About this item

【Rapid 120 PSI Inflation for Road & MTB】Why struggle with manual pumping? The A3S electric bike tire pump delivers a powerful 120 PSI maximum pressure, capable of inflating a standard road bike tire to 100 PSI in just 90 seconds. This high-efficiency performance makes it the ideal fast bike inflator for road cycling, mountain biking (MTB), and daily commuting, significantly reducing physical effort during rides.
【Intelligent Smart Auto-Stop Technology】Eliminate the guesswork of tire pressure. Equipped with a high-precision digital sensor, this smart bike pump features an automatic shut-off function that stops precisely when your preset pressure is reached. With three intuitive preset modes, it prevents over-inflation, ensuring your tires are always at the optimal PSI for safety and speed.
【Advanced LED Display & Dual Valve Compatibility】Designed for seamless usability, the integrated LED display screen provides real-time pressure readings even in low-light conditions. The A3S is a true all-in-one bike pump compatible with both Presta and Schrader valves. We’ve included an extended air hose to make connecting to tight valve stems easier and more efficient than traditional screw-on pumps.
【Ultra-Lightweight 137g Pocket-Sized Design】Engineered for the minimalist cyclist, this tiny electric air pump weighs only 137g (4.8oz). Its compact, sleek frame fits perfectly into a cycling jersey pocket, saddle bag, or water bottle cage. It is the ultimate portable bicycle inflator for long-distance bikepacking and emergency roadside repairs, replacing bulky CO2 cartridges.
