Intelligent electric bicycles are usually placed outdoors. External changes plus working heat generated internally by various electronic parts may result in pressure being accumulated, which may cause damage to electronic equipment and ruptures of casing rubber rings in the longer run. Therefore, the cavity is usually not completely sealed, leaving channels connected to the external environment to equalize pressure. But this may cause dust and rain intrusion, leading to electronic components damage and short circuits, posing great safety concerns. IPRO screw-in vents offer effective waterproof and dust-proof protection, and can quickly equalize pressure, prevent sealing structure failure and casing deformation, and ensure safe and intelligent travel.
