air from escaping unintentionally. **
