Why Choose CYCLAMI UK
CO2 vs electric pump
CO2 is fast but single-use and awkward in the cold. A2S is rechargeable, reusable and displays target PSI before auto-stop.
Presta and Schrader ready
Works with road, gravel, hybrid, e-bike and commuter valves so one compact inflator can cover most bikes in the household.
Digital PSI control
Preset from 0-120 PSI with +/- 1 PSI measurement accuracy and auto-stop to help prevent over-inflation.

“Small but terrible”
Awesome, small compact bike pump! Preset to the desired tire pressure and it does the job and fast charging too!
Review collected from another provider★★★★★
Small and convenient
This is super small and portable—I can easily carry it in my pocket or bag. Works well, and I love that it’s rechargeable via USB-C. The auto-stop function is a nice touch, so I don’t have to monitor it constantly. It takes a few minutes to inflate a tire, but it gets the job done without the hassle of a manual pump.

Frequently Asked Questions
Does the CYCLAMI A2S work with both Presta and Schrader valves?
Yes. The A2S supports Presta/French and Schrader/American bicycle valves. The matching adapters are included, so you do not need to buy them separately.
Can I preset a target pressure and let the pump stop automatically?
Yes. Set the required pressure on the digital display and the A2S stops automatically when it reaches that target. Always choose a pressure within the limits stated by your tyre and rim manufacturers.
How many tyres can the A2S inflate on one charge?
Inflation capacity varies with tyre volume, starting pressure, target pressure and temperature, so we do not state one fixed tyre count. For dependable roadside use, fully charge the pump before longer rides.
Will it fit in a saddle bag or jersey pocket, and how much does it weigh?
The pump measures 73.6 x 45 x 28.6 mm and weighs 136 g without accessories. It fits many saddle bags and jersey pockets, but storage sizes vary, so compare these dimensions with your own setup.
Does the pump get hot, and what does HOT on the display mean?
The pump can become warm during inflation. If HOT appears, its over-temperature protection has activated and the pump will stop. Avoid touching the outlet immediately after use, and allow the pump to cool before restarting or storing it.
What warranty and support are provided?
The CYCLAMI A2S includes a 12-month warranty. For warranty enquiries or product support, contact [email protected].
Can I take this on an aeroplane?
Air transport is subject to each airline and route. Check with the airline before travelling. The battery is 2 x 500 mAh / 7.4 V.
How long does it take to recharge?
Using the Type-C charging port with 5V 1.5A input, a full charge takes approximately 45 minutes.
