*When first assembling the "special tire" and "special wheel," the two are not sealed and have many gaps, so air may not fill in properly. (This is not a problem if the tires are already sealed, such as when adding air.) As this is a characteristic of tubeless tires, we recommend that you inquire in advance with your wheel manufacturer or a specialized bicycle shop about the correct method for inflating tires for initial assembly. Comfort: This portable electric air pump is perfect for inflating tires (bicycles), city bikes and footballs (up to 5 bar). Auto-stop function: The air pump provides three different pressure units (PSI, bar, kPa) and will automatically shut off when it reaches the set value [Digital Display & LED Light] Clear display shows current value, set value, and remaining amount. LED illuminates the area around the bulb. AUTOMATIC SWITCH-OFF: The cordless air pump automatically switches off to conserve energy when not in use and can be easily charged via USB-C.
