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

A total game changer. I used to carry two CO2 canisters and a heavy inflator head. The A2S weighs less than my old setup, fits perfectly in my saddlebag, and I do not have to freeze my fingers off anymore.
Sarah Mitchell, London12 April 2026The auto-stop gauge is brilliant. I run exactly 72 PSI on my road bike, and this hits it perfectly every time. Delivery was next day to Manchester as promised.
James Henderson, Manchester11 April 2026Punctured on a freezing morning in the Pentlands. This little pump had my gravel tyre back to 40 PSI in under a minute without any effort.
Dr. Emily Clarke, Edinburgh10 April 2026Incredibly light and does exactly what it says. The silicone sleeve can be a bit fiddly with cold hands, but you need it as the unit gets warm.
Oliver Wright, Bristol9 April 2026I bought a generic brick-style inflator last year and it was too heavy for my jersey. The CYCLAMI is tiny by comparison and worth every penny.

On a full charge, the A2S can inflate two 700x25c road tyres from 0 to 80 PSI, or provide multiple top-ups for gravel and MTB tyres.
Yes for reinflating and topping up tubeless tyres mid-ride after a puncture seals. It is not a replacement for a workshop compressor when seating a stubborn bead from scratch.
