TINY BIKE PUMP is a compact emergency pump designed for cyclists to inflate various bicycle types. It is not suitable for inflating swimming equipment or balloons due to its low air flow volume. Does TINY BIKE PUMP generate excessive heat during inflation? No, while the air pump's temperature may rise, TINY BIKE PUMP is equipped with a temperature protection feature that automatically powers off at a certain high temperature. Please be sure to install the silicone cover when using it. Is TINY BIKE PUMP compatible with all bike types? Indeed, TINY BIKE PUMP works with both Schrader and Presta valves, catering to the common bikes available in the market. Note: When using the Schrader valve, ensure a tight fit to prevent valve-related air leaks. Can TINY BIKE PUMP display tire pressure? No, for the sake of minimizing size and weight, TINY BIKE PUMP lacks a display screen to show tire pressure. Cyclists can gauge tire pressure by assessing the degree of tire firmness. Does TINY BIKE PUMP release air automatically if tire pressure is too high? No, simply partially connect the valve, allowing for manual air release to reduce tire pressure as needed.
