Compact power for every ride

The CYCPLUS AS2 Pro is a compact electric bike pump that combines fast inflation, accurate pressure control and easy portability. Weighing only 120 g, it fits neatly into a jersey pocket, saddle bag or bikepacking kit.

Set your preferred pressure, press start and let the pump handle the rest. The real-time pressure display shows the current tyre pressure while the automatic stop function switches the pump off when the selected pressure is reached.

No manual pumping. No guesswork. Just accurate tyre pressure whenever you need it.

Set the pressure and press start

The AS2 Pro reaches a maximum pressure of 120 PSI, approximately 8.3 bar. You can select either PSI or bar directly from the display.

The built-in pressure sensor monitors the tyre pressure during inflation. Once the selected target is reached, the pump stops automatically. This makes it easy to achieve consistent tyre pressure before a ride or after repairing a puncture.

Fast inflation and USB-C charging

The brushless motor provides strong inflation performance in an impressively small package.

According to the manufacturer's test figures, the AS2 Pro can inflate a 700 x 25C road tyre from 0 to 80 PSI in approximately 45 to 55 seconds. A fully charged battery can provide up to five inflations at this pressure.

The 420 mAh, 7.4 V battery charges through USB-C in approximately 30 minutes.

Built for road, gravel and everyday cycling

The AS2 Pro is an excellent choice for cyclists who want a dependable all-round electric pump.

It is especially suitable for:

• Road cycling

• Gravel riding

• Commuting

• Touring and bikepacking

• Training rides

• Emergency puncture repairs

• Accurate pressure adjustments before a ride

Presta and Schrader compatible

The pump works with both Presta and Schrader valves. The included extension hose makes valve access easier and helps protect the valve from heat produced during inflation.

Always use the extension hose with plastic or resin TPU tube valves.

Which CYCPLUS pump should you choose?

Choose the AS2 Pro when you want the best balance of low weight, accurate pressure control and strong all-round performance.

Choose the AS2 Ultra when every gram matters and you want the lightest possible option.

Choose the AS2 Pro Max when you need more airflow and battery capacity for large MTB and gravel tyres.

Please note that the pump becomes hot during operation. Use the included heat protection sleeve and allow the pump to cool between repeated inflations.
