CYCPLUS AS2 PRO MAX ELECTRIC PUMP
The Cycplus AS2 Pro Max is the most powerful and high-capacity model in the AS2 series. While the standard AS2 and AS2 Pro models are designed for emergency road-side repairs, the Pro Max is built as a portable compressor capable of handling high-volume needs, including mountain bike, motorcycle, and even car tires.
It features a robust 11.1V 600mAh battery, providing nearly double the capacity of the standard Pro model. This allows for up to 7 full inflations of a road tire (700x25c) to 120 PSI on a single charge. It also features a larger LED display for real-time pressure monitoring and a high-precision auto-stop function that cuts off once your target PSI is reached.
Key Features
High-Volume Performance: Equipped with a brushless motor that delivers 30 liters of air per minute, making it fast enough to inflate a 29x2.2 MTB tire in roughly 60 seconds.
Intelligent Auto-Stop: Set your desired pressure on the backlit LED screen; the pump will automatically stop once it hits the target with ±1 PSI accuracy.
Dual Valve Compatibility: Works natively with Schrader valves and includes a screw-on Presta adapter and a flexible extension hose to protect delicate valve stems.
Endurance Power: The upgraded battery can handle approximately four 700x25c tires from 0 to 120 PSI or multiple top-offs for larger volume tires.
Fast USB-C Charging: Recharges from empty to full in about one hour via a standard USB-C port.
Heat Protection: Includes a tailored silicone sleeve to protect your hands, as the aluminum body can become hot during high-pressure or high-volume inflation.

✅ Why This IS For You
High-Volume Riders: If you ride MTB, Gravel, or E-Bikes and need to move a lot of air quickly without the physical effort of a mini-pump.
Group Ride Hero: With enough battery for 7+ top-offs, it’s the perfect tool to carry if you are the designated mechanic for a group.
International Travelers: Unlike CO2 canisters, the AS2 Pro Max is airline-safe, making it an essential companion for bike tours and overseas races.
❌ Why This May NOT be for you
Weight Weenies: At 205g, it is significantly heavier and bulkier than the ultra-light AS2 Ultra (87g) or the mid-range AS2 Pro (120g).
Stealth Use: The pump is loud (roughly 83dB), similar to a vacuum cleaner. It is not ideal for quiet, early-morning adjustments in shared housing or campsites.
Long-Term Reliability: Like any electronic device, it relies on a battery. For remote, multi-day bikepacking trips, many riders still carry a small manual pump as a backup.
