More airflow. More capacity. Less waiting.
The CYCPLUS AS2 Pro Max is the high-capacity model of the AS2 range. Its powerful brushless motor produces airflow of up to 30 litres per minute, making it especially suitable for large MTB and gravel tyres.
The digital pressure display shows the tyre pressure in real time. Select your target pressure and the pump switches off automatically when the selected pressure is reached.
With a maximum pressure of 120 PSI, the AS2 Pro Max handles everything from high-pressure road tyres to high-volume mountain bike tyres.
Designed for high-volume tyres
The AS2 Pro Max is the right choice when airflow and battery capacity matter more than achieving the lowest possible weight.
It is particularly suitable for:
The larger 600 mAh, 11.1 V battery provides more inflation capacity than the smaller AS2 models.
Fast and accurate inflation
According to the manufacturer's test figures, the AS2 Pro Max can inflate a 700 x 25C road tyre from 0 to 80 PSI in approximately 40 to 50 seconds. A fully charged battery can provide up to eight inflations at this pressure.
For a 29 x 2.2 inch MTB tyre, the pump reaches 50 PSI from empty in approximately 130 to 140 seconds. It can also provide up to seven pressure top-ups from 30 to 50 PSI.
Automatic stop and real-time display
Select the desired pressure in PSI or bar and start the pump. The display allows you to monitor the pressure throughout inflation. Once the target pressure is reached, the pump stops automatically.
This makes pressure adjustments faster, more repeatable and easier before every ride.
Presta and Schrader compatible
The AS2 Pro Max works with both Presta and Schrader valves. The included extension hose provides easier valve access and reduces heat transfer to the valve.
Always use the extension hose with plastic or resin TPU tube valves.

Which CYCPLUS pump should you choose?
Choose the AS2 Pro Max when you need the strongest airflow and largest battery capacity for MTB, gravel or bikepacking.
Choose the AS2 Pro when you want a lighter all-round pump for road, gravel and everyday cycling.
Choose the AS2 Ultra when the lowest possible weight is your main priority.
Please note that the pump becomes hot during operation. Use the included heat protection sleeve and allow the pump to cool between repeated inflations.
