The Cycplus AS2 Pro cycle tire inflator is a compact and efficient tool designed for cyclists looking for a portable solution to tire inflation. Here’s a detailed review based on various sources:

Design and Portability


The Cycplus AS2 Pro is praised for its compact size and lightweight design, making it easy to carry in a pocket or saddlebag. It weighs around 117 grams and maintains a sleek aluminum body, which is both durable and aesthetically pleasing. The inclusion of a silicone cover and a waterproof bag further enhances its portability and protection against the elements​.



The AS2 Pro features a 420 mAh battery, capable of inflating two 700×32 tires up to 1000 psi on a single charge. The Pro Max version, with a 600 mAh battery, can inflate up to four tires. Both models support pressures up to 120 psi, suitable for various tire types including road bikes, mountain bikes, and even some sports equipment​.



One of the standout features is the high-contrast LCD screen that displays real-time air pressure, and battery status, and allows for easy pressure adjustments. The user interface is simple, with three buttons for power and pressure adjustments, making it straightforward to use even for those not familiar with electronic inflators. The automatic shut-off feature ensures the pump stops once the desired pressure is reached, preventing over-inflation​.

Cycplus AS2 PROAccessories and Compatibility


The pump comes with adapters for both Presta and Schrader valves, a ball needle adapter, and an extension hose. The extension hose is particularly useful for positioning the pump and provides thermal insulation to protect against heat during use. This versatility allows the pump to be used across different bikes and inflatables​.

Battery Life and Charging


The Cycplus AS2 Pro charges via a USB-C port and can be fully charged in about an hour. The Pro Max’s larger battery means longer usage between charges. Both models can withstand over 200 charge cycles with minimal battery degradation, indicating good long-term reliability​ (CYCPLUS)​.



Some users have noted that the pump is quite loud during operation. Additionally, the cost is relatively high compared to traditional floor pumps, but the convenience and portability might justify the price ($109) for many cyclists.



The Cycplus AS2 Pro and Pro Max are highly recommended for cyclists needing a reliable, portable, and efficient tire inflator. Their compact design, easy-to-read display, and versatile use across different types of tires make them a valuable addition to any cyclist’s toolkit. While the noise and price might be slight drawbacks, the overall performance and convenience make them worthwhile investments.
